Problems solved by technology

[0002] The biomass semi-gasification furnace or biomass direct combustion furnace needs to provide primary and secondary air from the outside during the combustion process to make the combustion stable and complete. There are problems such as insufficient combustion, low thermal efficiency, long start-up time of the cold furnace, fire off, large smoke emission, and a lot of combustion dust, and the secondary air distribution device is integrated with the furnace body, which brings great inconvenience to the cleaning and maintenance of the furnace body. inconvenient

Embodiment 1

[0011] Embodiment one, the secondary air distributor of biomass direct combustion furnace, such as figure 1 As shown, it is an annular hollow body surrounded by inner wall 1, outer wall 2, upper wall 3 and bottom wall 4, with a fire hole 5 in the middle; Air holes 6; the inner wall 1 has a louver-shaped air outlet 1 7, and the bottom wall 4 has a louver-shaped air outlet 2 8; the upper wall 3 and the bottom wall 4 each have two reinforcing ribs 9.

[0012] When installed and used, the secondary air distributor of the biomass direct-fired furnace is flexibly connected with the furnace body and placed above the furnace cylinder. The outer wall 2 is close to the stepped inner wall of the furnace body, and the air inlet 6 is connected to the external secondary The air is supplied by air, and the inverted conical outer wall 2 can prevent the assembly of the furnace body from being too tight or loose due to heat deformation, and it is easy to take out; because the biomass direct com...

Abstract

A secondary air distributor for a biomass direct combustion furnace relates to a biomass stove and is arranged above a boiler. The secondary air distributor comprises a hollow cavity formed by enclosing an inner wall, an outer wall, an upper wall and a bottom wall, wherein the middle part is provided with a fire hole; an air inlet is arranged on the outer wall; a first air outlet is arranged on the inner wall; and a second air outlet is arranged on the bottom wall in order to fully combust the secondary air for compensating combustion by rotating the air. The secondary air distributor of the invention has simple structure, is characterized by easy ignition of cool furnace, quick combustion, high heating efficiency, strong fire power, being free from blow-off, less exhaust emission, and the like, and is specially fit for the biomass direct combustion furnace.

Description

technical field [0001] The invention relates to a biomass direct combustion furnace, in particular to a secondary air supply and distribution device in the combustion process of the biomass direct combustion furnace. Background technique [0002] The biomass semi-gasification furnace or biomass direct combustion furnace needs to provide primary and secondary air from the outside during the combustion process to make the combustion stable and complete. There are problems such as insufficient combustion, low thermal efficiency, long start-up time of the cold furnace, fire off, large smoke emission, and a lot of combustion dust, and the secondary air distribution device is integrated with the furnace body, which brings great inconvenience to the cleaning and maintenance of the furnace body. inconvenient. Contents of the invention [0003] The purpose of the present invention is to provide a secondary air distributor of a biomass direct-fired furnace with simple structure, ea...
