  • HTP - Water and Space Heating

    The heat from the hot gases transfers through the walls of the tubes and heats the water. In a water-tube boiler, the water is in the tubes while the fire is external to the tubes. The hot flue gases pass around and between the tubes, heating the water and then out the boiler vent.Learn More

  • Clean Firetube Boiler Waterside Heat Transfer Surfaces

    The bent tube or Stirling boiler allows for a large surface heat transfer area, as well as promoting natural water circulation. Advantages of water-tube boilers: They have a small water content, and therefore respond rapidly to load change and heat input.Learn More

  • Water-tube or fire-tube condensing boiler, which is the

    used to increase the rate of heat transfer through tubes. One of the main factors that affect the boiler efficiency is the proper design of inner wall of the tube which will increase the rate of heat transfer to the flowing water. In order to prevent the damage to the inner walls of tubes and to increase the rateLearn More

  • 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. The burning of coal produces some flue gases, whose heat is also absorbed by the tubes. The Operation of Steam Boiler is shown in the figure below.Learn More
