Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of biomass boilers, and particularly relates to a biomass fuel boiler for industrial steam supply and a use method thereof. BACKGROUND

[0002] Biomass refers to various organic bodies generated by air, water, land and the like through photosynthesis, that is, all living and growing organic matters are collectively referred to as biomass. From the simplest use value, most of the biomass can be used as a heat supply raw material for boiler combustion. Biomass energy heat supply is a green, low-carbon and clean economic renewable energy heat supply mode. It has flexible layout and wide application range, can collect raw materials on site and consume nearby, reduces open-air burning of straw in rural areas, and can replace scattered coal consumption in counties and rural areas to build a distributed clean heat supply system in cities.

[0003] In the process of industrial steam supply, a biomass fuel boiler is often used. The biomass fuel in the biomass boiler is usually processed by compression. For example, a biomass boiler is disclosed in Chinese Patent (Application No. 201810482991.X). When used by a user, the biomass boiler can pre-add material and ensure that the feed inlet and the material adding port of the storage place are opened and closed at the same time during pre-adding, so that when the equipment is used, the sparks or combustible materials cannot ignite the stored material in the storage hopper, and even if the sparks or combustible materials are splashed into the pre-adding device, only the pre-adding material can be burned, ensuring safety and facilitating use. Although the above technical problems are solved, the volatile matter in the biomass fuel will be rapidly combusted after volatilization. During the combustion of fixed carbon, the internal fixed carbon is difficult to contact with air due to the compact texture, resulting in slow combustion or even incomplete combustion of the fixed carbon. In addition, the ash generated after the surface of the fixed carbon burns will adhere to the surface to block the contact between air and the internal fixed carbon. Moreover, during the use of the biomass fuel boiler, the material is concentrated in a certain position in the boiler during feeding, making it difficult for the material to fully contact with air and resulting in low combustion efficiency. Therefore, a biomass fuel boiler for industrial steam supply and a use method thereof are needed to solve the above problems. SUMMARY
