The boiler needs to be started and stopped frequently during the use of the boiler. If the boiler is not maintained on time during use or the boiler is not baked before the boiler is officially started, these situations can easily lead to internal problems in the fluidized bed boiler. Shedding of building materials. In view of this situation, during the installation of the boiler, it should be configured strictly in accordance with the material ratio drawings in the construction drawings, and corresponding experiments should be carried out. The reason for this is that wear-resistant pouring materials are not very commonly used in actual construction. Therefore, do a smear experiment before smearing, and accurately grasp the mixing time of the wear-resistant pouring material and the solidification time of the material to ensure the construction quality of the entire project.
Pouring is the key to the installation and repair of the entire boiler. Before construction, the construction personnel should make templates according to the specific construction position. In the actual construction process, use wooden boards as the template. This is relatively simple. After the construction, it does not need to be disassembled. The maintenance of the ground castables is also very helpful.
It is best to use the method of integral pouring when pouring. Expansion joints should be reserved in accordance with the specifications during specific construction. This measure can prevent the boiler from being heated during operation, causing the pouring material to expand and causing delamination and shedding.
In the process of maintenance, the old materials should be cleaned up. When pouring the header, the nails should be repaired in advance. It is worth noting that the nails in the high temperature area should be made of heat-resistant steel.
In the process of construction, because some steel nails have already been removed when they are removed, the number of nails will be reduced. When the wear-resistant material is poured in a part with a small number of nails, it is easy to be placed in this part. Because the strength is not enough, it will fall off, causing local wear of the pipe.
