Abstract

The invention discloses a garbage-incinerating circulated power-generating system, which relates to the technical filed of garbage-incinerating power generation and comprises a garbage incinerator, a steam turbine, a steam condenser, a surplus-heat boiler, a first air preheater, a smoke-gas purifying device and a chimney, wherein the garbage incinerator is communicated with a superheater in the surplus-heat boiler, a coal economizer in the surplus-heat boiler is communicated with the smoke-gas purifying device, the smoke-gas purifying device is communicated with the first air preheater, and the first air preheater is also communicated with the chimney and the superheater in the surplus-heat boiler; and the steam condenser is communicated with the coal economizer in the surplus-heat boiler, and the steam turbine is communicated with the superheater in the surplus-heat boiler. Through adopting the garbage-incinerating circulated power-generating system, the heat utilization ratio in the garbage-incinerating power-generating process can be improved, thereby the power-generating efficiency is improved, high-temperature corrosion caused by high-temperature smoke gas can be reduced, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of waste incineration power generation, in particular to a waste incineration cycle power generation system. Background technique [0002] At present, in the process of waste incineration power generation, the flue gas produced by the waste incinerator is highly corrosive, which restricts the improvement of the steam parameters of the waste incinerator, and makes its overall thermal efficiency lower than that of general power plant boilers. [0003] Such as figure 1 As shown, the working process of the existing waste incineration cycle power generation system is as follows: first, the waste enters the waste incinerator and burns to generate high-temperature flue gas, and then the high-temperature flue gas passes through the superheater, evaporator, and economizer of the waste heat boiler to recover heat energy, and then the flue gas Exhausted into the atmosphere through the flue gas purification device and ...
