Questions and Answers

What is the function of a steam generator?

A steam generator generates steam at the desired rate at the desired pressure and temperature by running fuel in its furnace.

List the components of a steam generator.

Components of a steam generator include furnace, superheater, reheater, boiler or evaporator, economizer, air preheater, pulverizers, burners, fans, stokers, dust collectors, precipitators, ash handling equipment, and chimney/stack.

What is the boiler or evaporator in a steam generator responsible for?

The boiler or evaporator is responsible for the phase change or boiling from liquid (water) to vapor (steam) at constant pressure and temperature.

    • Superheater
    • Economizer
    • Feedwater system
    • Steam drum
    • Water walls
    • Combustion chamber
    • Air preheater
    • Furnace
    • Blowdown system
    • Control system
    • Ash handling system
    • Fan system
    • Fuel supply system
    • De-aerator
    • Deaerator heater
    • Reheaters
    • Circulating pumps

Boiler (Evaporator)

  • Function: Heats the water to its boiling point and converts it to steam.

  • Traditional Term: "Boiler" is often used interchangeably with "steam generator," particularly in older texts.

  • Definition: A vessel where water is heated under pressure to produce steam.

  • Purpose: To transfer heat from the combustion of fuel to water, ultimately creating steam.
