Self-pumping type environment-friendly gasification inverse burning heating furnace

Abstract

The invention discloses a self-pumping type environment-friendly gasification inverse burning heating furnace. The self-pumping type environment-friendly gasification inverse burning heating furnace comprises a combustion chamber, a heat exchange chamber and a gasification chamber. The combustion chamber is horizontally arranged. The gasification chamber and the heat exchange chamber are both vertically arranged above the combustion chamber, and a gasification segmented type combustion U-shaped furnace body structure is formed. The position, close to a first channel, of the inner side of a topplate of the combustion chamber downwards extends to form a turbulent flow baffle. The positions, corresponding to the gasification chamber and the heat exchange chamber, of the bottom of the combustion chamber are provided with slag pits correspondingly. An air supply port is formed in the combustion chamber. The top of the heat exchange chamber is provided with a smoke discharging pipeline capable of making the negative pressure formed in the U-shaped furnace body structure. A gasifying agent supply port is in the gasification chamber, and the air supply port, the smoke discharging pipelineand the gasifying agent supply port are provided with valves for jointly adjusting and controlling the running work condition of the U-shaped furnace body structure. The self-pumping type environment-friendly gasification inverse burning heating furnace is simple in structure, convenient and fast to operate, high in combustion efficiency and little in environment pollution, and the investment cost and the running cost are reduced.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a self-pumping environmentally friendly gasification back-fired 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 furnace,...
