Biomass air heater

Abstract

The invention discloses a biomass air heater which comprises a spiral feeder, a hopper, a cabinet body and a plate type heat exchanger. An induced draft fan is installed at the upper end of the cabinet body, moving wheels are installed at the lower end of the cabinet body, an ash outlet is formed in the lower side of the front end of the cabinet body, and an ignition fan is arranged at the rear end of the cabinet body. According to the biomass air heater, cold air introduced by the combustion fan is heated in an encircling mode in the furnace wall, the heated hot air enters a combustion chamber through a secondary air port, sufficient oxygen can be provided for a hearth to make biomass particles combusted sufficiently, a large quantity of black smoke and volatile components are reduced, and the heat loss can be reduced; cold and heat isolation is adopted in the heat exchange process of the plate type heat exchanger, the obtained hot air is clean and free of contamination, the heat exchange area is sufficient, and the heat exchange amount is larger; biomass particle fuel can be provided for a combustion furnace through the spiral feeder, biomass fuel such as fuel wood and straw can be provided for the combustion furnace through a furnace door, and multiple feeding modes are achieved; and the biomass air heater is small in size, movable and capable of working flexibly.

Description

technical field [0001] The invention relates to the field of hot air blowers, in particular to a biomass hot air blower. Background technique [0002] Biomass energy is the fourth largest energy consumption in the world, after the three conventional energy sources of oil, coal and natural gas, and has a broad application market. As a new type of biomass fuel, biomass pellet fuel is clean and efficient, and can replace fossil fuels such as coal. It is widely used in civil fields such as cooking and heating, and large industrial fields such as power generation, heating, and drying. At present, there are few studies on small and medium-sized biomass hot air devices, and the existing biomass hot air devices have defects such as insufficient combustion, large amount of black smoke, poor heating effect, and inflexible operation. Contents of the invention [0003] The object of the present invention is to provide a biomass hot air blower in order to solve the above problems. ...
