The most common economizer has carbon steel tubes from 30 to 50 mm outer diameter. Transversal and longitudinal spacing is almost the same, from 50 to 150 mm. Because of low temperatures, the heat transfer coefficient in economizers tends to be small. To increase the heat transfer surface the economizer tubes can be made with fins.
Bare tubes are typically utilized in order to minimize ash fouling, but some boiler OEM's design their economizers with finned tubes, either spiral or long finned. 4 HDB can produce economizer elements with either bare, spiral finned, or long finned tubes, and if you prefer, re-design your unit to one of the other tube-types.
It has been widely used at heat exchanger pipe and tubing services, tube exchanger bundle, high pressure boiler, economizer, super heater, petrochemical industry pipes, etc.[plate]Seamless Steel Pipe and Tube, Carbon Steel Seamless Pipe[steel]Applies to water, air, heating steam, gas and other low pressure fluid delivery ASTM A53 98, JIS G3452
HDB Grade A manufacture industrial boiler spiral finned tube economizer is a heat exchanger device that captures the "lost or waste heat" from the boiler's hot stack gas.Cheap price and good quality spiral finned tubes 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.
