pressure of steam in boiler
Steam BoilerDefinition 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 Get a Quote
