High Pressure Boilers: Features and Advantages ~ ME Mechanical

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.

Water-tube boiler - Wikipedia

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
