Abstract

The invention provides a utilization system of power station boiler flue gas waste heat. The utilization system comprises heat pipes, a flue gas passage and an air passage. The heat pipes comprise evaporating ends and condensation ends, wherein the condensation ends are arranged in the air passage; the evaporating ends absorb waste heat of flue gas in a boiler flue and transmit heat to air in theair passage through the condensation ends; and the air after being heated enters a boiler furnace for aid combustion, and stabilizing devices are arranged in the heat pipes. According to the utilization system of the power station boiler flue gas waste heat, a utilization device and method of flue gas waste heat with a novel structure is provided, a heat source is fully used, the energy consumption is reduced, and the flue gas discharging effect is improved.

Description

technical field

[0001] The present invention is a part of the subject project jointly researched and developed with the enterprise, relates to the field of waste heat recovery of heat pipes, in particular relates to a method and device for recovering waste heat of flue gas by using heat pipes. Background technique

[0002] With the rapid development of my country's economy, energy consumption is increasing day by day, and the problem of deteriorating urban air quality is becoming more and more prominent. It is urgent to save energy and reduce the emission of harmful environmental substances. In the common steam generation process, one of the main reasons for high energy consumption and serious pollution is that the exhaust temperature of boiler flue gas is too high, which wastes a lot of energy. Therefore, the waste heat of boiler exhaust gas is recovered and reused to achieve energy saving and emission reduction. purpose, while protecting the environment. However, in the p...
