  • Heat Exchangers | United States | ALSTROM Energy Group LLC

    A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued …Learn More

  • Steam Boiler: What Is It? How Does It Work? Types Of

    Fire Tube Boilers. In a fire tube steam boiler, the tubes on the boiler are heated, and the water circulates around the tubes. The heat inside the tubes is produced by gases heated by coal or oil, and it is transferred by thermal conduction to the water to create steam. Fire …Learn More

  • What is a Steam Boiler? Working, Types of Heat Transfers

    Jul 19, 2019 · These electromagnetic waves in the combustion area come in contact with the tubes where they absorb the heat. This type of heat transfer is known as Radiation.
