  • Firetube vs. Watertube Comparison - Johnston Boiler

    The watertube boiler design has a heat transfer ratio that typically falls between 0.07 square feet and 0.10 square feet of heat transfer surface per pound of steam per hour produced. The furnace volume available for combustion varies widely with the three styles of watertube boilers.Learn More

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

    These design changes have resulted in a marked improvement in heat transfer efficiency of the fire-tube boilers. Another outcome from this is that the overall footprint (boiler size) of the fire-tube boilers will be smaller in comparison to the water-tube boilers only in the lower capacities up to about 4,000,000 BTU/hr.Learn More

    Jan 02, 2018 · Abstract. In this work, we are interested to simulate the transient thermal-hydraulic behaviour of 3-pass fire-tube boiler during a cold start-up. A transient thermal model has been developed based upon energy balance equations of the main components of the boiler and the relevant correlations describing heat transfer phenomena taking place. The variation of the main thermal parameters describing the boiler dynamic behaviour, namely: temperatures of combustion gas, tube …Learn More

  • Top PDF Fire-tube boiler - 1Library

    A fire tube boiler is a type of boiler in which hot gases from a fire passes 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.Learn More

  • BOILER TYPES FOR STEAM APPLICATIONS

    Heat transfer from the tube to water is easy, but hard for flue gas to the tube. For a Firetube boiler, this means notches in the inside of the tube. In a Watertube, this could mean adding fins to the outside of tubes. Again, all these methods will improve the heat transfer but at the cost of larger fans and motors.Learn More

  • Types Of Boiler Water Tube And Fire Tube

    Mar 29, 2017 · Boiler Types According to tubing methods Ther e are two main types of boiler Fire tube boilers and water tube boilers. Fire tube boilers are those boilers in which fire or flue gases are inside of the tubes and water is on the shell side. Fire Tube Boilers are low capacity low-pressure boilers usually used for heating, processor Learn More

  • Water Tube Boiler: Definition, Types, Advantages

    The movement of water is much faster than the fire tube boiler because of conventional flow, hence the rate of heat transfer is high which results in higher efficiency. Water boiler: Overall efficiency is up to 90%. In the water boiler: The maximum working pressure is 250 bar or you can say 140 kg/cm2.Learn More

  • What is a Waste Heat Boiler? (with picture)

    A waste heat boiler of the water-tube design is able to cope with much higher pressures of steam than a fire-tube boiler, but it is more difficult to construct and install. Inside this type of boiler, there are narrower tubes than inside a fire-tube boiler, and the tubes contain water instead of hot gases.Learn More
