Who has used the integral spiral finned tube economizer?

From the manufacturing process, we can know that the smoothness of the surface, the consistency of too many details, and the wear resistance of pipe fittings are definitely better than that of integral molding; To be sure, fins are easier to catch ash than smooth tubes, and without ideal soot blowing means, the thermal efficiency advantage of finned tubes cannot be maintained. The following is the application case found, hoping to help you.

The heat conduction efficiency of spiral finned tube economizer is much higher than that of smooth tube economizer. The same demand can make the volume smaller, increase the ventilation area, and bring the benefits of lower wind speed, lower pipeline wear and more thorough heat exchange. However, finned tube economizer has advantages and disadvantages, and it is easy to accumulate dust between fins, which is difficult to deal with; During the technical transformation of a 240-ton boiler in a chemical group in Henan Province, an integral spiral finned tube economizer was used to match with scq-2 high-efficiency acoustic ash remover, and good results were achieved. The application of constant cleaning SCQ sonic ash remover shows that it not only has obvious ash removal effect, but also has stable effect, which is different from steam soot blowing effect and will not damage the heat pipe (the heat loss caused by steam soot blowing is a difficult problem). 20 15 patented product SCQ-2 has the characteristics of compact and reasonable structure, large output energy and stable operation. The matching of spiral finned tube economizer and SCQ sonic ash remover can give full play to the advantage of high thermal efficiency of finned tube and prolong the life of economizer, thus meeting the requirements of thermal efficiency and operation rate, and achieving both fish and bear's paw. Therefore, it is worth recommending to boiler peers.
