wide range of customized spiral fin tube in boiler economizer
Specification:
Customized ISO TUV ASME standard better performance spiral fin tube for boiler economizer is the most widely used of the spiral finned tube, widely used in electric power, metallurgy, cement industry preheating collection and petrochemical industries. Carbon steel or stailess steel spiral fin tube is welded steel strip coil pipe at the same time, using high-frequency currents of the skin effect and proximity effect of steel tube, and surface heat until melted in the plastic state or steel strip coil, the complete welding under certain pressure. This kind of high frequency welding as a solidphase welding. It with Mosaic, brazing (or whole galvanized) method, whether in product quality (fin of weld rate is high, of 95%), or the productivity and automation degree, are more advanced.
Application
In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water).
