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.
Boiler Types - There are many different types of boilers in the boiler room today in a variety of heating applications. There are two main categories of boilers among the different boilers and those two categories are steam boilers and hot water boilers.Either of those categories can be fueled by oil, gas, or electric (although electric is uncommon for steam boilers).

Steam Boiler Types. The steam boilers are classified into several types based on its requirement. Water Tube Boiler. The water tube boiler is one type of boiler, and the main function of this boiler is the water in
If the steam escaping rate is high compare to water feeding rate, the pressure of the boiler decreases. And if the water feeding rate is high compare to steam escaping rate the pressure of the boiler increases. Thus the boiler pressure is controlled by the fuel supply and water supply of the container. This is the basic working of a boiler.
2019-11-28 · A boiler is called a high pressure boiler when it operates with a steam pressure above 6.0 MPa. The high-pressure boilers are widely used for power generation in thermal power plants.
