A kind of coal-burning boiler based on coating technology
Technical field
The utility model relates to heater, is specially to utilize coating technology to carry out a kind of power economized boiler of power-save operation and maintenance.
Background technology
One of country's " Eleventh Five-Year Plan ten big emphasis energy conservation project implementation guidelines " is exactly the boiler energy-saving transformation, and enterprise only depends on buying new equipment and inadvisable, has increased the investment burden of enterprise on the one hand, and new equipment may not necessarily effectively solve problem of energy saving on the other hand.The reducing energy consumption of present coal-burning boiler concentrates in the structure design of equipment mostly, and the thermal efficiency that promotes coal-burning boiler from the structure design is very difficult, and this can cause some shortcoming on improvement cost, energy-saving effect and the security performance.Situation that the more important thing is coal-burning boiler oxidation, efflorescence, slagging scorification still can't solve.
The utility model content
The technical problem that the utility model solved is to provide a kind of coal-burning boiler based on coating technology, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of coal-burning boiler based on coating technology, in original boiler foundation, transform, by at stove tube, the boiler tube of boiler and on the burner hearth refractory material, coat different coating materials and form coating system and realize, wherein be coated with nanometer high temperature heat absorbing coating on boiler stove tube, the boiler tube, its coating layer thickness is 0.2mm; The burner hearth inner surface scribbles the energy-saving coating that nano material is formed, described energy-saving coating is three layers, be respectively nanometer high-temperature infrared reflectance coating, nanometer high temperature insulating heat insulation coating and nanometer high temp, infrared radiation coating from inside to outside, wherein the coating layer thickness of nanometer high-temperature infrared reflectance coating is 0.1mm, the coating layer thickness of nanometer high temperature insulating heat insulation coating is 1mm, and the coating layer thickness of nanometer high temp, infrared radiation coating is 0.2mm.
The coating material of described nanometer high temperature heat absorbing coating is ultra-fine nano particle; these particles are penetrated in the boiler stove tube that is corroded, the boiler tube tissue; formed the 3 D stereo inorganic network structure with it; the spot corrosion of boiler stove tube, boiler tube can be repaired; form the high temperature resistant heat absorption protective layer of hard and compact; stop thermal-flame and gas cyaniding boiler steel, prolong the service life of boiler steel in the stove.
Energy-saving coating system on the described burner hearth refractory material is made up of the material with high IR emissivity, these materials are formed a very fine and close inorganic network structure, the infrared emittance of refractory material is improved greatly, reduce simultaneously its porosity greatly, thereby reach the effect of infra-red radiation and heat-insulation and heat-preservation, thereby effectively reduce equipment energy consumption.
Beneficial effect: the utility model can make not efflorescence of refractory material, not slagging scorification in the boiler in energy-conservation, makes boiler stove tube and not oxidation of boiler tube, not slagging scorification, has prolonged the service life of boiler effectively.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the stove tube and the boiler tube of a kind of coal-burning boiler based on coating technology of Fig. 1, Fig. 2, boiler stove tube 1 and boiler tube 2 are boiler steel, and its outside evenly scribbles nanometer high temperature heat absorbing coating.
In addition, on the burner hearth refractory material, scribble the energy-saving coating that nano material is formed, schematic cross-section referring to the energy-saving coating of Fig. 2, mainly comprise three layers, outwards be respectively nanometer high-temperature infrared reflectance coating 4, nanometer high temperature insulating heat insulation coating 5 and nanometer high temp, infrared radiation coating 6 from the furnace wall 3 of body of heater, they have been coated on the endosexine of furnace wall 3 equably.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
