Titel: Zunderwachstum von Kupfer und Stahl bei direkter Befeuerung mit Brennstoff\u00fcberschuss<\/p>

Zusammenfassung:
Ein in Heft 3\/2016 der\u00a0 Zeitschrift Gasw\u00e4rme International<\/a> vorgestelltes Verfahren f\u00fcr die Erw\u00e4rmung von Metall-Halbzeugen in direkt befeuerten Anlagen nutzt den Prozess der Verbrennung mit Brennstoff\u00fcberschuss. Laborversuche zeigen, dass unter diesen Bedingungen bei Nutzgut aus Kupfer und einem Warmarbeitstahl gegen\u00fcber einer Erw\u00e4rmung mit Luft\u00fcberschuss signifikant kleinere Zundermengen resultieren. Auf Kupfer bildet sich bereits bei einer Luftzahl von 0,96 kein Zunder mehr, beim Stahl reduziert sich der Metallverlust bei einer Luftzahl von 0,95 um ca. 50 %.<\/p><\/div>\n\t\t\t\t\t<\/div>

The scope of the present publication is to illustrate how the application of flameless oxidation can actually represent a significant contribution to the achievement of the climate goals addressed by the European energy strategy for the future decades. The benefits and opportunities related to the utilization of the flameless oxidation technology still have large potential not only on the industrial field, but also in the private and domestic energy sector as well as in power generation plants. Basically, two methods can be addressed for the achievement of the goals set by the Energy 2020 strategy: on one hand the CO2-free power generation, on the other hand the energy conservation through higher efficiency. It can be shown how the implementation of these latter measures implies much more contained economical efforts.<\/p>

In Hochschulen und zunehmend auch in der Industrie wird die Computersimulation von Str\u00f6mung, W\u00e4rme- und Stoff\u00fcbertragung (CFD \u2013 computational fluid dynamcis) eingesetzt. Als gr\u00f6\u00dfte Schwachpunkte werden noch immer die oftmals zweifelhafte Zuverl\u00e4ssigkeit der Ergebnisse sowie die langen Berechnungszeiten angesehen. Im vorliegenden Artikel soll gezeigt werden, wie Verbrennungsvorg\u00e4nge der flammlosen Oxidation durch geeignete Wahl der Randbedingungen sehr schnell berechnet werden k\u00f6nnen. Das Ziel sind dabei Berechnungszeiten von wenigen Minuten. Die kurzen Berechnungszeiten erm\u00f6glichen ausgiebige \u00dcberpr\u00fcfung der Berechnungsmodelle und erlauben vielf\u00e4ltige Parametervariationen.<\/p><\/div>\n\t\t\t\t\t<\/div>

Die Verringerung der Abgasverluste ist in vielen F\u00e4llen die wirksamste und wirtschaftlichste L\u00f6sung zur Steigerung der Energieeffizienz von Industrie\u00f6fen. Im folgenden Beitrag werden zwei neue Brennerbauarten vorgestellt, mit denen die Abgasverluste gegen\u00fcber Rippenrohr-Rekuperatorbrennern nahezu halbiert werden k\u00f6nnen. Mit dem Regeneratorbrenner werden h\u00f6chste Wirkungsgrade erzielt, es muss jedoch ein gewisser Aufwand f\u00fcr das zyklische Umschalten und die Abgasabsaugung in Kauf genommen werden. Besonders bei Brennern geringer Leistung und bei kleinen Ofenanlagen ist dieser Aufwand bei derzeitigen Energiepreisen nicht immer gerechtfertigt. Mit dem neuen Spaltstrom – Rekuperatorbrenner werden hohe Wirkungsgrade mit einem rekuperativen System erzielt. Bei beiden Brennertypen kommt die flammlose Oxidation zum Einsatz, womit sehr niedrige Stickoxidwerte erreicht werden.<\/p><\/div>\n\t\t\t\t\t<\/div>

Betts Spring, an OEM producer of coiled springs for automotive and other uses, was established in 1868 in the San Francisco Bay area of California. They have been in business longer than most companies because they are successfully dealing with (among other things) cost increases \u2013 both production costs and the cost of living for associates. To provide a better quality of life for their employees and to control costs for the company, the management team made the decision to move their spring production operation to a new location.<\/p>

Regenerative combustion air preheating became increasingly popular due to rising energy costs. Advances in the abatement of NOx-formation made it possible to lower emissions in new installation despite high air preheating temperatures. Now, there are many regenerative fired furnaces in the steel industry, many of them in the large reheating furnaces. But there is still are large potential in energy savings. Besides the large firing capacities in reheating furnaces, there are many heat treating furnaces with smaller capacaity burners and also radiant tube heated furnaces. Small capacity regenerative burner systems require different concepts which will be discussed in the presentation.<\/p>

In recent years flameless combustion technology has been developed in order to reduce NOx emissions in combustion proceses. Within this work a significant reduction of NOx emissions was achieved by developing a novel coal flameless burner design. The objective of this paper is to examine mechanisms forming NOx in the pulverised coal air staging combustion. Within this research, determination of the fuel-NO portion out of total-NO concentrations has been done by evaluating the flue gas measurements and using Ar\/O2 mixture instead of combustion air in flameless and flame mode. Nitrogen-containing species such as HCN and NH3 and gaseous species used for calibration have been recorded using a high resolution FTIR spectrophotometer in flameless and flame mode. The effect of stoichiometry in the fuel-rich zone and the effect of furnace wall temperature were examined in flameless mode. The results show strong influence of volatile matter content in coal on NOx emission. The thermal-NO could be reduced double within flameless mode. Within flameless mode in primary combustion zone under fuel-rich conditions reducing components HCN and NH3 are dominant volatile nitrogenous species. Amount of yielded total fuel volatile nitrogen within primary combustion zone under fuel-rich condition depend on local stoichiometry. Increasing furnace wall temperature decreases fuel-NO.<\/p>

Im Beitrag wird der Einsatz kompakter Regenerativbrenner in Doppel-P-Strahlheizrohren einer Feuerverzinkungslinie beschrieben. Nach einer kurzen Darstellung der Gesamtanlage und des Gl\u00fchofens wird die Arbeitsweise des Regenerativbrenners beschrieben. Der Regenerativbrenner tr\u00e4gt durch sehr hohe Luftvorw\u00e4rmtemperaturen entscheidend zur Energieeinsparung bei und reduziert gleichzeitig durch Anwendung der flammlosen Oxidation die NOx Emissionen.<\/p>

Strahlheizrohre werden f\u00fcr die indirekte Beheizung von Thermoprozessanlagen, vorwiegend auf dem Gebiet der W\u00e4rmebehandlung von Stahl, eingesetzt. Stand der Technik sind Rekuperatorbrenner, bei denen der Brenner und der rekuperative Luftvorw\u00e4rmer eine Baueinheit bilden. Im Zuge der steigenden Energiepreise werden verst\u00e4rkte Anstrengungen unternommen, die Effizienz der Luftvorw\u00e4rmung und damit den feuerungstechnischen Wirkungsgrad noch weiter zu steigern. H\u00f6here Luftvorw\u00e4rmtemperaturen k\u00f6nnen mit einem regenerativen Luftvorw\u00e4rmer erreicht werden, der ein Einsparpotential gegen\u00fcber einem Rekuperatorbrenner von 15-25% bietet. Bislang werden Regeneratorbrenner aber im wesentlichen f\u00fcr offene Beheizung und bei h\u00f6heren Brennerleistungen eingesetzt. Im Beitrag wird die Entwicklung sowie erste Anwendungen von kompakten Regeneratorbrennern beschrieben, die kompatibel mit Rekuperatorbrennern sind. Bei der Verbrennungstechnik muss vor allem die Bildung der thermischen Stickoxide verhindert werden. Mit Hilfe der flammlosen Oxidation gelingt es, trotz der extrem hohen Luftvorw\u00e4rmtemperaturen in Verbindung mit den beengten Str\u00f6mungsverh\u00e4ltnissen im Strahlrohr niedrige NOx-Werte zu erreichen.

The demand on biomass for heat and power production has intensively increased within the last years due to the rising gas and oil prices. Up to now mostly high-quality biomass (e.g. wood pellets, untreated wood) is used for heat production but also low-grade biomass becomes more and more of interest. For utilization of low-grade biomass an advanced combustion technology is required due to its high content on inert components, e.g. nitrogen. Gasification of solid bio-residues to generate low calorific value (LCV) gases and their subsequent combustion is one of the possible conversion pathways. Within the presented work a multi-nozzle burner for LCV gases applying flameless oxidation (FLOX\u00ae) was developed that has several advantages compared to conventional flame burners. The FLOX\u00ae-burner was integrated in an existing dual-chamber furnace and four different residues from biorefinery processes were tested. Besides a more stable combustion with an improved burnout and thus a broader range of operation also a better performance due to the operation at lower excess oxygen were achieved. Furthermore the high power density of a FLOX\u00ae-burner reduces the volume of the combustion chamber by about 75 %. However, the investigations have also shown that the FLOX\u00ae-burner can only reduce thermal NO emissions but NO emissions related to fuel-bond nitrogen (e.g. in high contents in agricultural residues) are still on a high level or even increased by the flameless combustion.<\/p><\/div>\n\t\t\t\t\t<\/div>

The utilisation of low-grade biomass requires an appropriate technology that meets the increased demands regarding emission reduction (e.g. NOx). Within this work a new burner for low calorific value (LCV) gas applying flameless oxidation (FLOX\u00ae) will be presented that replaces the conventional flame burner of a dual-chamber furnace. The integration of an adapted FLOX\u00ae-burner has shown several benefits. Different bio-residues were tested and a more stable combustion with enhanced burnout was achieved for all tested fuels. Furthermore, the burner can be operated in broader range of operation and closer to stoichiometric conditions. Due to the high power density of a FLOX\u00ae-burner the complete facility could be downsized in the future. Still, the tests have shown that the NOx reduction potential of a FLOX\u00ae-burner is limited for LCV gas combustion since the most NO emissions are related to fuel-bond nitrogen. In the LCV gases generated from wheat pellets and rape cake pellets high concentrations of NO-precursors (NH3 and HCN) are measured that are subsequently be oxidized to NO in the FLOX\u00ae-burner. Therefore, an air-staged burner for N-rich LCV gases based on flameless combustion is proposed where NO-precursors can be reduced to N2 in a first substoichiometric region. CFD simulations were applied to investigate an appropriate design of an air-staged FLOX\u00ae-burner. Special emphasis is placed on the creation of a sufficient internal recirculation of flue gases required for flameless combustion. First results of CFD simulations are presented.<\/p>

Energy efficiency has become a top priority for many companies in the steel and heat treating business. Since hot exhaust gases represent the largest source for losses in most industrial furnaces, preheating the combustion air provides the highest potential for energy savings. Different strategies will be discussed in this paper in respect to their advantages but also regardings things which have to be considered. A new type of regenerative burner for radiant tube heating will also be presented. Regenerative air preheating is accepted as the most effective way to increase energy efficiency for high temperature process heating but was seen in the past as to complex and expensive for heating small and medium size heat treating furnaces.<\/p>

Das Konzept der Bio-Raffinerie setzt der simplen Holzverbrennung eine integrierte stoffliche und energetische Nutzung von Biomasseressourcen entgegen. \u00c4hnlich wie bei dem Konzept der Verbundstandorte in der Gro\u00dfchemie erfordert dies die effektive Nutzung von Nebenprodukten und Abf\u00e4llen. F\u00fcr diese Zwecke entwickeln die Firma WS-W\u00e4rmeprozesstechnik GmbH und die Universit\u00e4t Stuttgart neue Brennersysteme auf Basis des bew\u00e4hrten Prinzips der Flammenlosen Oxidation (FLOX\u00ae). Diese Entwicklung hat inzwischen zur Gr\u00fcndung der Firma e-flox GmbH gef\u00fchrt, die sich der Vermarktung dieser neuen Technologien widmet. In diesem Beitrag werden Schwachgasbrenner beschrieben, die direkt mit Vorvergasern gekoppelt werden, um feste Reststoffe zu nutzen. Die 800\u2013900 \u00b0C hei\u00dfen Gase werden in einem FLOX\u00ae-Brenner umgesetzt. Mit CO-Emissionen von < 30 mg\/m3 bei O2-Gehalten von 4% gelang es damit die CO-Emissionen gegen\u00fcber dem Stand der Technik um den Faktor 4 und die Abgasverluste um rund 25 % zu senken. Der getestete Brenner arbeitet stabil bei Sauerstoffgehalten von 3 bis 9% im Abgas. Es gelingt zwar, wie f\u00fcr FLOX\u00ae-Brenner erwartet thermische Stickstoffoxidbildung zu vermeiden, aber die auf Brennstoff-Stickstoff basierenden NOx-Emissionen k\u00f6nnen in diesem Betriebsbereich nicht reduziert werden. Aus diesem Grund wurde das Brennerkonzept zu einem gestuften FLOX\u00ae-Brenner weiterentwickelt. Dieser soll im Herbst an einer industriellen Vorvergasungsanlage getestet werden.<\/p>

Thyssen Krupp Steel started up a new 450,000 t\/year (500,000 tons\/year) galvanizing line in the fall of 2001 at their Dortmund, Germany plant. The vertical annealing furnace is equipped with a total of 189 double-P-radiant tubes. This is the first time that a vertical annealing furnace was completely furnished with the new radiant tube design. The main motive to install new radiant tube technology was to improve tube life, due to better temperature uniformity of the tube. The presentation will describe the technology and will give a status report after five years of operation with special focus on:
– tube life
– energy efficiency
– reliability
– maintenance and
– emissions<\/p>

The utilisation of low grade biofuels suffers from the lack of advanced technology. Within the European Project BIO-PRO new burner systems are developed to exploit the unused sources of gaseous, liquid and solid bio-residues. Two innovative burner technologies like flameless oxidation (FLOX\u00ae) and continuous air staging (COSTAIR) will be applied and adapted to low calorific value (LCV) gas combustion. The project objectives and the general approach for the development of two burner systems, one for gases and liquids and one for solids, are described. Results of the FLOX\u00ae-burner development and a first industrial test of a prototype burner are presented in detail. LCV gases with a minimum calorific value of 2.5 MJ\/Nm3 can be burned stably in a bench-scale FLOX\u00ae-burner. The utilisation of liquid biofuels (rapeseed oil) is successfully tested. First investigations on the fuel-NO reduction potential of the burner system show promising results. A first prototype FLOX\u00ae-burner demonstrated its fuel flexibility in a 176 hours industrial test run. The current results of the gas\/liquid burner development will now be applied to a burner that can be directly integrated in gasifiers.<\/p><\/div>\n\t\t\t\t\t<\/div>

Retrofitting ceramic single-end recuperative burners in a continuous galvanising line has provided improved availability, energy efficiency and heat flux, and reduced emissions compared to the pre-existing alloy tube system. This solution has eliminated the source of tube failures and extends the life of the tubes from 3.5 years to potentially over 10 years.<\/p><\/div>\n\t\t\t\t\t<\/div>

A new design of a preheating unit for electrical steel strip has been developed and installed in front of a continuous radiant tube furnace. The unit uses self recuperative FLOX\u00ae burners arranged in a \u201cnozzle field\u201d and is designed to preheat the strip up to 400 \u00b0C. The required heating length is reduced to one fourth of a comparable radiant tube furnace section. This implies a large reduction in specific furnace length and therefore in lay-out and investment costs. The present article describes the new fast heating unit, the feedback from industrial tests and the conclusions derived from the successful installation on the continuous annealing line.<\/p>

Natural gas prices, after an extended period of stability, have become extremely volatile in the last few years. This is only one of the challenges that companies operating heat treating furnaces are now facing. Worldwide competition is forcing companies to produce more product with fewer people. There is pressure to increase furnace uptime, while furnace operators and maintenance staff are reduced. In addition, there are tightening emission requirements and as yet unknown future carbon dioxide tariffs. These challenges are related to radiant tube heating systems. Heat treating furnaces with outdated technology will not be competitive in the future. However, much effort has been put into the development of new radiant tube designs, and there is also new technology on the market that can be adapted for heat treating furnaces.<\/p><\/div>\n\t\t\t\t\t<\/div>
