Description
Technical field
The present invention relates to energy-saving modified coating of a kind of boiler water wall and preparation method thereof, belong to the inorganic fire proof material field.
Background technology
Energy-saving and emission-reduction are one of national strategies of Chinese national economy Sustainable development.Classify boiler energy-saving as the energy-saving and emission-reduction major fields beginning from Eleventh Five-Year Plan country in period, the power-saving technology of relevant industrial boiler and station boiler emerges in an endless stream.
Point out that the energy structure of China still mainly relies on coal in the long term in country's 2005～the year two thousand fifty ENERGY PLANNING, and Industrial Boiler and station boiler account for 80% of coal consumption amount.In recent years; Continuous anxiety along with coal supply; The coal source of thermoelectricity enterprise is also more and more unstable with quality; Actual combustion coal and design coal difference are also increasing, cause safety-problemss such as burning state instability, overtemperature of tube wall, coking aggravation, non-programmed halt outstanding, and the economy of producing simultaneously descends; Known other power-saving technologies still fail to address the above problem at present.
The actual motion of boiler is a whole circular process, not is to be exist singly on the question essence that wherein a certain link occurs, but shows that problem has appearred in the balance of whole circular.So single part or triangular web that boiler is transformed in simple dependence can not solve the problem that boiler exists, and are only the key that solves the many challenges of boiler plant and adjust boiler whole circular process and make it more to level off to optimal operational condition.
Present domestic correlation technique patent is mainly used in the temperature lower arcola or Industrial Stoves, and the coating that generally is used to be coated on the non-metallic material is main, but also not in hot conditions and be coated in the technology of life-time service on the metallic substance.Its material of coating that Industrial Boiler and water-cooling wall of power boiler are used will overcome following problem:
1 coated material under low temperature and hot conditions with the attachment issue of boiler water wall steel.

Below further prove the performance of the energy-saving modified coating of boiler water wall through actual test.
1, case 1
Ltd of XXX hot working research institute tests this technology.Test result shows: " through test; the water cooling tube that is covered with the Fa Ermaite energy-saving material is superior to contrast pipe 7.89% to the hot average absorption effect of hyperthermia radiation; the Fa Ermaite energy-saving material is applied to boiler water wall, can improve heat exchange effect in the stove, should have influence on exhaust gas temperature; and then improve boiler thermal output, advise using at station boiler.
This test shows: after applying the energy-saving modified coating of boiler water wall of the present invention, can improve water wall and absorb photothermal ability in the stove.The water wall tube heat absorption increases, and boiler duty also can correspondingly increase.Simultaneously, heat loss due to exhaust gas (heat of waste) also can correspondingly reduce, thereby improves boiler thermal output, save energy.
2, case 2
XXXX Guangdong can electric power development company can generate electricity in Guangdong to this technology and compare the thermo-efficiency test before and after the #1 stove transformation of XX power plant of Ltd; And energy-saving effect made following evaluation: " DG420/13.7-II2 D-type boilerD; under operating mode 1 (101KW) and two kinds of operating mode situation of operating mode 2 (132KW) carries out boiler thermal output contrast test before and after the reducing energy consumption.The imperfect combustion loss Q4 of machinery is 5.75% and 4.10% before transforming; Be 4.25% and 3.44% after the transformation, reduced by 1.5% and 0.55%; Heat loss due to exhaust gas Q2 is 5.38% and 5.82% before transforming, and is 5.18% and 5.29% after the transformation, has reduced by 0.2% and 0.53%; Thereby realized the significantly raising of boiler thermal output generally, under two operating modes, improved 1.72% and 1.07% respectively ".
This test shows: after the energy-saving modified coating of this coating invention boiler water wall, reach the effect that reduces funnel temperature and strengthen coal dust after-flame degree really.Carrying out under two kinds of operating modes under the strictness test, boiler thermal output all improves significantly, and has verified that also the present invention's thermo-efficiency in station boiler is used improves this actual effect of 1%～3%.
Simultaneously, XX boiler of power plant operating management department also to this technology for preventing coking, improve boiler operatiopn security aspect and affirm; Coking was serious before the #1 stove was transformed; Operate steadily after the transformation, blowing out fed to boiler thorax is observed, and does not have coking on the furnace wall cooling basically.And the #2 stove that the same terms moves down is serious because of coking, and the bulk coke button falls, and causes non-programmed halt 3 times.
These practical situation have fully shown coating of the present invention in the effect that prevents aspect the boiler coke, and the application of further having proved coating of the present invention can improve the boiler operatiopn security.
3, case 3
Following evaluation is made to this technology by the thermoelectric ltd of XXXXXX before and after #2 boiler (model SG-1025/17.5-M729) is transformed: " this improvement project to the boiler overall operation security played active effect; the effect that boiler is prevented coking is very obvious; the also suitable high temperature corrosion that has slowed down water wall; and enlarged to mix and burn the space, under the situation of going into stove coal variation, continues to ensure the safe operation of boiler.Simultaneously, this improvement project has also been brought certain energy saving economy benefit.Transform the back funnel temperature and decrease, again, suphtr desuperheating water input all has minimizing.Boiler efficiency also improves.”
The thermoelectric ltd of XXXXXX belongs to local construction, and this coating real area only is 25% of the complete construction area of water wall.But this small portion coating has still obtained obvious effects: prevent that the coking effect is obvious; After applying this coating, water wall high temperature corrosion attenuate degree be not applying coating 1/3, effect is obvious.Simultaneously, only the coating of this small portion to reducing funnel temperature, reduces suphtr, reheater desuperheating water flow, has also produced effect,
In a word, can find out that from each the case contrast of above reality the energy-saving modified coating of this boiler water wall has following advantage:
1 reduces mechanical imperfect combustion loss, improves coal-fired after-flame degree.
2 improve the water wall caloric receptivity, reduce heat loss due to exhaust gas.
3 prevent coking, delay high temperature corrosion, improve boiler operatiopn safety.
4 improve boiler thermal output, realize energy-saving and emission-reduction.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
