چکیده مقاله :
In professional industries have taken an interest in being more environmentally friendly, it is important that all adopt a unified standard regarding environmental preservation. In this investigating the increase in demand for electricity in the world a continuous search for new sources of energy, engineering and technology solutions. Heat recovery system generator (HRSG) is obviously a very desirable energy source, since the product is available almost operating cost-free and increases the efficiency of the cycle in which it is placed, either for steam generation or for incremental power generation. Increasing thermal efficiency while reducing energy costs is possible through the use of finned tubes for heat exchangers. Welding contact currents frequency is a variation of resistance welding which uses high-frequency properties of the welded contact surface heating elements to melt temperature, and combinations thereof by pressure. Finned tubes used a HRSG is the core facility of a combined cycle thermal power plant that recycles thermal energy from a gas turbine and creates high temperature and high pressure gas. This paper presents the technologies of environment friendly industrial fin tube boiler, with particular emphasis on high-frequency resistance welded (HFRW) finned tubes.
