Description
Technical field
The present invention relates to a kind of biomass boiler field of fuel additive technology, more particularly to a kind of biomass boiler are special
Environmentally friendly scarfing cinder deashing agent.
Background technology
Become increasingly conspicuous recently as the energy, environmental issue, biomass is as regenerative resource, due to its abundant money
Source is laid in and the characteristic of environmental protection, payes attention to further for countries in the world.At present, absorbed through introduction in a few years, it is domestic biomass direct-fired
Technology reaches its maturity, and the biomass boiler number of units of operation is also growing day by day.
It is entirely different with coal-burning boiler, biomass boiler because fuel is mostly plant property, in fuel rich in potassium, sodium,
Calcium, etc. alkali metal, caused a large amount of flying dusts are easily in heat exchanger surface aggregation, precipitation, slagging after being burnt in stove.Especially fire
During with crops fuel, problems are more prominent, and biomass fuel carries substantial amounts of sandy soil mostly simultaneously, most main in silt
It is silica to want composition, when fuel burns in boiler fire box temperature often be far above 800 DEG C, at this temperature silica with
Alkali metal in fuel reacts, and generates the compounds such as substantial amounts of sodium metasilicate, potassium silicate, the ash fusion point of these compounds is often
Less than 900 DEG C, in furnace flame centre in melting soft state, when the flying dust of these softenings leaves flame kernel with flue gas
These positions will be adhered to when touching the positions such as water-cooling wall, superheater beam tube, form incrustation.These incrustation can be adhered to quickly
The chlorate in dust granule and flying dust in flue gas, so as to produce new coking and dust stratification.
Incrementally increased recently as Environmental Protection in China dynamics, the biomass boiler quantity on various regions are new is also increasing.By
In fuel particularity, all there is different degrees of dust deposition in most biomass boilers.In general, biomass boiler
Operation just needs blowing out ash-cleaning and coke-removing in 50~60 days or so, and its method used is all that blowing out carries out artificial ash-cleaning and coke-removing at present,
For processing means mainly using physics modes such as mechanical soot blowing, broken, the angle removing dirts of impact, ash-cleaning and coke-removing working strength is big, and such as
Misoperation easily causes pipe fitting breakage, and the safe operation to boiler brings hidden danger.
In the existing technology in China, for the decoking product comparative maturity of coal-burning boiler exploitation.It is but commercially available
Coal-burning boiler decoking product is very poor for the cinder treatment effect of biomass boiler.This be due to flying dust caused by coal-burning boiler,
The composition of clinker is totally different from the boiler of biomass burning, thus its caused coking and dust stratification property, composition, ratio are poor
It is different it is huge caused by.Specifically, coal fuel produce coking dust stratification be primarily due to itself containing carbon, sulphur, moisture and other
Dirt, the flue gas formed after its burning, forms CO2-SO3Air system, when encountering all kinds of heat exchangers, its table
Temperature is far below flue-gas temperature on face, separates out each constituents in flue gas, so as on the one hand cause to form corruption in boiler heating surface
Corrosion extremely strong sulfate and sulphite, on the other hand the ash content in adhesion flue gas, finally makes to form one on boiler heating surface
Kind is not easy to disperse, tough lime-ash.And biomass fuel is formed because itself containing the elements such as substantial amounts of chlorine, potassium after burning
Furnace atmosphere it is complex, in its dust stratification and slagging both contain because sulphite corrode the ferrous sulfate to be formed, while
It is sufficiently complex containing the compounds such as substantial amounts of potassium chloride, silica, chemical composition.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of biomass boiler special environment protection scarfing cinder deashing agent is provided.
