Embodiment Construction

[0035] In the following, the present invention will be further described by using the following embodiments in conjunction with the accompanying drawings.

[0036] figure 1 It is the slag combustion device of the biomass boiler of the present invention, which includes a slag tank 1, which is arranged at the lower end of the grate 2, and is used to receive the slag after the grate is burned; a swinging partition 11 is arranged in the slag tank 1, The swinging partition 11 divides the slag tank 1 into a slag tank 12 communicating with the boiler combustion chamber and a fine ash tank 13 communicating with the boiler superheater side, and the inner wall of the slag tank 1 is poured with heat-resistant concrete. In order to ensure that the outer wall of the slag tank is not overheated or deformed during the combustion process of the slag in the slag tank. In this embodiment, the swing partition 11 is driven by a hydraulic cylinder to swing to realize the communication and isolati...

Abstract

The invention discloses a slag combustion apparatus of a biomass boiler. The slag combustion apparatus of the biomass boiler comprises a slag groove and a slag extractor, wherein the slag groove is arranged at the lower end of a fire grate, and the slag extractor is arranged below the slag groove. A slag combustion bed capable of moving horizontally is in a hollow structure and is arranged between the slag groove and the slag extractor and communicated with combustion-supporting gas, and a plurality of air outlets are arranged on the top surface of the slag combustion bed. A shift-out side, close the slag combustion bed, of the slag groove is provided with a slag scraping part. The slag combustion bed moves between the slag combustion position and the slag extraction position. When the slag combustion bed is at the combustion position, the top end of the slag combustion bed is jointed with the bottom end of the slag groove, and a top surface of the slag combustion bed collects slag combusted by the fire grate. When the slag combustion bed is at the slag extraction position, the slag combustion bed is separated from the slag groove which is communicated with the slag extractor, and burnout slag falls onto the slag extractor. The slag combustion apparatus solves the technical problems that fuel is not fully combusted and slag is left in an existing biomass boiler.

Description

technical field [0001] The invention belongs to the technical field of biomass boilers, in particular to a slag burning device of a biomass boiler. Background technique [0002] Biomass energy is currently the most widely used renewable energy in the world, ranking fourth in total consumption after coal, oil, and natural gas. It is also the only recyclable and renewable carbon source. Biomass power generation is a mature technology for the development and utilization of modern biomass energy. It is a technology that generates heat for power generation by directly burning or converting biomass energy into combustible gas and then burning it. my country's biomass energy resources are quite rich, and biomass energy is a low-carbon energy source, which plays an important role in gradually changing my country's energy structure dominated by fossil fuels. At present, whether the boilers of biomass power plants in the world are grate furnaces with layer combustion technology or ci...
