Steam Boiler - Definition, Working Principle, Types, and

A steam boiler is a power generation device, used for generating steam by applying the heat energy to water. The pressure range of earlier boilers ranges from low pressure to medium pressure (7 kPa to 2000 kPa/ 1psi to 290 psi). The present boilers are more useful because it works with high pressure than old ones.

High Pressure Boiler: What is it? Types & Characteristics

Characteristics of a High Pressure Boiler Power of Steam: Water expands 1600 times to form steam, which can carry large amounts of heat. This makes water an economical and ideal raw material for generating heat and power. High pressure boilers heat water to create steam at over 15 psi and have water pressure over 160 psig. Combustion Efficiency
