Gasification ratio-adjustable biomass composite combustion machine

Abstract

The invention discloses a gasification ratio-adjustable biomass composite combustion machine which comprises a combustion furnace, a furnace shell, a cooling chamber, a low-nitrogen combustor, a temperature control thermocouple, a first fan, a second fan, a feeding pipe, a feeding device, a diesel igniter, a control cabinet, a base, a vortex air pump, an automatic deslagging device, an automatic ash discharger and an ash removal and slag removal mechanism. The furnace shell is arranged on the base, the lower half portion of the combustion furnace is arranged in the furnace shell, the cooling chamber surrounds the outer side of the upper half portion of the combustion furnace, the lower end of the cooling chamber is arranged at the upper end of the furnace shell, a cooling shell is arranged on the periphery of the cooling chamber, the first fan is arranged on one side of the cooling shell and communicated with the cooling shell, the low-nitrogen combustor is located on one side of the furnace shell, one end of the low-nitrogen combustor penetrates through the cooling shell and the cooling chamber and then is communicated with the combustion furnace, a combustor air distribution pipe is arranged on the low-nitrogen combustor, and one end of the combustor air distribution pipe is communicated with the cooling shell.

Description

technical field [0001] The invention relates to the technical field of biomass composite burners, in particular to a biomass composite burner with adjustable gasification ratio. Background technique [0002] With the continuous popularization and application of biomass energy, there are many elements that can be used in production practice, but some shortcomings are also highlighted, that is, the biomass direct-fired or semi-gasification burner has a simple structure and low cost, but Large dust, high nitrogen-containing gas emissions, and a certain gap with environmental protection requirements. The full gasifier is environmentally friendly and has high thermal efficiency, but the cost is high, which is difficult for users to accept. In order to overcome the above defects, a compound gasifier that can adjust the gasification ratio is designed. Burner. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects...
