Conclusions

A method was devised to calculate the theoretical combustion temperature of the gas-air mixture and estimate the temperature of the blast with allowance for the heat lost in the stoves and the hot-blast line.

The method was used to perform calculations in order to determine if the heating of the blast by the stoves could be improved by using a mixture of blast-furnace gas and natural gas as stove fuel, adding oxygen to the combustion air, and preheating the gas-air mixture.

For the conditions which exist at the Chusovoi Metallurgical Plant, the most economically and technically expedient method of heating the blast is the use of a mixture of blast-furnace gas and natural gas. The addition of up to 2% natural gas to the blast-furnace gas delivered to the stove burners should increase the temperature of the hot blast by at least 50°C.
