TEST STUDY ON CONPREHENSIVE RETROFIT OF BOILER’S HEAT RECOVERY SURFACE[J]. Thermal power generation, 2005, (9): 54-55. DOI: 10.19666/j.rlfd.2005.09.014.
锅炉尾部受热面综合改造的试验研究
摘要
针对温州发电有限公司1号锅炉排烟温度偏高的问题
提出了适当增加低温再热器和主省煤器受热面的改造方案。改造后
排烟温度下降了20℃
锅炉效率增加了0.8个百分点。按锅炉年运行5000h
一年可节约燃料2240t
经济效益显著。
Abstract
Directing against the problem of somewhat higher exhaust gas temperature from boiler no 1 in Wenzhou PowerGeneration Co Ltd
a retrofitting scheme of suitably increasing the heating surface of lowtemperature superheater and of the main economizer has been put forward. After retrofitting
the exhaust gas temperature reduces 20℃
the boiler efficiency increasing 0.8 percentage point. According to annual operation hours to be 5000 h
and price of coal to be 320 yuan (RMB) per ton
the annual coalsaving can reach 2240 t
saving fuel cost valued at 0.72 million yuan (RMB)
