The economizer and its circulating system should be designed so as to avoid any serious water hammer caused due to steaming in the economizer tubes. The economizer tubes can be seamless material. The economizer should be of a continuous loop drainable type and arranged for the upward flow of water and downward flow of flue gas.
2.2. Tubes Operational Facts New A210 grade A1 (for LTR and ITS) and A210 grade C tubes (for economizer) were fitted in the boiler unit in July 2003. The tubes' inner radius and wall thickness are detailed in Table 1. Table 1. Tube
Boiler accessories economizer Construction: Economizer consists of large vertical steel or cast-iron pipes. Hot flue gases from the boiler pass over the vertical tubes. Working: The feedwater is preheated before it enters into a boiler. Heat transfer takes place
