Combustion device

Abstract

The invention discloses a combustion device, and aims to provide a combustion device with the high combustion efficiency. The combustion device comprises a frame body, a box body arranged on the framebody, a combustion pipe arranged on the box body, a spiral conveyer arranged on the box body, a draught fan of which an air outlet communicates with an inner cavity of the box body, an air distribution pipe shell which sleeves the combustion pipe and is fixedly connected with the box body, an igniter and a material pushing mechanism, wherein the igniter is arranged on the box body in a penetration mode, and the heating end of the igniter is located at the lower portion of the interior of the combustion pipe; the end, exhausting hot smoke, of the combustion pipe serves as a front end, and theother end of the combustion pipe serves as a rear end; the combustion pipe comprises an upper arc plate, and a lower arc plate which is connected with the lower end of the upper arc plate to form a combustion cavity; the diameter of the lower arc plate is smaller than that of the upper arc plate; the pipe wall of the lower portion of the combustion pipe is provided with a plurality of ventilationholes; the material pushing mechanism comprises a screw which penetrates through the box body, stretches into the combustion pipe and extends to the front end of the combustion pipe, and a gear motordriving the screw to rotate; and the screw is a hollow rod.

Description

technical field [0001] The invention relates to the technical field of biomass particle combustion equipment, in particular to a combustion device. Background technique [0002] In the existing combustion device for biomass fuel, the material is transported into the combustion chamber through a corresponding conveying mechanism to realize combustion and heat supply. Existing combustion devices will produce coke blocks during the combustion process, which will affect the combustion of fuel. Coking in existing combustion devices usually uses push rod intervals to push out coke blocks. Since fuel and coke blocks are mixed in the combustion chamber, the When the coke block is pushed out, the burning fuel is also pushed out, resulting in poor continuity of combustion and heat supply, large fluctuations in heat supply, and greater interference to constant temperature heating and control. At the same time, the materials and coke blocks are piled up at the ignition place of the com...

Existing combustion devices will produce coke blocks during the combustion process, which will affect the combustion of fuel. Coking in existing combustion devices usually uses push rod intervals to push out coke blocks. Since fuel and coke blocks are mixed in the combustion chamber, the When the coke block is pushed out, the burning fuel is also pushed out, resulting in poor continuity of combustion and heating, resulting in large fluctuations in heating, and causing greater interference to constant temperature heating and control

At the same time, the materials and coke are piled up at the ignition point of the combustion chamber, and the combustion ventilation of the materials is low, resulting in low combustion thermal efficiency.
