Description

Technical field: [0001] The invention relates to the improvement of the structure of a straw burning furnace. Background technique: [0002] There are many kinds of straw burners at present, but most of them follow the combustion form of coal stoves, and it is difficult to play the characteristics of straw combustion, so the combustion efficiency is not high. Invention content: [0003] The present invention aims at the above problems and provides a straw gasification combustion furnace which is more suitable for straw burning and has high combustion efficiency. [0004] In order to achieve the above object, the present invention adopts the following technical scheme. The present invention includes a furnace body, which is a combustion chamber. It is a slagging screw; the furnace wall with ventilation holes of the combustion chamber and the furnace shell are secondary air passages; the outlet of the combustion chamber is a swirl nozzle with spiral blades; the inlet of the...
