Cyclone-combustion stove

Abstract

The invention discloses a cyclone combustion stove comprising a cylindrical upper portion and a conical lower portion. A cylindrical combustion-gasification chamber and a bell-shaped gasification-combustion chamber are disposed at the upper portion of the stove; a conical gasification chamber is disposed at the lower portion of the stove. A fuel inlet provided with a resistance wire igniter disposed therein is disposed at the upper portion of the cylindrical combustion-gasification chamber and is disposed along a tangential line of the stove wall; an ash blocker is disposed at the upper portion of the bell-shaped gasification-combustion chamber, a gas outlet is disposed at the top of the bell-shaped gasification-combustion chamber, and an ash outlet is disposed at the bottom of the bell-shaped gasification-combustion chamber; the bell-shaped gasification-combustion chamber is disposed in the cylindrical combustion-gasification chamber, and both the bell-shaped gasification-combustion chamber and the cylindrical combustion-gasification chamber are arranged axially with the conical gasification chamber. The combustion stove can combust powder fuel sufficiently with a combustion efficiency of more than 90, and the combustion heat energy can be used for boilers, stoves, power generation, and heating etc.; the structure of the cyclone combustion stove is compact so that production cost thereof is reduced greatly.

Description

1. Technical field [0001] The invention relates to a combustion furnace, which is mainly suitable for the combustion of pulverized fuel, especially for pulverized biomass and the like. 2. Background technology [0002] With the depletion of petrochemical energy and the increasingly serious environmental hazards of combustion, the technology of clean coal utilization and the utilization of renewable clean biomass energy 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, advanced combustion technologies of coal and biomass have been extensively developed around the world. [0003] In 2002, Wu Hanmin invented a boiler device that uses chaff and straw as fuel (patent number: 02153420.9). The basic structure is: the hinge of the upper hopper is installed at the furnace entrance, the chain grate...
