Abstract:

Take a 300MW 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 energysaving 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.

Key words:

low temperature economizer, energysaving effect, equivalent enthalpy drop, coal consumption for power supply
