燃煤、燃气锅炉综合效益模糊评价及分析结果——以乌鲁木齐市集中供热锅炉为例

以乌鲁木齐市某集中供热站锅炉节能减排方案为例,通过建立供热锅炉实施方案综合评价指标体系,运用层次分析法确定方案各项指标权重,利用模糊综合评判法分别从锅炉燃煤、燃气情况下的环境效益、经济效益以及设施能耗、物耗等指标着手,进行综合评价,并对集中供热锅炉燃煤与燃气方案综合评判结果进行分析,最终评选出较优实施方案。评选结果表明:燃气方案综合效益较好,可有效实现节能减排,为今后燃气锅炉建设提供一定的参考作用。

Comprehensive Benefits Fuzzy Evaluation and Analysis on Coal Fired and Nature Gas Boiler Case Study of Central Heating Boiler in Urumqi

This paper takes the energy - saving and emission reduction scheme of a central heating station boiler in Urumqi City as example. Through the establishment of heating boiler implementation plan and comprehensive evaluation index system as well as use of fuzzy comprehensive evaluation method respectively from the coal burning and nature gas burning case from the environmental benefits, economic benefits, facilities energy consumption, material consumption etc. index to proceed comprehensive evaluation. The comprehensive evaluative results of central heating boiler coal buming and nature gas burning were analyzed. At last, the opti- mal implementation plan was selected. The results show that gas scheme achieve better comprehensive benefits and can achieve the energy saving and emission reduction goals efficiently. This paper provides reference for future nature gas boiler construction.
