冷热电三联供系统研究（9）：“煤改气”应首选燃气冷热电三联供系统

摘要

Aiming at the process of substituting gas for coal,queries the blind practice of using gas-fired boilers to replace coal-fired boilers.Thinks that there are three ways for substituting gas for coal, namely,gas-fired power station,gas-fired boiler and gas CCHP system.Analyses some problems existed in substituting gas for coal when gas-fired boiler is used as the first choice.Combined with project cases, illustrates that gas CCHP should be the best way to substitute gas for coal.%针对目前“煤改气”过程中一味将燃气锅炉替代燃煤锅炉的做法提出质疑，认为“煤改气”有3条途径———燃气发电厂、燃气锅炉和燃气冷热电三联供系统（CCHP），分析了将燃气锅炉作为“煤改气”的最佳选择存在的诸多弊病，通过工程实例说明“煤改气”应首选燃气CCHP。
