1.Introduction:

Boiler economizer is a commonly used equipment in coal-fired, gas-fired, oil-fired boilers. It is usually installed at the flue gas outlet. It uses the residual heat in the flue gas to heat domestic water or boiler water. It can also be used to heat the air and promote the combustion of boiler fuel. .

2. economizer in boiler pdf Principle

Efficient heat transfer energy-saving equipment using heat transfer elements - high efficiency fins. Through heat exchange, excess heat carried in flue gas, exhaust gas or waste water can be recovered, and then other mediums, such as air or water, can be heated to achieve the purpose of energy saving and environmental protection.

Boiler square cast iron economizer in boiler pdf Characteristics:

1. Absorb the heat of low-temperature flue gas, reduce the exhaust gas temperature, reduce smoke loss and save fuel.

2. Since the feed water is heated in the economizer before entering the steam drum, the heat absorption of the feed water on the heated surface is reduced, and the economizer can be used to replace the partially evaporated evaporating heating surface.

3. The temperature of the feed water is increased. When entering the steam drum, the wall temperature difference is reduced, the thermal stress is reduced accordingly, and the service life of the steam drum is prolonged.
