Peak regulation technology for industrial heating of subcritical thermal power units based on molten salt heat storage

In order to improve the peak regulation capacity of coal-fired generating units for industrial heating, proposes a new peak regulation scheme based on molten salt heat storage. Designs a molten salt heat storage system based on industrial heating and peak regulation of subcritical thermal power unit, using reheated steam to heat molten salt for heat storage and generating industrial steam by heating deaerated water with molten salt when heat supply is insufficient. The thermodynamic analysis shows that the molten salt heat storage and release system can match the parameters of thermal system of thermal power unit, and realize thermoelectric decoupling of thermal power unit.
