2019-2-22·Economizer is the power plant accessory/equipment which use the heat of exhaust steam to raise the temperature of incoming water in the boiler. Economizer is an accessory of boiler that recovers the waste heat from the flue gas blown out of the boiler. Thus it actually "economizes" the operational cost or in other wor ds, improves the

2014-11-24·Boiler stack economizer CONCEPT A stack economizer is an exchanger designed to recover the heat contained in the hot flue gases from boilers; the heat is transferred to a hot water system. In the case of a steam boiler, about 20% of the energy required for the burner ends up in the flue, often at high temperatures.

Increasing Natural Gas Boiler Efficiency by Capturin
2015-3-2·boiler installations use traditional economizer technology to achieve 290 degrees Fahrenheit to 300 degrees Fahrenheit stack gas temperatures and in the order of 80 percent to 82 percent overall boiler efficiency. When fuel costs were low, this heat was seen as minor. Today it is a major target for boiler system energy efficiency improvement.
Evaluating the Effect of Economizer on Efficiency o
The difference of flue gas temperature of these boilers is due to the use of additional equipment in Boiler 2. The economizer decline the flue gas temperature to about 100°C and has a remarkable effect on improving the efficiency of Boiler 2 about 7 percent compare to the efficiency of Boiler 1 that is 77.23.
