Abstract：The effects of air volume,air temperature,oxygen enrichment rate,coal injection and blast humidity on theoretical combustion temperature were calculated and studied by using the basic combustion heat balance derived formula and the existing BF operating parameters and raw fuel conditions in Masteel.The results show that under the existing raw fuel and operating process conditions of B blast furnace of Masteel,the theoretical combustion temperature changes by 1,8,8,8,8 ℃ for each change of air volume,air temperature,oxygen enrichment rate,coal injection and blast humidity by 100 m3/min,10℃,0.25％,5 kg/t and 1 g/m3.
Keywords：theoretical combustion temperatureair temperatureoxygen enrichment ratecoal injectionair blast humidity
