The invention provides a method, equipment and a system for detecting and controlling a gasification furnace. The method comprises the following steps: receiving at least one frame of gasification furnace throat image shot continuously; analyzing the pixel point data in the at least one frame of gasification furnace throat image, and determining feature data corresponding to the combustion detection parameters in the gasification furnace according to an analysis result; according to the characteristic data, determining combustion detection parameters in the gasification furnace, and accordingto the detection parameters in the gasification furnace, controlling equipment assisting in combustion of the biomass fuel in the gasification furnace. By utilizing the method, the throat air distribution condition of the gasification furnace can be optimized; the combustion conditions of pyrolysis gas and tar are improved; the judgment accuracy of the throat section temperature is effectively improved; according to the biomass gasification furnace, the phenomenon of uneven combustion in a cold area is reduced, so that the gasification rate and the fuel gas heat value of the system are improved, the rate of biomass charcoal conveyed to the gasification furnace by the feeding system can be visually reflected, and the variable load response speed of the biomass gasification furnace is effectively increased in combination with air supply equipment for adjustment.
Description
Technical field [0001] The invention relates to the field of gasification furnace combustion power generation, in particular to a method, equipment and system for detecting and controlling a gasification furnace. Background technique [0002] At present, there are two main methods for thermal power generation through fuel: one is to generate electricity by burning coal fuel through traditional boiler burners, and the other is to burn biomass pyrolysis gas to generate electricity, among which biomass pyrolysis gas is burned to generate electricity. It uses thermochemical methods to convert biomass raw materials into H 2 , CH 4 Synthetic gas such as, CO, etc., which is finally sent to the internal combustion engine for combustion and power generation. It is characterized by small unit scale, low equipment investment, short construction period, and fast response to variable load, which is especially suitable for distributed power generation application scenarios. [0003] Biomass raw ...
