ECONOMISERS AND RECUPERATORS

• Economiser are used for heat recovery from the flue gases.
• Efficiency is depend on where the system is condensing and non-condensing.
• These systems are paid to capital cost in few years. Their operations are free from additional supplementary power.
• Economisers can be fed hot water which plant requirement, without additional hot water boiler.
• Boiler efficiency can be increased when used for heating fed water to boiler
• Particularly economisers are used within solid fuel system can be used for primary and secondary combustion air heating as heat recovery unit which name is recuperator
• Decreasing flue gas temperature by 20°C by heat recovery saves fuel as much as 1%.
• Ecomomisers are manufactured as smoke-tube, finned tube or stainless steel tube design, depending on the system requirements.
