摘要
为解决焦炉烟道气余热能源浪费和其对周围环境污染的问题,利用高温烟道废气通过风机引入换热锅炉,直接产生蒸汽用于干熄焦锅炉加热除氧器用汽,进而提高了干熄焦余热的发电量;实现了焦炉烟道废气余热利用,降低了焦炉烟道废气排放温度及污染物含量;相对减少了相同蒸汽产量锅炉的烟气排放量。不仅具有节能的直接经济效益,而且更重要的还具有明显的环境效益。
To solve the problem of coke oven flue gas waste heat energy waste and its surrounding environment pollution problem,using high temperature flue gas heat exchange boiler,introduced by the fan,direct heating oxygen is used to produce steam is used to dry quenching boiler steam,then improve the dry quenching waste heat power generation; implements the coke oven flue gas waste heat utilization and reduce the coke oven flue gas emission temperature and contaminants; relatively reduces production the same steam boiler flue gas emissions. Not only has direct economic benefits of energy saving,but also has obvious environmental benefits.
