“GREEN STEEL”, BY ESA
Reliability and sustainability in reheating furnaces with ESA burners
In the steel mills, preheating semi-finished products in large continuous furnaces before rolling is critical. The ‘Walking Beam,’ ‘Walking Hearth,’ or ‘Rotary Hearth’ type furnaces, although releasing huge heat quantities, must strictly follow given temperature profiles in each zone to ensure the quality and yield of the final product. Additionally, the ‘Green steel” challenge requires today the possibility to use hydrogen, blends, off gases and any kind of available green fuels even liquid.
ESA leads the way in addressing these challenges, supplying complete solutions targeting efficiency and sustainability. First of with the refractory head burners, long fame (for lateral use) or radiant type (for roof use), in recuperative or regenerative options, guarantee flame stability and precision when delivering huge heat quantities to the process using both traditional or hydrogen or green fuels and blends. Oxy fuels burners are also available, for various applications.
Rege Nxt long flame regenerative burners
Sidewall burners up to 4 MW which preheat the air through integrated regenerative beds with alumina spheres. Available for traditional fuels (NG, LPG), hydrogen, other process gases.
RAD Nxt radiant flame recuperative burners
Roof mounted radiant flame burners with pre-heated air via central recuperator.
ENM Nxt long flame recuperative burners
Sidewall burners up to 4 MW that exploit the heat of a central recuperator. Available for traditional fuels (NG, LPG), hydrogen, other process gases.
Special burners for process gases
Customized burners for gases with low calorific value (COG, BFG, SYNGAS...).
Long flame recuperative burners for liquid fuels ENM DF Nxt
Sidewall burners for liquid fuels and biofuels with compressed air atomization.
Air/Oxy fuel burners
Burners that use oxygen or air as oxidizers for traditional or green fuels. Various customization possibilities.
POINT OF STRENTGH
Our special expertise in exploiting green and off gases
ESA is the ideal partner in the development of burners and skids to use hydrogen as well as process gases with even very low calorific values, otherwise burned in torches into atmosphere, thus lowering fuel consumption and emissions reductions. Contact us today to find out how we can help you!
