Especially, in 75 th united nations' congress in 2020, the general notes put forward the development targets that China needs to realize carbon peak reaching in 2030 years and carbon neutralization in 2060, and the energy problem becomes the focus of national and even international attention. For the power industry, the development direction of energy conservation, high efficiency and low emission is always explored. The modern steam power cycle mostly adopts measures such as ultrahigh main steam parameters, heat return, reheating and the like to improve the efficiency, but the thermal efficiency of the waste incineration power station is less than 20 percent, wherein after dead steam of a steam turbine enters a condenser, energy discharged to the environment by being taken away by cooling water of the condenser accounts for more than 50 percent of the total energy; in addition, the heat loss of the boiler is a non-negligible part, and according to statistics, the heat loss of the exhaust smoke of the boiler accounts for 70% -80% of the total heat loss of the boiler.

Not only utilizes the condensation heat of partial exhaust steam, but also realizes the waste heat utilization of the flue gas and the heating of a heat user.
