What are the main hazards of circulating fluidized bed boiler wear and the significance of anti-wear

      Circulating fluidized bed boiler is now an indispensable equipment in industrial production, especially in thermal power plants, chemical plants, paper mills and other enterprises play an important role. Mainly because with the rapid development of industry, environmental problems are increasingly serious, if the enterprise production in not pay attention to environmental issues, will aggravate the deterioration of the environment, resulting in irreversible consequences.

　　Circulating fluidized bed boiler is a highly efficient, clean, energy-saving, environmentally friendly combustion technology, with the intensification of environmental protection policies, the traditional boiler is slowly replaced. Although circulating boilers are more efficient and environmentally friendly, they also have drawbacks because of their own characteristics - the problem of wear and tear.

　　Boiler wear problem for enterprises like thermal power plants is a big problem, in layman's terms, if the boiler wear problems, not timely treatment, wear will aggravate, and slowly become a small wear into a leaky tube burst and other serious safety accidents. Not only affects the economic efficiency of the enterprise, but also greatly threatens the safety production of enterprises. So for the use of circulating fluidized bed boiler enterprises, boiler anti-wear is particularly important.

　　Today, I will talk to you about what are the main hazards of circulating fluidized bed boiler wear.

　　After a number of circulating fluidized bed boiler research found that the main wear and tear is mainly in the boiler's heating surface, refractory wear-resistant materials and the damage to the wind cap of the wind plate.

　　Wear of heating surface

　　Circulating fluidized bed boiler heating surface, whether it is water pipe, gas pipe, or air pipe wear, minor wear will lead to changes in the thermal stress of the boiler, will make the boiler uneven heating, if serious will directly lead to boiler burst or heating surface leakage, the situation is serious will directly lead to boiler shutdown. Boiler shutdown means that the power plant can not generate electricity, the enterprise can not operate normally production.

　　Refractory wear-resistant material wear

　　The wear and tear of boiler refractory wear material will make the refractory wear material fall off, the boiler will leak ash, air leakage or aggravate the local heating surface wear, the refractory wear material in the furnace chamber will fall off will block the slag discharge port, causing poor slag discharge or poor fluidization, the refractory wear material in the separator will fall off will block the standpipe and affect the normal operation of the feeder.

　　Wear and tear of the wind plate cap

　　Circulating fluidized bed boiler wind plate cap wear will directly lead to uneven distribution of air in the boiler, wind cap will also appear slag leakage, long-term failure to deal with will lead to boiler coking, directly leading to serious problems such as boiler air chamber blockage.

　　These wear and tear will affect the normal operation of circulating fluidized bed boilers to varying degrees, the consequences are self-explanatory, I hope that for the use of circulating fluidized bed boiler enterprises can pay attention to boiler anti-wear, from the root to completely solve the problem of wear.
