The steam pressure in the boiler is regulated by the Boiler Operator. This is a pressure control which senses the steam pressure and turns the boiler on and off accordingly. This control must be operationally tested. Adjust the pressure setting on the control to a pressure less than the boiler pressure (as shown on the boiler pressure gauge). The control should turn the boiler off. Restore the control setting to normal. The boiler …

Low Water Content Boilers: The Safest Boiler Design | …

Some boiler manufacturers try to approximate modulating high turndown through modular configurations, but these "modifications" cannot operate efficiently where variable steam loads occur. Below a firing rate of 50%, these so called "step-modulation" burners actually operate in an on/off mode. Their inability to operate efficiently at the minimum or mid-fire input rate decreases the boiler's operating efficiency. Steam loads rarely operate …
