扬子石化公司在实施了火炬气回收系统改造后 ,由于其电厂锅炉设计燃用火炬气量小 ,不能完全燃用回收的火炬气 ,使公司仍存在火炬气火炬排放、从而造成环境污染及能源浪费的问题。通过热力计算及不同掺烧火炬气比例试验 ,证明可提高锅炉掺烧火炬气比例到4 0 %。 After the implementation of the reform of the flare gas recovery system, Yangzi Petrochemical Company still can not discharge the flare gas because of the small amount of flare gas used in its power plant boilers. As a result, flare gas flares still exist in the Company, resulting in environmental pollution and energy waste problem. Through the thermodynamic calculation and different proportions of flare gas mixture experiments, it is proved that the proportion of the flare gas blended into the boiler can be increased to 40%.
