Abstract:

In order to improve the quality of boiler seal welded fins in power plant and fin cutting process, achieve green construction, the operation adaptability of plasma cutting equipment was technically improved and applied in engineering practice. The comprehensive technical and economic analysis was carried out on plasma cutting method and oxygen-acetylene flame cutting method. The results show that the quality and efficiency of plasma cutting is superior to that of oxygen-acetylene flame cutting, and its cost is much lower than that of oxygen-acetylene flame cutting. Plasma cutting can replace the oxygen-acetylene flame cutting as boiler fins cutting method, which is worthy of popularization and application in similar power plant construction.

Key words: power plant boiler construction, fin cutting, plasma cutting, oxygen-acetylene flame cutting
