Biomass gasification furnace

Abstract

The invention discloses a biomass gasification furnace. The biomass gasification furnace comprises a furnace body, a feed hopper, a blanking box, a furnace grate, and a blower fan; one end of a blanking pipe is communicated with the blanking box; the blanking box is a horizontal cylindrical structure; the side wall of a rotating cylinder is provided with a feed import and export; a main blast pipeis communicated with a first branch pipe, a second branch pipe, and a third branch pipe respectively through a fourway pipe; a plurality of vertically distributed horizontal decelerating screen plates are fixedly arranged in an installation support. According to the biomass gasification furnace, the rotating cylinder is used for uniform introducing fuel into the furnace body for combustion, fuelfalling speed is accelerated via wind blowing, and sufficient air is provided for combustion; air is introduced from the upper part and the lower part of the furnace grate, fuel is contacted with theair fully, so that full combustion of fuel is realized, and more heat energy is released; hot gas generated in combustion flow upward under the action of the decelerating screen plates in the biomassgasification furnace, so that it is convenient for heating and gasification of gas, and gasification rate is high.

Description

technical field [0001] The invention relates to the biological field, in particular to a biomass gasifier. Background technique [0002] The gasification furnace is also called the straw gasification furnace, the environmental protection and energy-saving gasification furnace, and the biomass gasification furnace. By using biomass through airtight hypoxia, a combustible gas produced by pyrolysis and thermochemical oxidation is used to effectively resources utilized. The fuel of the traditional biomass gasification furnace is piled up in the furnace for combustion, the contact surface between the fuel and the air is small, the fuel is backlogged, cannot be completely burned and heated, and the gasification rate is low; the raw material is directly filled into the furnace body, a large amount of The accumulation of raw materials makes the internal air circulation poor, which is not conducive to the combustion of raw materials. Contents of the invention [0003] The purpose...
