What is the function of economizer in steam power plant

A common application of economizers in steam power plant is to capture the waste heat from boiler stack gases (flue gas) 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.

TABLE OF CONTENTS RECTANGULAR ECONOMIZERS INSTALLATION

With the economizer filled, vented, and tested, the boiler may be lighted and carried at low fire to warm up and bring the system to pressure. The economizer shutoff and by-pass valves shou ld be in the full open position. As the boiler begins to pick up load, the economizer by-pass valves should be closed proportionately.

Steam Boiler: Economizer

Economizer is a heat exchanger through which the feedwater is pumped. Another flue gas heat recovery method is through the use on an economizer. The economizer heats the feedwater to improve steam boiler efficiency and reduce heat loss to the stack. The increased heat in the feedwater reduces the boilers requirement for fuel and combustion air.

Consider Installing a Condensing Economizer

A conventional feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to the boiler feedwater. For natural gas-fired boilers, the lowest temperature to which flue gas can be cooled is about 250°F to prevent condensation and possible stack or stack liner corrosion.

What is a Boiler Economizer? (with pictures)

Nov 03, 2019 · Some boilers are designed with economizers built in, while in other cases, an economizer can be fitted on after the fact. Boilers operate by heating water to make steam, and using that steam for heat or energy generation. For the most part, a boiler is fairly efficient, but there is some heat loss when the byproducts of combustion are vented.
