Description
Technical field
The present invention relates to fire resisting material fields, more particularly to biomass boiler anti-slag coating.
Background technology
All there are clogging problems in biomass boiler, i.e., can all have some plastic materials, rubber material in biomass fuel
The product of material, such as polybag, tire debris, such plastic material, rubber material product enter in combustion chamber from feed inlet
Burning, can form jelly after burning, these jellies are easily attached on the combustion chamber bottom surface below feed inlet, influence
The efficiency of combustion of subsequent bio matter fuel, after biomass boiler is stopped, the cooling slagging of such jelly be attached to positioned at into
It on combustion chamber bottom surface below material mouth, is not easily cleaned, slagging can be caused more and more in the past for a long time, cause biomass boiler can not
Normal work.
Invention content
In view of the above technical problems, the object of the present invention is to provide biomass boiler anti-slag coating, biomass boiler is avoided
Inner wall slagging.
In order to solve the above technical problem, the present invention provides following technical solutions：
Biomass boiler anti-slag coating, including A basic materials and B anti-slag coating；
The A basic materials are made according to parts by weight of following raw material, 5 ~ 10 parts of high alumina superfine powder, corundum 36 ~ 60
Part, 10 ~ 20 parts of silicon carbide, 3 ~ 8 parts of Yixing mud, 2 ~ 12 parts of potassium feldspar, 1 ~ 5 part of kyanite, 2 ~ 8 parts of silica flour, raw material stirs evenly,
Ludox bonding agent is added, beater, which is beaten, to be mixed uniformly into paste；
The B anti-slag coating is made according to parts by weight of following raw material, 45-90 parts of silicon carbide, silicated graphite 1 ~ 5
Part, 1 ~ 5 part of metallic silicon, 3 ~ 10 parts of silica flour, raw material stirs evenly, and Ludox bonding agent is added, beater, which is beaten, to be mixed uniformly into paste.
The silicon carbide grain size is not more than 3000 mesh.
Biomass boiler anti-slag coating provided by the invention, basic material mainly play the role of double faced adhesive tape, Neng Gouyou
Effect and former furnace wall combines, and increases furnace wall intensity, while again can be with B anti-slag coating affine combinations.Make due to being added to Yixing mud
So that anti-slag coating is firmly bonded on furnace wall so can be sintered in middle temperature state for agglutinant, increase the wear-resisting of furnace wall
Anti-slag intensity.
Biomass boiler anti-slag coating provided by the invention utilizes the difficult infiltration of silicon carbide and superpower anticorrosion properties.
The high-purity silicon carbide micro-powder less than 3000 mesh is increased in mixture, increases the consistency and permeability resistance of coating.It is added
Powerful antioxidant silicated graphite, silicated graphite is reacted with oxygen at high temperature generates the fine and close islands Si glass phase, prevent oxygen and
The contact of silicon carbide prevents silicon carbide long-time service from being aoxidized under high temperature oxidative atmosphere.Silica flour is agglutinant, is burnt by high temperature
Knot makes former furnace wall increase wearability and corrosion resistance, the eutectic effectively generated under the concentrated wear of prevention furnace wall and inner operating
Infiltration erosion and slagging of the object to furnace wall use Ludox as bonding agent, coating can be made to form fibrous reticular structure, increase strong
Degree.And the service life and the reliable run time of boiler of resistance to material can be effectively improved, the consumption and blowing out to reduce resistance to material are clear
Slag number.
A basic materials and B anti-slags coating, which must separate, to be produced, and batch mixing is unable to.Finished product is packed with plastic barrel.
In use, first coating A basic materials, it is coated with B anti-slag coating.
Biomass boiler anti-slag coating provided by the invention, preparation process is simple, and the material intensity height that material coating is formed is applicable in
It is used under biomass boiler operating mode, is effectively improved biomass boiler Slagging.
Specific implementation mode
Below with reference to specific embodiment, the present invention will be further described.
