Steam Boiler: Economizer as Supporting Instrument in Steam Boiler

The graph above shows the advantages and disadvantages of using the economizer for preheating. Clearly seen without using a boiler economizer so work efficiency of steam boiler will decrease, in the sense that without heating which is assisted by the economizer, the boiler must work longer in the production of steam and in addition boiler will require more fuel to reach the hot temperature

Tech Basics: The Role Of Economizers In Rooftop Equipment

Types Of Economizers Dry Bulb Economizer - This economizer uses a sensor to determine if outdoor air is at or below a certain temperature, usually about 55 degrees F. If the outdoor air temperature is below setpoint and there is a call for cooling, an actuator opens a damper, allowing the outdoor air to mix with the return air to provide cooling.

Economizer - Wikipedia

The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler. A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output.
