Specification
In boilers, NDT high frequency welding fin tube boiler economizer for water heating are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Fin tube boiler economizers are so named because boiler economizers for water heating 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. High frequency welding boiler economizers are a device fitted to a boiler which saves energy by using the exhaust gas from the boiler to preheat the cold water used to fill it (thefeed water).
Features of fin tube boiler economizers
1. newly designed economizer with higher efficiency.
2. cast iron material which could resisit for higher temperature.
3. take fully use of the exhause heat from the boiler, increase the feeding water temperature, which could help to imporve the boiler efficiency.
4. with long working life.
5. capacity range from 0.5t till to 40t.
Application
NDT high frequency welding fin tube boiler economizers for water heating are tube heat exchangers located in the top section of a boiler. steam boiler economizers raise the feedwater temperature to slightly below saturation temperature. fin tube boiler 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. Boiler economizers preheat the cold water used to fill water wall panels.
