Embodiment Construction

[0021] As shown in the accompanying drawings, the pollution-free heating coal-fired gasification furnace has a furnace body 5, a furnace liner 17, a hot water coil 9, a heating water heater 2, a gas purifier 32, a gas storage tank 36, and an air extractor 7 , an air pump 33, a grate closing mechanism, and a raw smoke utilization device.

[0022] There is an inclined partition 24 inside the furnace 17, which divides the inner cavity of the furnace into a coal storage chamber X and a gasification chamber Y. There is a coal inlet at the lower end of the inclined partition 24, and there is a coal inlet at the coal inlet. Switch 18, turn the knob 39, make the coal feed switch 18 be in an upright state, the coal will enter the gasification chamber Y from the coal storage chamber X, and carry out incomplete combustion and gasification in the gasification chamber Y and the lower combustion chamber Z.

[0023] Generate coal gas, then be sucked away by air extractor 7 and the pipeline 6...

Abstract

The invention discloses a pollution-free heating coal combustion gasifier belonging to the field of energy-saving environment-friendly equipment. The gasifier is characterized by consisting of a furnace body, a furnace liner, a hot water coil pipe, a heating hot water furnace, a coal gas purifier, a gas storage tank, an gas extractor, an air pump, a fire grate closing mechanism, and a generated smoke utilization device. The pollution-free heating coal combustion gasifier disclosed by the invention has the beneficial effect that a scientific design thoroughly eliminates defects of an up-draft coal combustion gasifier and a down-draft coal combustion gasifier. The coal gas generated by gasification of the pollution-free heating coal combustion gasifier is high in carbon monoxide content, the coal gas quality is effectively improved, fuel coals are saved, and the exhaust gas emission is clean and free from pollution, so that the comprehensive living costs and social costs of users are greatly reduced.

Description

[0001] Technical field: [0002] The pollution-free heating coal-fired gasifier belongs to the field of energy-saving and environment-friendly equipment. [0003] Background technique: [0004] The technology of modern coal-fired gasifiers is developing rapidly, and a hundred schools of thought are contending. At present, there are mainly two types of coal-fired gasifiers, updraft and downdraft, on the market, but they all have important defects: the defect of the updraft is that when the furnace cover is opened, the smoke is strong, which affects the market. The main factor of the downdraft type is that the coal-fired gasification chamber is located above the combustion chamber, and the hot gas generated by coal combustion is directly sucked away, which is not conducive to coal-fired gasification, and the carbon dioxide content in the sucked away hot gas is too high , the carbon monoxide content is insufficient, thus can not provide high-quality gas. [0005] Invention conte...
