These are called FRONT-FIRED OPERATING PRESSURE BOILERS. Other ships, such as the AO-177 and LKA-113 class ships, have their burners on the top of the boilers. These are called TOP-FIRED BOILERS. FURNACE PRESSURE Another convenient boiler classification is based on the air pressure used in the furnace.
The pressure at which the boiler operates is known as working pressure of the boiler. It mostly refers to steam drum operating pressure when it comes to water tube boilers and shell operating pressure for fire tube boilers.

14. STEAM PRESSURE OPERATING CONTROL: To maintain the desired steam operating pressure on the boiler by regulating the burner to the steam pressure setting. 15. HI-LIMIT PRESSURE CONTROL: Is in addition to the operating control to shut off the main fuel burner supply when the pressure in the boiler exceeds the desired maximum setting.
The boiler pressure is too high. The condensate pump's job is to put the returning condensate back into the boiler. To do this, the pump has to produce a pressure that's higher than the boiler's operating pressure. As a rule of thumb, if the boiler operates at 50 psi or less, the pump should discharge at the boiler's operating pressure, plus ...

Boiler logs are the best method to assure a boiler is receiving the required attention and provide a continuous record of the boiler's operation, maintenance and testing. Because a boiler's operating conditions change slowly over time, a log is the best way to detect significant changes that may otherwise go unnoticed.
Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler's net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
