Boiler types According to steam Pressure. Low pressure Boilers, Medium Pressure Boilers and High Pressure boilers. According to ASME there every boiler have pressure above 15 PSI is called high pressure boiler. but generally Low pressure boilers having pressure below 300 psi (Bulk Boiling).

Boiler (power generation) Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator .

Question: Boiler pressure In tanker vessels we use boilers for cargo heating. Lets say that steam pressure to deck line adjusted to 5 bar. What will be most economical? Boiler pressure adjusted to 7 bar or to 16 bar ? Answer: The higher pressure would be advantageous if the boiler is oil-fired, but the difference is hardly measurable.

Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler. It is a fuel-fired hot water heater. Because of its similarities in many ways to a steam boiler, the term ''hot water boiler'' is used.

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.:Jan Berry · Bob Griffin · Anthony L Wright: Oak Ridge National Laboratory:Distributed computing · Fuel efficiency · Renewable energy · Electricity generation · EffiThe National Board of Boiler and Pressure Vessel InspectorsSteam boilers require a device which senses steam pressure and cycles the burner or other source of heat in order to maintain a consistent, predetermined operating pressure. A second device is used to prevent the boiler from exceeding the maximum allowable working pressure (MAWP) indicated on the boiler nameplate.

Johnson boiler: one of the first "modern" classes of high-pressure marine oil-fired water-tube boilers. They have a single steam drum above a single water drum. Their small-diameter water-tubes curve outwards on each side to form a cylindrical furnace. As there is no grate or ashpan beneath, firing must be by oil.

Low pressure steam boilers still require a pressure/temperature safety relief valve. A pressure relief valve is a spring-loaded device that will open to spill excess pressure (and temperature) in the form of water, steam, or a mix of the two, at a pre-determined pressure in order to protect the heating appliance from damage, or worse, a dangerous BLEVE explosion.
