Description

A kind of biomass air-heating furnace

Technical field

The utility model relates to heating of house field, specifically a kind of biomass air-heating furnace.

Background technique

The heating of northern China rural area is mainly made a fire a heatable brick bed and with coal-burning stove for heating stove heating water, then by water by heat band It radiates both modes to room heater piece.There is the high-density biology matter by processing in more developed rural area at present The stove of grain and mating controlled burning, but due to cost etc., it is not widely applied also.In recent years, with the hair of social economy Exhibition, rural area heating are gradually converted into burn based on coal.Coal belongs to fossil fuel, and fossil fuel further includes petroleum and day combustion Gas is the most commonly used a kind of energy of the mankind.This kind of energy is that carbon is fixed to shape in the earth's crust by the biology before hundreds of millions of years At, combustion of fossil fuels is re-released into this part carbon in atmosphere, and carbon emission described in environment protection field just refers to this One process, the coal that thus burns will increase carbon emission.And biomass fuel is that plant utilizes solar energy the dioxy in atmosphere Change the carbohydrate that carbon and other nutrients are solidified to form by photosynthesis.When biomass combustion, carbon therein with The form of carbon dioxide turns again in atmosphere.This plant absorbs carbon from atmosphere and carbon is released back into atmosphere again Process can be completed in a cycle generally within most decades, be formed to burning relative to fossil fuel up to number In 100000000 years carbon cycle periods, can be ignored, thus biomass fuel by it is internationally recognized be fuel that carbon emission is zero, be one Kind clean reproducible energy.Under the main trend of current mankind Social Ecology development of civilization, it should encourage more biomass Replacement of fuel fossil fuel.

Rural area heating by the way of the biomass burnings such as heated kang, the stove that the overwhelming majority does not modernize, is usually used Brick mixes the hearth that material is constructed in kitchen, or even directly directly burns in the flue of a kang of bedroom.Not only efficiency of combustion obtains this mode It less than guarantee, and causes indoor environment dirty, is unfavorable for improving rural resident's living standard.And fire coal will cause carbon emission, The megatrend of energy-saving and emission-reduction is not met.Under current rural area existence conditions, heating stove is all small-sized or even miniature stove, Efficiency of combustion is far below large-sized boiler, and exhaust gas can not also use cost-effective processing mode, so as to cause incomplete combustion, cigarette The discharge of the other harmful substances such as dirt is higher, causes provincialism, period air pollution.
