    The boiler air cap involves many conditions and factors such as the original air distribution plate of the boiler, the opening ratio of the designed air distribution plate, the air distribution plate resistance, the air outlet speed of the air cap hole, and the rated head of the blower. According to the design of different furnace types, and referring to the resistance of the air distribution plate before the transformation and the actual operating conditions, it is generally necessary to ensure that the resistance of the air distribution plate is appropriate. If the design resistance is too large, the power consumption of the fan will be increased. Affecting the quality of fluidization, there are many cases where the critical fluidized air volume is too large or not fluidized because the resistance of the air distribution plate is too low.

Many friends know that the bell-type boiler hood is composed of a cap body, an inner sleeve and an air duct. The cap body and the air duct are threaded. The cap body is made of wear-resistant heat-resistant steel. The other parts are heat-resistant. Pipe processing. This hood can effectively avoid slag leakage and is easy to replace. The bell cap-type hood experienced local blockage, coking, abrasion, and falling off during actual operation, which seriously affected the safe operation of the boiler.

    In addition, whether the layout of the hood in the hearth and the structural design of the hood itself is fair, and the material formula of the hood are critical to the life of the hood and the safe use of the equipment. Furthermore, in order to reduce the cost of reconstruction and make the reconstruction simple and easy, it is also necessary to consider the layout of the hood after the reconstruction. Whether to re-open holes in the air distribution board should generally be based on the original opening.

    Boiler hood metal maintenance layer: The surface of iron products is plated with a layer of non-corrosive metal or alloy. However, the metal maintenance layer used on iron products should generally use hot-dip galvanizing. Due to the professional degreasing and rust removal before plating of the workpiece and high-temperature dipping in a zinc melt at 440 degrees Celsius, its coating can cover many defects and gaps and prevent future rust (especially suitable for outdoor ironwork antirust ) And has excellent adhesion properties. Such as the surface is black, blue, phosphate treatment, etc.
