A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

Water level low: Maintain water level in the boiler at half-full.The boiler's automatic filling system, controlled by the pressure-reducing valve, should maintain the proper water level at 12 to 15 psi of pressure.
Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to large furnaces
The pressure relief valve, also as known as a blow-off valve, is a vital component of a boiler. Without a properly working valve, dangerous levels of temperature and/or pressure may build up in a home's heating system. Extreme pressure within the system could cause the boiler or water lines to rupture.
Low pressure boiler operates at a pressure of 15 PSI or lower (RSA 157-A:2,VI). High pressure boiler operates at a pressure greater than 15 PSI Inspectors holding a National Board Commission and employed by a Jurisdiction or an Insurance Company writing this type of insurance in New Hampshire (RSA 157-A:7).

The flow rates are about twice as high as those of a comparable boiler feed pump in a fossil-fuelled power station. Casing For boiler feed pumps two factors have to be considered regarding the wall thickness of the casing: the pressure loads and the different temperature conditions it needs to withstand.
A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads. TYPES OF BOILERS. There are two types:
Inspections are required at 1, 2 and 3 year intervals depending on the type of equipment. High pressure boilers require internal inspections annually. Low pressure boilers typically used for heating and supplying potable hot water are inspected every 2 years. Pressure vessels are required to be inspected every 3 years. (see 430 ILCS 75/10)
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.
These high pressure boilers have pressures above 140 bar and the temperature may be up to 540 - 610°C. High pressure boilers use both natural and forced circulations. Forced circulation is achieved with the help of centrifugal pumps. By using this forced circulation, because of high velocity of water scale formation in the tubes and boiler
