摘要

燃煤机组耦合发电能够大幅度提高生物质及可燃固废的利用效率并降低机组碳排放

是今后燃煤机组低碳转型的重要途径。介绍了我国燃煤机组耦合发电的技术现状和工程案例

并分析了耦合发电对燃煤机组安全性、环保性和经济性的影响。结果表明:直接耦合发电适合耦合比例小且燃料Cl、F含量低的机组;间接耦合发电适合耦合比例大和重金属及燃料Cl、F含量高的机组;并联耦合发电不存在政策风险

但需要进行系统优化提高耦合经济性。耦合发电目前仍存在政策支持力度不够、标准规范缺失等问题。

Abstract

The coupling coal-fired power generating technology can not only significantly increase the efficiency of utilization of biomass and combustible solid waste

but also reduce the CO_2 emission from the unit. It is an important approach for transformation and low-carbon development of coal-fired power plants in future. In this study

development status and project cases for the coupling coal-fired power generating technology were presented in detail. The safe

environmental and economic effects of coupling on the coal-fired power plants were analyzed.The results show that

the direct coupling coal-fired power generating technology is appropriate to the units with low coupling ratio and low Cl and F contents in feedstocks

whereas the indirect coupling coal-fired power generating technology is suitable for the units with high coupling ratio

and high contents of heavy metals

Cl and F in feedstocks. There is no policy risk for the parallel coupling coal-fired power generating. But the system optimization is necessary for improving the economical efficiency of this coupling mode. At present

the deficiencies in policy support and standard specification are the main problems for the coupling coal-fired power generating technology.
