Protective atmospheres processing for material thermal-chemical treating furnaces.
Field of application
Powder metallurgy, mechanical engineering.
Substance of development
Developed technology is based on the protective atmospheres production by the air catalytic reforming of natural gas with preheating of compressed air and natural gas by the combustion products of thermal-chemical treatment furnaces.
While in furnace operating with electric heating units the heating of catalytic reforming reagents is provided by heat of electric furnaces.
In industrial protective atmosphere generators heat supply is provided by electric heating, at that electric power intensity is 0,5 – 1,0 kWh/m3 of protective atmosphere.
Suggested technology provides at the expense of furnace heat recovery to reduce power inputs at ≥30% from total power inputs in unit – thermal-chemical treating furnace + generator on natural gas heating of furnace and at 7-8% on electric heating.
