Through analysis of the thermal equilibrium to the coke oven, it's determined that the sensible heat recoveries of the hot coke physical thermal energy, crude gas, and combustion waste gas are the main three aspect of the residual heat recovery in coke production. Among these, hot coke physical thermal energy is prime recovery resource with an approximate occupation of 35% of the total coke oven heat. On studying to the production processing of coke oven gas purification system, residual heat resource composite, energy system structure, and the state of the art of the recovery of the heat source, it's determined that the way of residual heat resource utilization is mainly to modify the chemical processing and the high temperature recovery processing medium, the energy system mainly adopts home-grown energy resource (coke oven gas. etc.) in stead of direct outsourcing.
