Carbon Steel Economizer with Bends for Waste Heat Boiler and Power Station Boilers
Economizer Introduction
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.
