1. Boiler economizer is part of the heating area of boiler, to heat the feed water into saturated water inside the flue ducting, due to its absorption of low temperature flue gas heat, the economizer reduces the exhaust temperature of flue gas, save the energy, improve the efficiency, so called as economizer. Economizer steel tube type is without pressure limit, can be used as a boiling type, generally made by the outer diameter of 32 ~ 51 mm carbon steel tube.Sometimes in tubes with fins and fin, to improve the heat transfer effect. Boiler economizer is used for recovery of waste heat from boiler.

2. Boiler H finned tube economizer is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form ins positive shape much like letter "H", so called H-fin tube. H finned tube economizer widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.
