       With the continuous progress of modern industry, in many large-scale power plants, power plant boiler products will be applied in the process of engineering construction. Medium and large boilers, which are also one of the important thermal equipment.There are mainly front wall layout, front and back wall hedging layout and four-corner layout. According to the layout, it can be divided into swirl burner and once-through combustion. Then, what are the characteristics of power station boilers?Let’s take a look at it together:
       you will find that the characteristics of power station boilers are relatively obvious. There are mainly two types of pulverized coal boilers and circulating fluidized bed boilers, both of which use low volatile and high ash fuels, and the pulverized coal pipelines are very well arranged. Simple, and the four-corner arrangement is to arrange the DC burner at the four corners of the furnace. The center line of the entire nozzle is tangent to an imaginary circle in the center of the furnace. The layout of the air duct is more complicated, but the combustion is relatively stable. It is suitable for lignite, bituminous coal and lean coal. Multiple fuels.
       In many thermal power plants, power station boiler equipment plays an important role. The common ones are inverted U-shaped, tower-shaped and box-shaped, depending on factors such as fuel characteristics, boiler capacity and steam parameters. Among them, inverted U-shaped is suitable for various The capacity of boiler and fuel is mainly because the height of the boiler is lower than other furnace types, the heating area is very wide, and it is widely used. Fans and dust removal equipment can be placed on the ground, but the area is large.
       There is also a tower-type power station boiler, which has no turning flue, which can reduce the local wear of the fly ash on the heating surface, and has a relatively small footprint, which is suitable for boiler equipment burning ash-rich bituminous coal and lignite.In addition, the box type is suitable for oil and gas boilers with large capacity, the overall structure is compact, and the floor area is small, especially the connection between the boiler and the steam turbine is more convenient.
