Boilers |authorSTREAM

Definition: Definition A boiler or steam generator is a device used to create steam by applying heat energy to water Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers worked at low to medium pressure (1-300 psi /.069-20.684 bar ; 6.895-2,068.427 kPa ) but, at pressures above this, it is more usual to speak of a steam

Steam Heating Process - Load Calculating

In general steam heating is used to. change a product or fluid temperature; maintain a product or fluid temperature; A benefit with steam is the large amount of heat energy that can be transferred. The energy released when steam condenses to water is in the range 2000 - 2250 kJ/kg (depending on the pressure) - compared to water with 80 - 120 kJ/kg (with temperature difference 20 - 30 o C).
