Description

Technical Field

[0001] This utility model relates to the field of incineration power generation technology, specifically a thermal power generation device for waste incineration power generation. Background Technology

[0002] Urban waste is collected from various waste stations by garbage trucks, weighed on a weighbridge, and stored in waste storage pits for centralized processing. When the waste storage reaches the power generation demand, the waste is fed into the incinerator's feed pit using a grab bucket. Inside the incinerator, the waste undergoes three stages: drying, combustion, and burnout, and is fully burned at a high temperature of 850-1100℃. Through the DCS automatic control system and the automatic combustion control system, the combustion conditions of the waste inside the furnace can be monitored and adjusted in real time to ensure complete combustion. The high-temperature flue gas generated from the incineration of waste undergoes heat exchange in the waste heat boiler to generate superheated steam. This superheated steam provides a steam source for the steam turbine generator set, which drives the steam turbine generator set to generate electricity.

[0003] During the operation of an incinerator, ash is inevitably generated. Once generated, this ash tends to adhere to the inside of the incinerator. The ash can hinder the effective transfer of heat to a certain extent, resulting in uneven temperature distribution inside the incinerator, which in turn affects the complete combustion of waste. Moreover, the accumulation of ash will occupy the space inside the incinerator, reducing the actual incineration volume of waste and thus reducing the amount of waste that can be processed each time.

[0004] Therefore, a thermal power generation device for waste incineration power generation is proposed. Utility Model Content
