Environment-friendly gasification counter-flow combustion hot-blast stove

Abstract

The invention discloses an environment-friendly gasification counter-flow combustion hot-blast stove. The environment-friendly gasification counter-flow combustion hot-blast stove comprises a combustion chamber, a heat exchange chamber and a gasification chamber for gasification and combustion of fuel. The combustion chamber is horizontally arranged, and both the gasification chamber and the heat exchange chamber are vertically arranged above the combustion chamber to form a gasification section type combustion U-shaped stove structure. The bottom of the gasification chamber and the bottom of the heat exchange chamber are connected with the combustion chamber through a first channel and a second channel respectively. The position, close to the first channel, of the inner side of a top plate of the combustion chamber stretches downwards to form a turbulent flow baffle. Positions, corresponding to the gasification chamber and the heat exchange chamber, of the bottom of the combustion chamber are respectively provided with a slag pit. The environment-friendly gasification counter-flow combustion hot-blast stove is simple in structure, convenient and quick to operate, high in combustion efficiency and small in environment pollution, and investment cost and operation cost are reduced.

Description

technical field [0001] The invention relates to a hot blast stove, in particular to an environment-friendly gasification countercurrent combustion hot blast stove which can be widely used in industrial drying and energy-saving heating of agricultural greenhouses, independent buildings, industrial workshops, public venues and rural households. Background technique [0002] A stove is a device used to heat air. In the past, hot blast stoves had defects such as serious flue gas pollution, low thermal efficiency, difficult to control combustion, and large hidden dangers; although some hot blast stoves that have appeared in recent years have improved thermal efficiency and improved flue gas pollution, the furnace structure It is relatively complex, has high and single requirements for fuel, frequent feeding, and cumbersome manual operations, which increase investment costs and operating costs. Therefore, this type of hot blast stove is difficult to be widely promoted and used. ...
