Description
Technical field
The invention belongs to the boiler combustion diagnostic field, closely related with safe operation of the boiler, be specifically related to a kind of apparatus and method of on-line monitoring boiler water-cooling wall high-temperature corrosion.
Background technology
At present, all there is the situation of Actual combustion coal off-design coal in the most power plant of China, for coal resource anxiety or price reasons, mix the burning small coal mine nearby, come any coal to burn what coal, coal changes greatly and is frequent, after particularly the higher coal of sulfur content is gone into stove, causes the boiler tube wall high temperature corrosion, the quick-fried leakage of aggravation boiler tube, directly endanger safe operation of the boiler, this trend is on big capacity unit, and is particularly remarkable.
For the mechanism of high temperature corrosion, existing both at home and abroad a large amount of comparatively deep researchs.At oil exploration, exploitation and chemical field the high temperature corrosion checkout gear is arranged, but fail to realize on-line monitoring.The device that more finds no the on-line monitoring high temperature corrosion is applied to the report of station boiler.Usually, station boiler high temperature corrosion problem all is during major overhaul, finds when checking tube wall that therefore, when pinpointing the problems, high temperature corrosion has taken place tube wall, can't point out operation or maintainer in time to take measures, and causes the tremendous economic loss to power plant.
Below be retrieve with the closely-related document of the present invention:
Patent CN1506616A has proposed a kind of method of discrimination of water wall high temperature corrosion degree, this method determines to influence the principal element of water wall high temperature corrosion earlier, determine measuring condition then, measuring respectively has related parameter, adopts grey clustering method that the water wall high temperature corrosion tendency is carried out multifactorial evaluation at last.
Patent CN1657825A has proposed a kind of boiler plant that prevents the burner wall formula layout of water wall high temperature corrosion and slagging scorification, and the adjustment of arranging by boiler structure prevents high temperature corrosion.
Patent CN101021315A has proposed a kind of low NOx vortex burning device that prevents high temperature corrosion, prevents high temperature corrosion by improving burner.
Oil instrument .2005,19 (5) documents " development of the dynamic corrosion tester of SCM Based HTHP " to have introduced what be used for field of petroleum exploitation be the dynamic corrosion tester of HTHP that core constitutes with the single-chip microcomputer, specifically set forth the test philosophy of corrosion rate, the tester structural design, the temperature of dynamic corrosion tester, rotating speed control etc.
Unit is in big capacity, the evolution of high parameter direction, because it is limited that the sectional dimension of burner hearth increases, and the heat of sending into burner hearth increases greatly, cause furnace cross to increase considerably, burner region water-cooling wall temperature is too high, has accelerated the speed of high temperature corrosion, when wall temperature in 400-500 ℃ of scope, 50 ℃ of the every increases of wall temperature, corrosion rate doubles.
High temperature corrosion is relevant with the operation adjustment, for DC burner, and near the unreasonable anoxic of water-cooling wall wall that causes of air distribution, reducing atmosphere occurs, the aggravation high temperature corrosion is for turbulent burner, the excessive uncombusted coal dust that easily causes of swirl strength washes away water-cooling wall, causes the tube wall high temperature corrosion.
In addition, the SO that also generates when the stove internal combustion with coal dust of high temperature corrosion
2, SO
3Deng sour gas direct relation is arranged, these sour gas are penetrated into the tube wall metal surface, and corrosion reaction takes place, and destroy water-cooling wall.In addition, make the metal surface easily generate loose porous FeO, in the anoxic reducing atmosphere, generate a large amount of H during the high-sulfur pulverized coal friring because the interior local anoxic of stove increases temperature
2S, H
