Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler.
suijitupian92.jpg" />High Pressure Boiler - Industrial boiler and power plant
High Pressure Boiler is mostly water tube boiler in which water is on the tube side while flue gas flows through the tube, hence transferring heat from flue gas to water with cross flow heat transfer. A steam boiler is a high pressure boiler when it operates with the steam pressure above 6MPa. The high pressure boiler is widely used for power generation in thermal power plant.

The pressure of the boiler is displayed on a pressure gauge that is built-in. The pressure gauge should read 1 bar mark when the water is running hot and the central heating is off so the 1 bar is the low-pressure setting. Reasons for Boiler Pressure is Too High: The heated water expands as the boiler starts heating the water.

The boiler pressure gauge read 12 psi. The boiler operating pressure control was set for 15 psi. Steam was spewing from the boiler feed vent like an old locomotive. I adjusted the operating pressure control to the normal steam pressure. Within a short time, the boiler operated the way it was supposed to and the building had heat.

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.

When the heating is on the pressure will increase from say 1.5 Bar to about 1.8 Bar and thats quite normal. If the increase is much more than that it implies the pressure vessel is failed of incorrectly pressurised. Then the boiler protects itself by discharging from the PRV to the vent pipe outside.
suijitupian102.jpg" />Boiler water pressure too high | Terry Love Plumbing
Most boilers have a low-pressure cutout switchit must be above that or the boiler won't fire (risks flashing into steam), and they also have a T&P valve that will open if the pressure or temp gets too high. On a boiler, that pressure could be as low as 30-pounds, or it could be higher, depending on the design and use.
suijitupian180.jpg" />Boiler Feed Water Pressure Regulators
Boiler feed water pressure regulators are designed for use in commercial and residential hydronic heating systems to fill the boiler and piping system with water and maintain continuous pressure. Certain valve types also provide make-up water to the system and prevent backflow when supply pressure falls below system pressure.
