摘要

通过对135MW循环流化床(CFB)锅炉机组效率的火用分析

揭示了其发电过程中各环节的火用效率及火用损失。分析表明

对于135 MWCFB锅炉机组

燃烧与传热火用损失最大。提出了降低燃烧和传热火用损失、凝汽器背压、飞灰含碳量等提高机组系统性能的方法。

Abstract

The exergy efficiency and loss of each link in power generation was revealed by exergy analysis for efficiency of a 135 MW unit with circulating fluidized bed(CFB) boiler.Results show that

for the135 MW unit that working with the CFB boiler

the exergy loss during combustion and heat transfer process are the two maximum parts of all exergy losses.Meanwhile

to improve the performance of the unit system

methods for decreasing such indexes as the exergy loss during combustion and heat transfer

the condenser backpressure and carbon content in fly ash etc.are discussed.
