Reciprocating grate of small biomass boiler

Abstract

The invention discloses a small biomass boiler reciprocating grate, which comprises a base, a grate, a grate fixing cross beam, a movable steel frame, a riding wheel device, an air supply device and a transmission device, and is characterized in that the base comprises a lower bottom plate and two side plates; the fire grate comprises a material pushing fire grate and a combustion fire grate; the material pushing fire grate consists of a movable material pushing fire grate and a fixed material pushing fire grate; the combustion fire grate consists of a plurality of movable combustion fire grates and a plurality of fixed combustion fire grates; the movable steel frame is composed of a plurality of fire grate movable cross beams and two longitudinal beams connected to the two sides of the fire grate movable cross beams. The fire grate movable cross beams are parallel to each other and are arranged in a staggered manner; the riding wheel device is used for supporting the movable steel frame; the air supply device is used for supplying air into the air chamber area; the transmission device is used for driving the movable steel frame to linearly reciprocate in the advancing direction of the fuel. When the reciprocating grate of the small biomass boiler works, automatic feeding, automatic coke breaking and automatic slag removal are achieved through reciprocating motion between the grates.

Description

technical field [0001] The invention relates to the technical field of boiler combustion equipment, and more specifically relates to a reciprocating grate of a small biomass boiler. Background technique [0002] At present, most of the grates used in small biomass boilers are fixed grates. However, some biomass fuels will produce slagging during the combustion process, which is easy to block the grate, resulting in no ventilation, so that the grate cannot be cooled well. Burn out early. [0003] In addition, the fuel cannot be supplied with oxygen in time, which not only affects the normal combustion of the boiler, and the thermal efficiency is low, but also causes black smoke during the use of the boiler. At the same time, the boiler needs to be manually opened after slagging, which increases labor intensity and wastes manpower. [0004] Therefore, how to effectively solve the above technical problems is an important research direction for those skilled in the art. Conte...

Problems solved by technology

[0002] At present, most of the grates used in small biomass boilers are fixed grates. However, some biomass fuels will produce slagging during the combustion process, which is easy to block the grate, resulting in no ventilation, so that the grate cannot be cooled well. burn out early

[0003] In addition, the fuel cannot supply oxygen in time, which not only affects the normal combustion of the boiler and has low thermal efficiency, but also causes the phenomenon of black smoke during the use of the boiler. At the same time, the boiler needs to be manually opened after the slagging, which increases the labor intensity and wastes manpower.
