Self-suction environment-friendly gasification inverse combustion heating furnace

Abstract

The invention discloses a self-suction environment-friendly gasification inverse combustion heating furnace. The self-suction environment-friendly gasification inverse combustion heating furnace comprises a combustion chamber, a heat exchange chamber and a gasification chamber. The combustion chamber is arranged horizontally, the gasification chamber and the heat exchange chamber are vertically distributed above the combustion chamber, and therefore a U-shaped furnace body structure for gasification sectional combustion is formed. A turbulent flow baffle extends downwards from the position, close to a first channel, of the inner side of a top plate of the combustion chamber, and the 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. An air supply port is formed in the combustion chamber, a smoke discharging pipeline enabling negative pressure to be formed in the U-shaped furnace body structure is arranged at the top of the heat exchange chamber, a gasification agent supply port is formed inside the gasification chamber, and the air supply port, the smoke discharging pipeline and the gasification agent supply port are provided with valves used for regulating and controlling operating conditions of the U-shaped furnace body structure together. The self-suction environment-friendly gasification inverse combustion heating furnace is simple in structure, convenient and rapid to operate, high in combustion efficiency, low in environment pollution, and capable of reducing investment cost and operating cost.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a self-pumping environmentally friendly gasification reverse-firing heating furnace which can be widely used in industrial drying, agricultural greenhouses, independent buildings, industrial plants, public venues and rural households for energy-saving heating. Background technique [0002] In the past, there were defects such as serious smoke pollution, low thermal efficiency, difficult to control combustion, and large hidden dangers; some furnace types that have appeared in recent years have improved thermal efficiency, but the structure of the furnace type is relatively complicated, and the requirements for fuel High and single, the operation and maintenance are cumbersome, which increases the investment cost and operating cost. Contents of the invention [0003] The purpose of the present invention is to provide a self-pumping environment-friendly gasification reverse-firing heating furn...
