The blast quantity, pressure, temperature, humidity, oxygen enrichment rate, wind speed at the tuyere (or blast kinetic energy), flame temperature in front of the tuyere and other parameters shall be determined according to the furnace capacity, equipment conditions, raw materials, fuel conditions, tuyere injection conditions and smelting iron. Volume of air entering blast furnace in standard state per unit time (m3 / min or m3 / h). Under the same conditions, the greater the air volume, the higher the output.
