Abstract

A fuel boiler of plant powder type is prepared for setting material feeding mouth and floss hole and ignition opening on furnace wall, arranging slag hole under furnace wall, fixing flue pipe guide wall on furnace wall in furnace body and setting said guide wall between floss hole and material feeding mouth in parallel to chain fire-grate, extending one end of material feeding pipe on fan into burning chamber and connecting another end of material feeding pipe on fan with external fan of furnace body and material feeding box as well as material feeding machine. Its burning method is also disclosed.

Description

Technical field: [0001] The invention relates to a boiler and a combustion method for directly burning plants such as straws which are crushed into fine powders as powdered fuels. Background technique: [0002] At present, raw coal is the main fuel for boilers. Since raw coal is a non-renewable resource, the price continues to rise, and raw coal will produce sulfur dioxide and other pollutants during the combustion process, and there will be a large amount of solid residue after combustion, causing great pollution and high treatment costs. , equipment investment is large, seriously restricting the development of enterprises. Straw and other plants come from a wide range of sources in our country. Because of their low economic benefits, they are randomly stacked or burned in rural areas, seriously affecting traffic and polluting the environment. The use of conventional boilers and their combustion methods using crops such as straw as fuel has low combustion efficiency and ca...
