節(jié)能器是安裝于鍋爐尾部煙道下部用于回收所排煙的余熱的一種裝置,可以加熱鍋爐給水。由于它吸收高溫煙氣的熱量,降低了煙氣的排煙溫度,節(jié)省了能源,提高了效率,所以稱之為節(jié)能器。節(jié)能器可用于各類鍋爐。
The economizer is a device installed in the tail chimney of the boiler to recover the waste heat of the exhaust gas, which can heat the boiler feed water. Because it absorbs the heat of high temperature flue gas, reduces the exhaust flue gas temperature, saves energy and improves efficiency, so it is called economizer. The economizer can be used in all kinds of boilers.
