Direct-fired auto-warming biomass gasifier

Abstract

The invention discloses a direct-fired auto-warming biomass gasifier, which comprises a furnace body of an updraught gasifier in the prior art, an ash outlet, a discharge chimney and a fan, and is characterized in that: a cooking range is arranged on the upper part of a hearth and is integrated with the furnace body; an auto-warming pyrolysis combustion cooking range and a closed pot holder are arranged; a fuel gas releasing tube and a fuel gas releasing valve leading to the discharge chimney are arranged on one side of the top part of the hearth; one side of the upper part in the furnace body is provided with a charging hole; and a manually rotated ash dispelling, blanking and air intake device is arranged at the bottom of the hearth. The direct-fired auto-warming biomass gasifier has the advantages that: pipelines and a stove eye are not blocked caused by condensation and deposition any more; thermal efficiency is improved; pungent smell is removed; fuel does not overflow any more when a cover is uncovered to feed materials; indoor air is not polluted; the gasifier is not burnt out and fire is not cut off any more; ash is easily dispelled and the materials fall easily; and normal combustion and gas generation are guaranteed. The direct-fired auto-warming biomass gasifier is more suitable for popularization and application in energy conservation and emission reduction and construction of new rural communities.

Description

Technical field [0001] The invention relates to the comprehensive utilization of crop stalks, and is a gasifier for converting waste biomass from agriculture, forestry and animal husbandry into combustible gas through oxygen-limited combustion pyrolysis reaction. Especially updraft domestic gasifiers. Background technique [0002] At present, the updraft gasifier in the prior art is simple in structure, low in cost, and has a wide range of straw resources, and because of the global concern about the energy crisis and the air pollution caused by seasonal burning of straw and other agricultural waste, the party The country and the country attach great importance to the development and utilization of renewable energy, encourage and advocate straw energy, in order to alleviate the energy shortage in our country, and strive to achieve both energy saving and environmental protection; And stoves, also often cause secondary pollution due to condensed water overflow, thus restrictin...

Problems solved by technology

[0003] In order to overcome the disadvantages that the existing gasification furnaces usually use separate devices to purify and then transport them to the stove for combustion through pipelines, which will cause the gas to gradually cool down on the way to condense and deposit tar and water vapor in it, thereby blocking the pipeline and the stove. The technical solution adopted is: the stove head is directly arranged on the upper part of the furnace and combined with the furnace body as a whole, so that the high-temperature mist gas in the furnace does not need to be output from the furnace and directly enters the stove head for combustion in a high-temperature environment that has not been cooled, achieving no longer Purposes clogged by condensation deposits
