What are the advantages and disadvantages of circulating fluidized bed boilers!

       Many industrial production in China can not be separated from boiler equipment, especially in many chemical plants, power production enterprises will be applied to a variety of boiler equipment. In the past, the application is the traditional pulverized coal furnace boiler, with the continuous development of industry, human awareness of environmental protection is more and more strong, many enterprises are gradually applied to the circulating fluidized bed boiler. Its capacity is relatively large, more efficient, environmentally friendly and clean making it more widely used.

　　Although many enterprises are gradually replaced by circulating fluidized bed boilers, so what are the advantages of circulating fluidized bed boilers in the end!

　　Circulating fluidized bed boiler coal feeding method according to the coal feeding position to be divided into three kinds of coal feeding before the furnace, coal feeding after the furnace and coal feeding after the furnace, different types of circulating fluidized bed boiler equipment characteristics are different.

　　The characteristics of circulating fluidized bed boiler are more obvious, the first two types of coal feeding method is not uniform, while the coal feeding before and after the furnace is more uniform, but the coal conveying system is more complex and difficult to maintain, because the coal feeding mouth is in negative pressure, coal flows into the furnace by its own gravity, the structure is simple, and plays an important role in many chemical industries, food industries, and paper and rubber industries.

　　The fuel of this circulating fluidized bed boiler is widely adaptable and is calculated by weight, with fuel accounting for 1~3% of the bed material and the rest being non-combustible solid particles, such as desulfurizer and ash. In the whole heating process, the impact on the bed temperature is small, and the combustion of magnesium particles can release heat, combustion efficiency is relatively high, good gas-solid mixture, high fuel rate.

　　After talking about the advantages we are talking about the disadvantages of circulating fluidized bed boiler! Then you know what are the outstanding disadvantages of circulating fluidized bed boiler!

　　Circulating fluidized bed boiler more prominent problems can be divided into the following points.

　　1, the heating surface wear problem is more serious, this problem can be said to be the most prominent circulating fluidized bed boiler most affected by the smooth operation of the boiler. Boiler wear problem is a problem that can not be ignored by enterprises, at the beginning of the development of circulating fluidized bed boilers many enterprises do not pay attention to the issue of boiler wear resulting in boiler shutdown is rife.

　　2, the unit energy consumption level is relatively high, this is mainly because the circulating fluidized bed boiler has a large resistance parts such as cloth wind plate, cyclone separator, so the smoke and wind is relatively higher than the traditional pulverized coal furnace to a little.

　　3, the auxiliary equipment requirements are relatively high, if the performance of other auxiliary equipment is not good may cause the boiler can not operate normally.

　　To sum up, the circulating fluidized bed boiler equipment is very wide range of adaptation, high combustion intensity, small cross-sectional area of the furnace, load regulation range is relatively large, and can achieve comprehensive utilization of ash residue. More environmentally friendly, efficient, energy-saving more suitable for modern industrial development. Of course the disadvantages can not be ignored by enterprises, if enterprises can solve the most important anti-wear problem, the smooth operation of the boiler will be guaranteed.
