22 BOILERS SIMPLE BOILER Principle-A boiler is a closed vessel in which steam is generated from water by the application of heat. The simple boiler is like a barrel, consisting of a cylindrical steel shell, with the ends closed by flat steel heads. It is partly filled with water and then sealed, after which a fire is started beneath it.

gas valve, igniter and blower. When a room thermostat calls for heat, the IBC starts the system circulator and blower. The IBC runs the blower to purge the boiler flue passages, then turns on the igniter and lets it warm up. After igniter warm-up, the IBC opens the gas valve, turns the igniter off, and checks for flame.
