A biomass boiler capable of secondary combustion

Abstract

The invention provides a biomass boiler capable of achieving secondary combustion and belongs to the technical field of biomass energy. The biomass boiler capable of achieving secondary combustion comprises a base. A box body is fixedly arranged on the base, and a combustion room and a drying room are arranged in the box body. A steam boiler close to the combustion room in an attached manner is further fixedly arranged in the box body. The steam boiler is located over the combustion room. The combustion room comprises a first grinding area, a combustion area and a second grinding area. Two sliding rails are fixedly arranged in the combustion room. A first net plate and a second net plate used for carrying biomass particles are arranged on the sliding rails in a sliding manner, the first net plate and the second net plate are fixedly connected, and a driving mechanism used for driving the first net plate and the second net plate to move back and forth is arranged in the box body. The first net plate can enter the first grinding area, and the second net plate can enter the second grinding area. The biomass boiler has the beneficial effects that secondary combustion of raw materials is achieved, and combustion is thorough.

Description

technical field [0001] The invention belongs to the technical field of biomass energy, in particular to a biomass boiler capable of secondary combustion. Background technique [0002] Biomass boiler is a type of boiler, that is, a boiler that uses biomass energy as fuel is called a biomass boiler. Biomass boilers, horizontal biomass boilers, etc. [0003] Due to the limitations of electricity, natural gas supply and gas pipelines, it is impossible to change all coal-fired boilers in my country into electric boilers or gas-fired boilers, and the low price and low operating cost of biomass boilers are easier for users to accept and promote, which just fills the gap. This blank. Biomass pellet fuel is made of waste crops such as straw, rice straw, firewood, wood chips, peanut shells, melon seed shells, beet pulp, bark, etc., and is finally made into pellets by crushing, mixing, extrusion and drying processes. fuel. [0004] Traditional biomass boilers are prone to incomplete...

Problems solved by technology

[0004] Traditional biomass boilers are prone to incomplete combustion of raw materials during use. After some raw materials are piled up, there is a lack of combustion-supporting air inside, and the raw materials accumulated inside cannot be completely burned.
