Application Prospect of the New Technique of Combination Production of Heat, Electricity and Gas in Metallurgical Enterprises

The combination production technique is to closely combine circulation fluidized-bed combustion boilers with dry distillation gas producers so as to realize the combination production of electricity, heat and gas in a set of system. The process and key technique of the combination production of heat, electricity and gas are presented in this paper. Feasibility of the technique used in metallurgic enterprises, especially used in Hangzhou Iron &Steel Co. is analyzed. It considers that the technique has the advantages of less investment, low cost and small technical risk, which is the best way for Hangzhou Iron &Steel Co. to solve the problem of demand for gas, heat and electricity.
