Slag breaking apparatus for biomass combustor and realization method

Abstract

The invention relates to a slag breaking apparatus for a biomass combustor and a realization method. A motor I drives a small gear to rotate, the small gear drives two engaged large gears to rotate, two slag breakers fixedly connected with the two large gears rotate in a face-to-face manner, the slag-bonding biomass fuel successively moves toward the slag breakers by virtue of an ash inlet and anoblique surface of a guide plate, the slag-bonding biomass fuel is driven by two end surfaces of large semicircles of the two slag breakers to enter a plurality of grooves which are arranged correspondingly, a plurality of large semicircles enter the plurality of grooves to crush the slag-bonding biomass fuel, and the crushed biomass fuel is discharged from a lower port of an ash discharging box.The slag breaking apparatus has the beneficial effects that the slag breaker of the slag breaking apparatus is formed by a plurality of eccentric wheels, i.e., concentric cam sheets, and the pluralityof eccentric wheels are divided into two groups and arranged in an intersecting manner on an ash outlet on the tail end of the combustor. By adopting the structural design of the slag breaking apparatus, the reside, i.e., coke fragments generated by the biomass combustor can be crushed in an engagement manner at any time and then is discharged from the lower port of the ash discharging box, so that the combustion quality of the biomass combustor can be ensured.

Description

technical field [0001] The invention relates to a slag breaking device and a realization method for a biomass burner, which is a supporting device of the biomass burner. Background technique [0002] At present, most of the existing domestic biomass fuel boilers are transformed from traditional coal-fired boilers, which generally have disadvantages such as low combustion efficiency and high exhaust gas temperature, especially the fuel characteristics that cannot adapt to the high sugar content of straw. During the combustion process of biomass fuel, it is affected by changes in humidity, combustion temperature, oxygen permeability, combustion support, and displacement speed. The slag phenomenon affects the normal operation of the biomass burner, making it difficult for these boilers to be put into practical application. [0003] Our company has launched the intelligent biomass fuel boiler project with crop straw as the main fuel, and cooperated with the "industry-university...
