摘要:

以徐州华润电力有限公司300MW机组为例,利用机组热力参数及低温省煤器改造后运行参数,通过等效焓降计算和低温省煤器投切试验两种方法,对低温省煤器改造的节能效果进行评价。评价结果验证了理论计算思路及方法的正确性,实际应用时可以用两种方法互相校核。

Abstract:

Take a 300MW unit of Xuzhou Huarun Power Company Limited as an example, using the unit’s thermal parameters and operational parameters after the low temperature economizer modification, it compares energysaving effect of low temperature economizer with two methods in which the equivalent enthalpy drop calculation and low temperature economizer switching test are used. The evaluation results verify the correctness of the theoretical calculation and the method, and the two methods can be used for mutual check.
