Description
Technical field
The present invention relates to biomass recirculating fluidized bed boiler technical fields, more specifically to a kind of biomass circulating
Fluidized-bed combustion boiler anti-coking additive and preparation method thereof and application method.
Background technology
As fossil fuel drains off, new energy revolution makes biomass energy be greatly developed.Biomass is rich with its
Richness, renewable, neutral carbon, low stain, widely distributed feature have obtained the approval of all circles, as it is a kind of it is more clean can
Regenerated carbon source can be converted into conventional power generation usage fuel, compare with potential nature, the thermoelectricity of Ecological Environment Risk, nuclear energy, water power,
And the wind energy by regional resource restriction and geothermal power generation, the rare limitation of biomass power generation and query.China has abundant
Crops and the forest reserves, biomass power generation project, which turns waste into wealth agriculture and forestry organic waste material, is converted into high-grade electric energy, and realization can be held
Supervention exhibition.But since biomass fuel chlorine, potassium content are high, alkali metal potassium can be precipitated in gaseous form when burning, with low melting point sulphur
Hydrochlorate, chloride form condense on fly ash granule, reduce flying dust fusing point, increase ash surface stickiness, cause flying dust to exist
The slagging coking of heating surface, causes the thermal efficiency to decline；Alkali metal chloride is further reacted with sulfur dioxide in cinder, is generated
Chlorine and hydrogen chloride gas aggravate the corrosion in metal heated face.Serious slagging will block exhaust gases passes, increase wind turbine power consumption,
So that carbonated drink pipe is overheated booster, destroys equipment continuous operation, greatly shorten boiler continuous operating time.To prevent slagging, one is forced
A little boilers are run at low load for a long time, cause huge economic loss.Conventional coking processing method：Generally blown using steam
Grey device carries out coking deashing processing to heating surface, but from the point of view of actual effect, there are purging limited areas, accelerate metal tube
Wall is worn, and increases inner flue gas of the stove humidity, and the harm of low-temperature corrosion is formed at air preheater, and decoking is not achieved and requires.
The mode of addition coke-removing agent is mostly used at present to reduce biomass boiler slagging coking.Biomass boiler is anti-at present
Coking additive types are limited, wherein representative patent have CN101775324A, CN105238494A,
CN205295275U, they are with kaolin, Al2O3, effective based on calcium oxide but suitable to different types of biomass fuel
Answering property is poor, and dosage is big, and economic cost is high；CN106479597A, CN104371789A, CN104479790A are with nitrate, sulfuric acid
Ammonium, calcium carbonate, magnesium carbonate based on binder, are assisted with water, effective but can increase smoke moisture, aggravate heated surface corrosion,
Large-scale application is poor.Although above-mentioned dirt-resistant additive has decoking effect, but dosage is big, of high cost, to different types of
Biomass fuel bad adaptability, use scope are restricted, and the industrialization formula being extremely difficult to truly is promoted.Therefore, not
Under the premise of adjusting boiler structure, seek it is a kind of it is economical, efficiently, biomass circulating stream that various biomass fuels are adapted to by force
Fluidized bed boiler decoking additive is just particularly important.
Invention content
The technical problem to be solved in the present invention is, provides a kind of economical, efficiently, adapt to by force various biomass fuels
Biomass recirculating fluidized bed boiler decoking additive and its preparation and application method.
The technical solution adopted by the present invention to solve the technical problems is：Construct a kind of biomass recirculating fluidized bed boiler

In SO2(g) come assist gangue fix potassium, weaken KCl and SO2(g) reaction generates the K of low melting point2SO4；Ca (OH) simultaneously2
With CaO, SiO in ash2Reaction generates dystectic CaSiO3, Ca3Si2O7, flying dust fusing point is effectively improved, flying dust is reduced and coheres
Heating surface avoids coking and slagging；Gangue assists Ca (OH)2Gu sulphur：Inhibit CaSO under high temperature4It decomposes, it is steady to be formed simultaneously high fever
The double salt of qualitative calcium sulfate, calcium oxide and aluminium oxide, covering, package calcium sulfate surface, inhibits calcium sulfate to decompose, further
Play solid sulphur, desulfidation.
2. gangue fixed base metallic potassium, Ca (OH)2Gangue is assisted to fix potassium.
Reaction principle is as follows：
Al2O3(s)+2SiO2(s)+KCl(g)+H2O(g)→2KAlSiO4(s)+2HCl(g)；
Al2O3(s)+4SiO2(s)+2KCl(g)+H2O(g)→2KAlSi2O6(s)+2HCl(g)；
Ca(OH)2(s)+2HCl(g)→CaCl2(s)+2H2O(g)。
