Abstract

The invention discloses a cyclone gasifying stove, which includes upper and lower portion, wherein the upper portion is in cylinder shape, and lower portion is in taper shape. Cylinder shaped combustion and gasification chamber and cylinder shape gasification chamber are disposed in upper portion of the stove; and taper shaped gasification chamber is arranged in lower portion. A splash board is set in upper portion of cylinder shaped gasification chamber, smoke outlet is opened on the top; fuel inlet is arranged in upper portion of cylinder shaped combustion and gasification chamber and in direction of tangent line of furnace wall, resistant wire igniter is located in fuel inlet, steam inlet is disposed in center portion of taper shaped gasification chamber, ash outlet is disposed at bottom; cylinder shaped gasification chamber is in cylinder shaped combustion and gasification chamber, and configured coaxially with the taper shaped gasification chamber. The invention integrates combustion chamber and gasification chamber, compact in size, simple in process, low in production cost, high in quality of produced gas.

Description

1. Technical field [0001] The invention relates to a gasification furnace, which is mainly suitable for the gasification of powdery biomass and coal, especially for powdery biomass and the like. 2. Background technology [0002] With the depletion of petrochemical energy and the increasingly serious environmental hazards caused by combustion, clean coal utilization technology and renewable clean biomass energy utilization have been widely concerned. To this end, my country has introduced relevant policies and increased investment in scientific research to promote the clean utilization of coal and expand the scale of biomass energy utilization. At present, coal and biomass gasification technology research and application have been widely carried out all over the world. [0003] In 2007, Shen Deyun invented an atmospheric pulverized coal gasifier (patent number: 200720011795.1). The basic structure is: the upper part of the furnace body is a vertical cylinder with an arched ...
