Steam Boiler - Definition, Working Principle, Types, and Applications

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.
