Combustion furnace structure of biomass combustor

Abstract

The invention provides a combustion furnace structure of a biomass combustor. The combustion furnace structure is spanned at the two ends of a body through a beam, the beam is connected with the body, a cooling liquid capable of being circulated is provided inside the beam; the beam is communicated with a liquid layer on the inner wall of the furnace body to achieve a radiating effect; a ring-shaped tube is connected with the body, the cooling liquid capable of being circulated is filled inside the ring-shaped tube; the ring-shaped tube is communicated with the inner wall of the furnace body to achieve the radiating effect; meanwhile, the size of the ring-shaped tube can be flexibly designed according to the dimension of the body; besides, the beam and the ring-shaped tube can be used for supporting and placing refractory bricks, so that the refractory bricks are guaranteed to be spliced very well. Compared with the prior art, not only can the limitation of jointing with fewer refractory bricks be avoided, but also the combustion furnace structure with a certain size can be completed, so that the furnace top lid cannot be applied to a greater combustion furnace. Through the beam and the ring-shaped tube, the size of the combustion furnace structure can be flexibly controlled to adapt to combustors with different sizes.

Description

technical field [0001] The invention relates to biomass burning equipment, in particular to a biomass burner combustion furnace structure. Background technique [0002] With the implementation of national energy conservation and emission reduction policies and the enhancement of people's awareness of environmental protection, as well as the increasing demand for energy in industrial production, the problem of increasingly tight energy supply is becoming more and more serious. The wood chips that were originally discarded are also used as bioenergy. , Biomass energy has attracted more and more attention. [0003] The existing biomass burner has a furnace roof on the combustion furnace. The combustion furnace is mainly used to burn biomass to generate heat. The furnace roof mainly plays a sealing role. The furnace roof is formed by splicing refractory bricks. The size of the brick is limited, and the general furnace roof structure is limited to a certain radius due to the lim...

Problems solved by technology

[0003] The existing biomass burner has a furnace roof on the combustion furnace. The combustion furnace is mainly used to burn biomass to generate heat. The furnace roof mainly plays a sealing role. The furnace roof is formed by splicing refractory bricks. The size of the brick is limited, and the general furnace roof structure is limited to a certain radius due to the limitation of refractory bricks. It is only suitable for smaller combustion furnaces, and the corresponding furnace roof cover cannot be completed for larger combustion furnaces.
