Why do we use a bank tube in a boiler? - Quora

Gases enter the Boiler bank where the heat exchange takes place between boiler bank tubes and flue gases. Boiler bank tube helps to recover the heat energy within the flue gases and Boiler bank tubes convert the water coming out from economizer to saturated steam by exchanging the heat b/w flue gas.
