Abstract

A small horizontal shell-type coal-water slurry boiler relates to the technical field of boilers; a fire tube is arranged in the boiler body, a steel frame is arranged at the bottom of the boiler body, a vertical flue is connected to one side of the boiler body, and a vertical flue is installed in the vertical flue There is a convection heating surface, the lower part of the vertical flue is provided with a dust removal door, the bottom of the vertical flue is provided with an ash bucket, the vertical flue is connected with the combustion chamber, and a burner is arranged on one side of the combustion chamber; The upper part of the vertical flue is provided with an ash door, one side of the ash door is provided with an ash platform, and one side of the ash platform is provided with a control room; the boiler body is connected with the dust collector, and the dust collector is connected with the dust collector. The induced draft fan is connected, and the induced draft fan is connected with the chimney through the tail flue. The small horizontal shell-type coal-water slurry boiler of the present invention can solve the problems of traditional small-scale horizontal shell-type coal-water slurry boilers and ash accumulation, ash discharge, and coking, and the smoke pipe at the rear tube plate of the boiler is not easy to be blocked by ash. The equipment has a long service life.

Description

technical field

[0001] The invention relates to the technical field of boilers, in particular to a small horizontal shell-type coal-water slurry boiler. Background technique

[0002] Coal water slurry is a coal-based fluid fuel developed in the mid-1970s. It is made of about 70% coal, about 30% water, and a small amount of chemical additives. It has the same fluidity as petroleum. It can be pumped, atomized and ignites stably. It can be transported and stored in pipelines over long distances. Coal water slurry has higher combustion efficiency, much lower pollution emissions than raw coal, and is convenient for storage and transportation. Therefore, it has good economic and environmental benefits. It can replace traditional polluting fuels such as coal and heavy oil in industrial boilers.

[0003] The pulping and combustion technology of coal water slurry has been relatively mature, and has been successfully applied in some power plants and industrial furnaces, but there ar...
