Economizers are basically tubular heat transfer surfaces used to preheat boiler feed water before it enters the steam drum. By recovering the energy from the flue gas before it is exhausted to the atmosphere this performs a key function in providing high overall boiler thermal efficiency. Boiler economizer is a heat exchanger device that captures the "lost or waste heat" from the boiler. The economizer typically transfers this waste heat to the boiler's feed-water or return water circuit. Capturing this lost heat reduces the overall fuel requirements for the boiler. The boiler feed-water or return water is pre-heated by the economizer, therefore the boilers main heating circuit does not need to provide so much heat to produce a given output quantity of steam or hot water.
Compared to other kind of economizer, spiral finned economizer has larger heat-transferring area, so that more heat can be transferred under the same heating condition.
Main Features:
Large heating area, higher heat transfer rate
Compact structure, cost effective
Convenient installation, easy to clean
Stronger construction, better tube protection
