Description
Technical field
The utility model relates to a kind of standardized fuel that glows.
Background technology
Glowing is a kind of special combustion system, refer in solid matter, occur without gas phase flame, often follow the smoulder process of incomplete combustion product, generally occur in particle media porosity and looseness or that pile up.Its outstanding feature is that process is slow, is particularly suitable for the little load heating of Rural areas discrete distribution.
China has many application of glowing traditionally, smouldering etc. such as the common handwarmer in rural area and while burning a heatable brick bed.The glow example of heating of the at present spontaneous application of northern area peasant is a lot, combustion pond in Hebei, there is application on the ground such as Liaoning, Heilungkiang, Shandong more.According to 2011 Chinese agriculture statistical information, then in nearly 200,000, the combustion pond of using.
Foreign study mainly be take fire preventing and to reduce fire damage be object, research smoldering process characteristic, mechanism, products distribution etc.Adopt experimental study and two kinds of methods of theoretical analysis.Experimental study glows communication process, internal temperature characteristic, product gas characteristic, process with variation of ambient conditions etc.And analyze theoretically the reason of these characteristics.More complete in the analysis of smoldering process theoretical side abroad, particularly Princeton University has carried out detailed theoretical and experimental study to smoldering process.But they are mainly conceived to the analysis of phenomenon, for application aspect research seldom.
Domestic research be take fire preventing on the one hand as object, is applied as on the other hand object to glow.Mainly take experimental study as main, also in conjunction with corresponding theoretical analysis.Research contents comprises that combustion pond Performance Detection, combustion pond are for effect, the feature of glowing of agricultural facility etc., the exploitation of the stove that glows, the gas detection etc. of glowing, the material smoldering process experiments such as foam and theoretical analysis etc.
Summary of the invention
Of the present utility modelly provide a kind of standardized fuel that glows, it is provided with oxidation catalyst filter layer, can remove tar and incombustible substance in flue gas, and more clean, the process of making to glow is more easily controlled.
The concrete technical scheme adopting of the utility model is:
The standardized fuel that glows, it is placed in the casing that glows, and it is characterized in that, and the described standardized fuel place Min layers that glows is located in the casing that glows, and the described standardized fuel that glows comprises biomass fuel bed and oxidation catalyst filter layer; Wherein, biomass fuel layer thickness >=30 centimetre; Described oxidation catalyst filter layer is biomass ash, and its thickness is 5-6 centimetre.
In described biomass ash, include with metal oxide that cocrystallization form does not exist and the mixture of silicon-dioxide, oxidation catalyst filter layer can be 700～900 ℃ of coal-tar middle oil cracking of catalysis flue gas, and the rate of rotation of its catalytic pyrolysis is more than 85%.
For obtaining with metal oxide and silicon-dioxide that cocrystallization form does not exist, described biomass ash is being less than burning acquisition under 800 ℃ of conditions by biomass.
Described biomass fuel bed is biomass powder or biological particles.
Or described biomass fuel bed is straw bundle and the biomass powder laid in straw bundle, described biomass powder is a kind of or any mixture in straw powder, leaf, shell, rice husk, sawdust, melon seed cases, Pericarppium arachidis hypogaeae.
Wherein, described biomass ash is the combust of rice husk that ash content is higher, rice straw, corn stalk, straw.
The scheme that the utility model stdn fuel is more preferably is:
The described stdn fuel that glows comprises casing, and in casing, place Min layers is provided with biomass fuel bed and oxidation catalyst filter layer, wherein, and biomass fuel layer thickness >=30 centimetre; Described oxidation catalyst filter layer is biomass ash, its thickness 5-6 centimetre.
In such scheme, after described standard fuel is made, can unify to be dispensed into user.
Compared with prior art, the utility model has the advantages that:
(1) ecological friendly: fuel can be gathered materials on the spot, products of combustion ash content can be done fertilizer application, is real energy-saving and environmental protection, green, capable of circulation, sustainable agriculture technology.
(2) fuel standard: the many agriculture and forestry organic waste materials that directly adopt of the current application of glowing.Because agriculture and forestry organic waste material is lack of standardization, combustion processes is difficult to control, and majority reduces combustionvelocity to add water.This burning and control cause smoldering process incomplete combustion product more, and in flue gas, particulate matter, aerosol account for certain ingredients.The utility model carries out stdn to fuel, proposes the fuel that contains filtering layer, Catalytic Layer.This standardized fuel, controls the standard of glowing and the purification of flue gas becomes possibility.
(3) fume emission: meet the < < of Beijing boiler air pollution emission standard > > (DB11/139-2007), and owing to adopting biomass fuel, sulphur dioxide emission are significantly smaller than fire coal.
Soot emissions <10mg/m
3standard is: 10mg/m

Sulfurous gas <1mg/m
3standard is: 20mg/m
3
Oxynitride <65mg/m
3standard is: 150mg/m
