Description
Technical field
The present invention relates to fire resisting material field, more particularly to biomass boiler anti-slag coating.
Background technology
Some plastic materials, rubber material all can be there is in biomass boiler in all there is clogging problems, i.e. biomass fuel
The goods of material, such as plastic bag, tire debris, such plastic material, the goods of elastomeric material enter in combustor from charging aperture
Burning, can form jelly after burning, these jellies are easily attached to be positioned on the combustor bottom surface below charging aperture, impact
The efficiency of combustion of subsequent bio matter fuel, after biomass boiler quits work, the cooling slagging scorification of this type of jelly be attached to be positioned at into
On combustor bottom surface below material mouth, it is not easily cleaned, slagging scorification can be caused the most in the past to get more and more, cause the biomass boiler cannot
Normal work.
Summary of the invention
For above-mentioned technical problem, it is an object of the invention to provide biomass boiler anti-slag coating, it is to avoid biomass boiler
Inwall slagging scorification.
In order to solve above-mentioned technical problem, the present invention provides following technical scheme:
Biomass boiler anti-slag coating, including A basic material and B anti-slag coating；
Described A basic material, is made up of following raw material according to parts by weight, high alumina micropowder 5 ~ 10 parts, 36 ~ 60 parts of corundum,
Carborundum 10 ~ 20 parts, 3 ~ 8 parts of Yixing mud, potassium feldspar 2 ~ 12 parts, kyanite 1 ~ 5 part, silica flour 2 ~ 8 parts, raw material stirring is uniform, adds
Entering Ludox bonding agent, beater is beaten to mix and is uniformly become pasty state；
Described B anti-slag coating, is made up of following raw material according to parts by weight, carborundum 45-90 part, silicated graphite 1 ~ 5 part, gold
Belonging to silicon 1 ~ 5 part, silica flour 3 ~ 10 parts, raw material stirring is uniform, adds Ludox bonding agent, and beater is beaten to mix and uniformly become pasty state.
Described carborundum particle diameter is not more than 3000 mesh.
The biomass boiler anti-slag coating that the present invention provides, basic material mainly plays the effect of double faced adhesive tape, it is possible to have
Combining with former furnace wall of effect, increases furnace wall intensity, simultaneously again can be with the B affine combination of anti-slag coating.Make owing to the addition of Yixing mud
For agglutinant, so just can sinter at middle temperature state, make anti-slag coating be bonded in firmly on furnace wall, add the wear-resisting of furnace wall
Anti-slag intensity.
The biomass boiler anti-slag coating that the present invention provides, utilizes the difficult infiltration of carborundum and superpower anticorrosion properties.
In compound, add the high-purity silicon carbide micro-powder less than 3000 mesh, add consistency and the permeability resistance of coating.Add
Powerful antioxidant silicated graphite, silicated graphite at high temperature generates fine and close Si island glass phase with oxygen reaction, prevent oxygen and
The contact of carborundum, prevents carborundum life-time service oxidized under high temperature oxidative atmosphere.Silica flour is agglutinant, is burnt by high temperature
Knot makes former furnace wall add wearability and corrosion resistance, the eutectic produced under effective concentrated wear stoping furnace wall and inner operating
Thing is to the infiltration erosion of furnace wall and slagging scorification, with Ludox as bonding agent, coating can be made to form fibrous reticular structure, increase strong
Degree.And can be effectively improved service life of resistance to material and boiler runs the time reliably, thus reduce the consumption of resistance to material and blowing out is clear
Slag number of times.
A basic material and B anti-slag coating must separately produce, it is impossible to batch mixing.Finished product Plastic Drum is packed.
During use, first coating A basic material, is coated with B anti-slag coating.
The biomass boiler anti-slag coating that the present invention provides, preparation technology is simple, and the material intensity height that material coating is formed is suitable for
Use under biomass boiler operating mode, be effectively improved biomass boiler Slagging.
