摘要
本文对城市生活垃圾在流化床中与煤的混烧技术进行了分析;根据垃圾热值;讨论了低热值垃圾焚烧中添加煤混烧的必要性;给出了垃圾处置收费和售电价格对于混烧电厂的经济影响。结果表明:对于所给定焚烧项目的垃圾来讲,其垃圾的低位热值近似为 4200 kJ/kg,需要进行混烧,其中煤的比例应小于10～20％;垃圾量的提高,垃圾收费带来的收益九;而垃圾热值的提高,售电价格带来的收益大。增加垃圾收费补贴可鼓励焚烧厂焚烧更多的垃圾。
In this paper, the co-combustion technology of municipal solid waste with coal in FBC was analyzed. The co-combustion is necessary for waste due to its low heat value. Economical influences of waste fee and electrical price on waste co-combustion plants were analyzed. The results indicate that for the waste studied in the incineration object, co-combustion technology is necessary since the heat value of waste is 4200 kJ/kg, and the coal ratio in mixed fuel should be less than 10%~20%. Increasing handling ou...
