  • How does a Fire Tube Boiler work?| What are types of Fire

    A superheater may be found in steam boilers. A superheater is a device found in steam boilers that is used to convert wet, saturated steam into dry steam. Superheaters are a very beneficial part of the steam cycle, because dry steam contains more thermal energy and increases the overall efficiency of the cycle. Not only that, dry steam also is less likely to condense within the cylinders of a reciprocating engine or the casing of a steam turbine.Learn More

  • What are the four passes of a fire tube boiler? - Quora

    Answer: A fire tube boiler only has 4 passes if it is constructed that way.
