低温省煤器对350 MW机组的热经济性影响

Thermal Economy Impact of Low Temperature Coal Saver on 350 MW Unit

以廊坊热电厂350 MW机组为例,建立低温省煤器的物理模型和基于等效热降理论的热经济性模型,在不同工况下对热经济性进行计算。结果表明:加装低温省煤器能够提高机组热经济性,实现节能降耗的目的,故该方案可为提高运行中机组热经济性提供参考方案。

Taking the 350 MW unit of Langfang thermal power plant as an example,a physical model of low-temperature coal economizer and a thermal economy model based on the equivalent heat drop theory were established,and the thermal economy was calculated under different operating conditions.The results show that the retrofitting of low temperature coal economizer can improve the thermal economy of the unit and achieve the purpose of energy saving and consumption reduction,so the scheme can provide a reference solution for improving the thermal economy of the unit in operation.
