Increasing the energy efficiency of combined heat power plants by reducing the temperature of the additional feed water of power boilers

The article discusses a fundamentally new technology for increasing the specific generation of electricity based on thermal consumption, and also calculates the effectiveness of the proposed solution. The main distinguishing feature of this solution is a decrease in the temperature of the additional feed water of the boilers of thermal power plants. As a result, a method was developed to increase the specific power generation based on heat consumption by reducing the temperature of the additional feed water of power boilers. The authors have developed a technical solution for the use of gas entering the burners to cool additional feed water through a heat exchanger-cooler; a study of the economic and energy efficiency of the proposed technical solution has been carried out.
