Mar 01, 2019 · In the actual long-term operation of coal-fired power plants (CFPPs), the degree of pollution of the heating surface increases with the boiler running time, so that the exhaust gas temperature of the long-term operation boiler is higher than the design temperature of 10–30 °C.
Economizers designed for natural gas only, would likely plug-up if installed on a coal boiler and would face increased risk of corrosion if installed on an oil-fired boiler. Some units are designed to keep the flue gases above condensation temperature, and others are made of materials that resist the corrosive effect of condensed flue gases.

The coal pulverizers are the heart of a pulverized coal–fueled boiler. About 75% of the opportunities for improvements in tuning are with the coal mills, primary airflow, and fuel line balancing.
The Economizer is a device installed in the lower part of the flue of the boiler to recover the waste heat of the exhausted flue gas, and the boiler feed water is heated to the heated surface of the saturated water under the steam drum pressure, because it absorbs the heat from the high temperature flue gas, and cools down the exhaust gas
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 ( flue gas ) and transfer it to the boiler feedwater.
For large boiler or small boiler, economizer is a crucial part. Why boiler economizer is necessary?
