A kind of multi-stage combustion furnace with furfural slag as fuel

Abstract

A multi-stage combustion furnace using furfural slag as fuel belongs to the technical field of furfural slag combustion. In order to solve the problem of insufficient combustion in a single-layer combustion method, and uneven distribution of furfural slag on a fire bed surface will lead to insufficient combustion The operation of the equipment is unstable, and the evaporation equipment needs to be set to dry the slag before combustion, which causes the problem of waste of resources. The linkage assembly on one side of the feeding assembly, the outer edge of the rotating plate is provided with a tooth slot, the bottom of the second linkage shaft is fixedly connected with a limit rod, and the linkage assembly also includes a limit plate arranged on the second screen. The rod and the fixed rod drive the movable ring to shake the material up and down, and the end gear drives the second screen to rotate inside the movable ring, so that the small particles of slag evenly pass through the second screen and fall into the first screen, so that the combustion is fully , to achieve multi-stage combustion of furfural residue fuel.

Description

technical field [0001] The invention relates to the technical field of furfural slag, in particular to a multi-stage combustion furnace using furfural slag as fuel. Background technique [0002] Furfural slag refers to the waste slag produced during the refining of furfural. Its sodium and magnesium content is not high, and it contains a small amount of chlorine, aluminum and iron, while the content of silicon, sulfur, potassium and calcium is high. It is affected by the pretreatment process. The water content is very high (55.2%), and there is a little acid residue. The stacking of a large amount of furfural slag will not only pollute the water body and soil, but also occupy the site and cause air pollution if it is stacked for a long time. Therefore, a new type of environmentally friendly boiler is developed and developed. To deal with waste furfural residues has great positive significance for effectively utilizing waste resources, improving ecological environment, and im...
