A method for heat utilization of outlet furnace gases of hot-blast stoves involves supplying and discharge of gas fuel and air combustion in gas and air heat-exchanger, discharge of the spent furnace gases from the air heat-exchanger and from gas heat-exchanger, discharge of gas fuel from gas heat-exchanger and air from air heat-exchanger, supplying of fresh combustion products from under gas-fired furnace into the exhaust duct, and also it has a connection of smoke inlet with the heat-exchangers with its outlet in which the consumption of combustion gases through the air heat-exchanger is regulated by a pressure-difference device. |
