Boiler (power generation) - Wikipedia

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 and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.Steam generator · Boiler types· Structural resistance· CombustionBoiler Economiser : Definition, Function & Types of Boiler Economiser Definition. Boiler Economiser ( Sometimes Called Economizer ) is the Energy improving device that helps to reduce the cost of operation by saving the fuel.. The economizer in Boiler tends to make the system more energy efficient.. In boilers, economizers are generally Heat Exchangers which are designed to exchange heat with the fluid, generally water.
