Product description
To be manufatured by the advaced manufacturing technology and strict process, the complete test methods and high technology coil production line. With the auto arc to butt tubes improve the working efficiency and keep the quality stable, teh advanced small R heading double direction and double R bender to make the products diversified to improve the production efficiency and quality.
Introduction
In boilers, Economical low installation costs better performance boiler economizer for CFB boiler are heat exchange devices that heat fluids, usually water, up to but not normally beyond theboiling point of that fluid. Economical 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. Better performance boiler economizers 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 (thefeed water).
| Boiler Efficiency of Condensing Economizers | ||
| System | Combustion Efficiency@4% ExcessO2(%) | Stack Gas Temperature°F |
| Boiler | 78 to 83% | 350 to 550 |
| -With Feedwater(FW)Economizer | 84 to 86% | 250 to 300 |
| -With FW and Condensing Economizer | 92 to 95% | 78 to 150 |
Accessory
The boiler economizer acts as a waste heat recovery device, ensuring that this heat does not go unused. Instead, the heat is used to essentially preheat the water, so that less heat is required to bring the water to a temperature high enough to make steam.
