The front tube plate of the back-combustion chamber is the most severe part of the environment in the operation of the three-return boiler. Due to the long-term interaction between high and low temperature alternating thermal stress, it is easy to cause thermal fatigue crack at the pipe end, which is the most in the three-return structure boiler. A place where problems are easy to occur.
Based on years of research experience on boilers, FANGKUAI has developed a set of specific measures to treat the cracking of the front tube sheet of the back-fired chamber, effectively reducing the risk of cracking.
1. The use of the edge-trimming ceramic tube with good temperature resistance and heat insulation effect to protect the weld seam of the front tube sheet of the back-fired chamber is not only simple in construction but also in quality.
2. Refractory cement is laid in many places at the entrance of the pipe to effectively reduce the radiation and erosion effects of the smoke.
3. The length of the pipe extension pipe is set to 3 mm long to reduce the smoke scouring effect.
4. The manufacturing process is carried out by first expanding and then welding and then re-expanding to effectively eliminate the gap between the pipe and the pipe hole.
