High energy consumption is one of the main problems in the process of steel smelting production. Large amount of residual heat resources and fuel gases produced during this process can be recycled to improve the utilization rate of energy. Due to the low temperature of the residual heat and low calorific value of the fuels, it is difficult to reuse them. Based on the combined cycle power plant (CCPP), a new comprehensive energy utilization system was proposed and discussed in this paper. In this system, the steady-state combustion perform for the fuel with low calorific value (800~1200kcal/m3) can be obtained by improving flame tube, nozzle and swirler of combustor; the low temperature residual heat can be used in steam turbine cycle of CCPP; comparably the high temperature residual heat can be utilized in gas turbine cycle of CCPP. The efficiency of heat-electricity conversion can be significantly improved by using new blade shape in coal gas compressor and inter-cooling compressor. By optimizing the configuration of CCPP, the efficiency of the whole system was increased by 20%.
