<p>FIELD: production of furnace black. SUBSTANCE: method provides for reaction of fuels and oxidizer. Introduced into flow of combustion products is raw material to form reaction flow containing gas block. Additional oxidizer and raw material are introduced into reaction flow simultaneously or in succession. As a result, additional gas black is formed. Device for production of gas black includes combustion zone provided with means for introduction of fuel and oxidizer, zone of raw material injection into flow of combustion gaseous products furnished with means for introduction of raw material, means for introduction and reaction of reaction flow with additional oxidizer, and additional raw materials, zone of separation and gathering of gas block. EFFECT: reduced amount of fuel consumption for unit of black. 39 cl, 1 dwg, 5 tbl</p> |
