Boiler Components 省煤器 Economizer
Ø 作用：利用锅炉尾部的烟气热量加热给水的一种热交换装置。其开始是为了降 低排烟温度，提高锅炉效率，节约燃料，因此称为省煤器
Ø 结构：管排、集箱、防磨护瓦等组成，高压以下通风梁支承，高压以上悬吊
Function: An heat exchange device that utilizes the heat from the boiler's flue gas to heat the feedwater. Initially designed to lower the exhaust gas temperature, increase boiler efficiency, and save fuel, hence it is called an economizer.
Structure: Consists of tube banks, headers, wear-resistant tiles, etc. Supported by ventilation beams below high pressure and suspended above high pressure.
