INDUSTRIAL BOILER HEAT SUPPLY SYSTEM, AND CONTROL METHOD AND CONTROL APPARATUS THEREFOR

WIPO Patent Application WO/2023/035149

A1

Disclosed are an industrial boiler heat supply system, and a control method and control apparatus therefor. The system comprises: an industrial boiler; a turbine; a first heat exchanger; and a high-temperature heat pump. The high-temperature heat pump is coaxially connected to the turbine; an outlet of the industrial boiler is connected to an inlet of the turbine; an outlet of the turbine is connected to a hot inlet of the first heat exchanger; a hot outlet of the first heat exchanger is connected to an inlet of the industrial boiler; a cold inlet of the first heat exchanger is connected to a hot outlet of an evaporator in the high-temperature heat pump; a cold outlet of the first heat exchanger is connected to a hot inlet of the evaporator in the high-temperature heat pump; the high-temperature heat pump is adapted to provide water greater than or equal to 80°C. In the implementations of the present invention, exhaust steam at an outlet of the turbine after work is taken as a heat source of the evaporator in the high-temperature heat pump, thereby saving energy, and also improving the working efficiency of the high-temperature heat pump.
