The biomass autothermal gasifier for assisting in flexible peak shaving in a thermal power plant of claim 1, wherein: the upper round platform-shaped pipe is wide in upper part and narrow in lower part, the lower round platform-shaped pipe is narrow in upper part and wide in lower part, the size of the outer round platform-shaped pipe is matched with that of the upper round platform-shaped pipe, and the diameter of an opening at the bottom end of the outer round platform-shaped pipe is equal to the inner diameter of the circular ring plate.
10. Use of a biomass autothermal gasifier for assisting the flexible peak shaving of a thermal power plant according to any of claims 1-9, characterized in that it comprises the following steps:
s1: connecting a gas sample introduction connecting pipe with a gas flowmeter and a blower in sequence, loading biomass raw materials into a biomass bin, and connecting a liquid inlet pipe with a water tower;
s2: opening switches of the blower, the biomass bin and the water tower, and adjusting the electromagnetic valve to control water flow, so that the reaction gas, the biomass raw material and the working medium water flow into the sample introduction vertical pipe;
s3: an oil gun is inserted into a reaction vertical pipe to ignite the biomass raw materials, heat is provided for self gasification, meanwhile, working medium water is heated into water vapor, the biomass raw materials are scattered on an air distribution plate, the working medium water passes through a liquid conduit and then drops into a vaporization channel, the working medium water is changed into the water vapor in the vaporization channel, and reaction gas carries the water vapor downwards to the air distribution plate after passing through a sample injection vertical pipe and is subjected to gasification reaction with the biomass raw materials on the air distribution plate;
s4: after the biomass raw material is gasified, the generated combustible gas escapes from the cylindrical pipe and then enters a gas burner of a power station boiler, and the combustible gas is combusted in the gas burner, so that the flexible peak regulation of a thermal power plant is assisted.
