  The cfb boiler is an efficient, environmentally friendly, clean boiler, generally used in China's major thermal power plants. However, due to the characteristics of cfb boiler itself its water-cooled wall and other furnace heating surface is easy to wear, with instability can cause huge economic losses and personnel injuries to thermal power plants. If we can completely cure the cfb boiler water-cooled wall wear problem, not only can greatly improve the economic efficiency of power plants, but also can promote the wider application of cfb boilers.

  cfb units in China's thermal power industry has achieved relatively good results, but its water-cooled wall wear problem is still very serious, plagued by major thermal power companies. cfb boiler water-cooled wall wear is mainly because the boiler in daily operation, the presence of a large number of high-speed movement of material particles in the furnace chamber on the water-cooled wall for continuous cutting and scouring, until the water-cooled wall breakage led to leakage burst tube. Especially the harder the fuel particles, the greater the movement speed, the greater the concentration of flue gas in the furnace chamber, the cutting and scouring force on the water-cooled wall will become greater and greater, and the wear and tear will become more and more serious.

  According to our research and analysis, cfb boiler water-cooled wall wear will also be related to the actual daily operation of the boiler, which is different according to the actual situation of the power plant. Although the optimization of the boiler daily operation program can reduce the water-cooled wall wear, but this can not fundamentally solve the cfb boiler water-cooled wall wear problem, the need to collect effective anti-wear technology to assist, completely solve the water-cooled wall wear problem.

  At present, the most mainstream anti-wear thorough grille anti-wear technology on the market is first introduced by our company, and first in the power plant practice application. Breakthrough the traditional passive anti-wear way, grille anti-wear technology is a kind of active anti-wear technology, from the fundamental completely solve the water-cooled wall wear problem. At present, it has been almost 8 years since the first boiler applied the grille anti-wear, and no more water-cooled wall wear caused by leakage and burst pipe problems in these 8 years.

  After a lot of practice shows that the use of grille anti-wear technology can significantly reduce the water-cooled wall wear, completely eliminate the occurrence of boiler water-cooled wall wear leaks, burst tubes, protection area for several years without welding replacement, saving a lot of maintenance costs and maintenance time.
