Abstract

The invention provides a power generation system using waste heat of coke oven crude gas, and solves the problems that the waste of conventional coke oven heat energy is larger, and a large amount of split products in the crude gas are consumed without return. The power generation system comprises a waste heat gas passage, a waste heat boiler, a turboset and a generator set which are connected in sequence; the waste heat gas passage is connected with a coke oven rising pipeline; a superheater, an evaporimeter and an economizer are arranged in the waste heat boiler in the gas flowing direction in sequence; the economizer is connected with a softened water pump outlet; and the superheater is connected with the turboset through a steam pipeline. The power generation system is simpler, equipment is easy to arrange, the occupied area is small, the temperature of the raw coke oven gas is reduced from 650-750 DEG C to 82-86 DEG C since the crude gas is cooled, and meanwhile, about 60% of tar is cooled and collected in a mechanization slot for recycling.

Description

technical field [0001] The invention relates to the technical field of heat utilization of raw coal gas of coke ovens, in particular to a power generation system utilizing waste heat of raw coal gas of coke ovens. Background technique [0002] The coking industry develops along with the development of iron and steel enterprises, and it is also one of the basic industries of the iron and steel industry. At the same time, the coking industry is also a large energy consumer (according to relevant information: the energy consumption of coking plants accounts for about 50% to 60% of production capacity). Among them, the heating consumption in the coking process accounts for about 45% to 50% of the gas production, so the coking industry is also an important industry for energy saving and emission reduction. [0003] During coking, about 75% of coal turns into coke, and about 25% produces various chemical products and gas. The recovery of these chemical products is of great signif...
