Problems solved by technology

[0002] Before the present invention, the fluidized bed method that was often used to prepare biomass combustible gas used air as the gasification agent, and its main disadvantage was that the calorific value of the combustible gas produced was not high; if steam was used as the gasification agent, external heating was necessary To provide the necessary heat of reaction, the twin-bed fluidized bed gasifier is one of the methods to provide heat, but it brings the complexity of structure and operation, and the cost is also high

Abstract

The invention relates to a fluid bed biological mass gasification furnace employing heat pipe for heat supply, wherein superheated steam is loaded into a fluid bed as gasifying agent, a heat pipe is employed to supply the reaction heat needed by the reduction reaction between the biological mass and the steam, one segment of the heat pipe is arranged in the reactor as a heat output section, the other segment is arranged in the combustion chamber as a heat adsorption segment, and the residual heat of the fuel can produce gasifed steam.

Description

technical field [0001] The invention relates to a biomass gasification furnace, in particular to a fluidized bed biomass gasification furnace using heat pipes for heating. Background technique [0002] Before the present invention, the fluidized bed method that was often used to prepare biomass combustible gas used air as the gasification agent, and its main disadvantage was that the calorific value of the combustible gas produced was not high; if steam was used as the gasification agent, external heating was necessary To provide the necessary heat of reaction, the twin-bed fluidized bed gasifier is one of the methods to provide heat, but it brings the complexity of structure and operation, and the cost is also high. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, and provide a fluidized bed biomass gasification furnace using heat pipes for heating. [0004] Technical scheme of the present invention is: ...
