Economizer
An economizer is a heat recovery system that recovers the waste heat from hot flue gases discharged from the boiler’s flue and uses it to preheat the boiler feedwater. As the preheated water enters the boiler, less fuel is consumed; the flue gas temperature decreases, and boiler efficiency increases significantly. Manufactured from pipes capable of withstanding high temperatures and pressures, the unit is sized according to boiler capacity and can be adapted to existing systems. It is an efficiency investment that pays for itself in a short time through lower emissions and reduced operating costs.
ECONOMIZER (Flue Gas Heat Recovery System)
An economizer is a heat recovery system that recovers the waste heat contained in hot flue gases discharged from the boiler’s flue into the atmosphere and uses it to preheat the boiler feedwater. It consists of a heat exchanger designed so that the flue gases and feedwater exchange heat across the tube surfaces without mixing. A significant portion of the heat that would normally be lost through the flue is recovered in this way and transferred to the water entering the boiler.
When feedwater enters the boiler at a higher temperature, it reduces the amount of fuel required to vaporize the water. Using preheated water instead of cold water allows the boiler to produce the same amount of steam or heat while consuming less fuel. As a result, fuel consumption decreases, flue gas temperature drops, and a significant increase in boiler efficiency is achieved. As a general rule, every increase in feedwater temperature translates directly into fuel savings for the facility.
The economizer is sized according to the boiler’s capacity, flue gas flow rate, and temperature; it can also be adapted to existing boiler and flue systems. Manufactured from pipes resistant to high temperatures and pressures, the unit stands out as an efficiency investment that pays for itself quickly in the boiler room thanks to its robust construction and long service life.
