Boiler Accessory Spiral Finned Tube Economizer for steam boiler
Boiler accessory spiral finned tube economizer for gas oil boiler is a heat exchanger device that captures the "lost or waste heat" from the boiler's hot stack gas. Boiler accessory spiral finned tube economizer typically transfers this waste heat to the boiler's feed-water or return water circuit, but it can also be used to heat domestic water or other process fluids. Capturing this normally lost heat reduces the overall fuel requirements for the boiler. Less fuel equates to money saved as well as fewer emissions - since the boiler now operates at a higher efficiency. This is possible because the boiler feed-water or return water is pre-heated by the economizer therefore the boilers main heating circuit does not need to provide as much heat to produce a given output quantity of steam or hot water. Again fuel savings are the result. Boiler accessory spiral finned tube economizers improve a boiler's efficiency by extracting heat from the flue gases discharged.
It is made of spiral finned tubes, inlet header, outlet header, elbow and other supporting material.
Spiral finned tubes are in-line arrangement or staggered layout, water in the pipe.
Due to the expanded heat transfer area, economizer tube row number decreases, thus reducing the possibility of the welding work and solder joint leakage, improve the safety and reliability of the pressure parts Heat transfer condition in the same conditions, its weight is lighter, about 70% of the light tube economizer, the materials about 45% of the light tube economizer;
3) Lower contact resistance
4) Higher Stability
5) Anti- dust
