Walking Beam Heating Furnace Cold Charging Low Nitrogen Combustion

Cold Charging Low Nitrogen Combustion Walking Beam Heating Furnace
Walking Beam Heating Furnace Cold Charging Low Nitrogen Combustion

This project involves the design, manufacture, construction and installation, masonry, coating, commissioning of cold and hot state, personnel training and turnkey project of a walking beam heating furnace with rated output of 35 t/h (cold installation) until normal operation.

It adopts low-nitrogen combustion system, via the two-stroke preheater to preheat combustion air to 350℃, fully recover flue gas heat, save fuel consumption at the same time, reduce the cost of combustion system and spare parts and long-term maintenance, significantly reduce the operating cost; Both theory and practice have proved that fuel consumption can be reduced by 5% when combustion air is increased by 100℃.
