Energy Saving Analysis in the Cold End System of Existing 300MW Turbine with Heat Pumps for Heating

This article is according to the actual situation of two units of 300MW turbine generator and 9sets of heating pumps combined heating thermal plant analyze and calculate the turbine cold end system energy saving effect. From the analyzing, after the thermal plant increased the heat pump, the heating supply increased 351.7021GJ/h, the heating areas increased 1953.89 thousand square meters, save the circulating water quantity 72t/h, energy utilize efficiency increased 8.01%. From the data, we can know that the new power and heat cogeneration mode using the thermal plant circulating water system as heat pump hot end have conspicuous energy saving effects.
