Low Temperature Carbon Steel Economizer for Waste Heat Boiler and
Power Station Boilers
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.
Boiler economizer is a device that is designed to increase the
operating efficiency of a boiler, cutting down on its operational
costs over the lifetime of the boiler.
Although the savings on any given day may be relatively small, the
impact over time can be significant; some boilers are designed with
economizers built in, while in other cases, an economizer can be
fitted on after the act.
The boiler economizer acts as a waste heat recovery device,
ensuring that this heat does not go unused.
Instead, the heat is used to essentially preheat the water, so that
less heat is required to bring the water to a temperature high
enough to make steam.
Casting iron economizer;bare tube economizer;finned tube
Economizer;spiral finned tube economizer
|Fin height||Less than 17mm|
Tube:Carbon steel,alloy steel,
1.better product quality and longer service life.
2.energy conservation and environmental protection.
3.significantly improve cycle efficiency.
The economizer can absorb the heat of high temperature flue
gas,reduce the exhaust temperature,save energy,and improve the
efficiency of boiler.
