The economizer can be installed at the rear of exhaust gas stovepipe to recovery exhaust gas heat,increase the electricity output,lower the coal consumption
spiral finned tube economizer is a new and efficient heat transfer equipment, which is a good solution to the light tube economizer because of badly worn, short life and other shortcomings.
Technical Diameters:
| specifications of finned tube | unit(mm) |
| Bare pipe(od) | 25-165 |
| bare pipe(thick) | 2-8 |
| finned thicks | 0.6-3.0 |
| finned height | 5-30 |
| finned tube thread pitch | 5-30 |
| finned tube length | </=12000 |
| Remark |
1.Other specifications outside the table should be proposed, it is negotiable. 2.Generally speaking, the height of the fin <=1/2d 3 The spiral finned tubes produced by our company are manufactured according to the principle:JB/T6512-92 DG1020-97 |
Features of whole sale spiral finned tube economizer for cfb boiler:
1, material composition
It is made of spiral finned tubes,inlet header,outlet header, elbow and other supporting material.
2, the structural arrangement
Spiral finned tubes are in-line arrangement or staggered layout, water in the pipe.
3, Features
heat transfer area can be greatly extended, reducing the volume and angle fittings, enhanced heat transfer.
hard fouling Clogging: As gas flows through the finned tube forming the boundary layer, resulting in the vortex.
adapting to wide temperature, high pressure;impact resistance low flue gas resistance
Accessory:
It is composed of many thin wall steel tubes and tube sheets.
The material:Q215,Kaodeng steel 09CuPcRnI-A,ND steel,S.S steel
The tube shape:round,oval,spiral groove,fin
Application:
In boilers, spiral finned tube economizer 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).
