CFB boiler is a new type of environmentally friendly boiler, which needs to use a lot of refractory materials to withstand harsh environments such as high temperature, high pressure and corrosion. The following are the key points and precautions for CFB boiler refractory construction:
1. Material selection: It is very important to choose the appropriate CFB boiler refractory material. It is necessary to consider the chemical composition, physical properties, wear resistance and erosion resistance of materials to meet the needs of different positions of CFB boilers.
2. Design plan: Before the construction of CFB boiler refractory materials, it is necessary to determine the details of the construction plan, construction drawings and construction technology according to the design plan to ensure the safety, quality and efficiency of the construction process.
3. Surface treatment: Before construction, it is necessary to carry out surface treatment on the inner wall of the CFB boiler to remove impurities such as dirt and carbon deposits, so as to ensure the adhesion and firmness of the construction materials and the inner wall.
4. Construction method: The construction of refractory materials inside the CFB boiler mainly includes various methods such as shaping, formwork pouring, pressing and painting. It is necessary to choose the appropriate construction method according to different locations and details.
5. Construction quality control: In the construction process of CFB boiler refractory materials, the quality of each link needs to be strictly controlled, including the mixing ratio of materials, surface treatment quality, construction thickness and compactness, etc., to ensure that the quality of the final product meets the requirements .
6. Safety protection: During the construction process, it is necessary to do a good job of safety protection, including wearing labor protection supplies, standardizing the operation process and paying attention to the hygiene of the construction site, etc., to ensure the safety and health of the construction workers.
In a word, CFB boiler refractory construction is a complex work, which requires comprehensive consideration and management from multiple aspects such as material selection, design scheme, surface treatment, construction method, quality control and safety protection, so as to ensure the quality and safety of the final product. Effect.
