Author: Steam and Gas Power Systems A slightly more successful adoption was the use of hybrid water-tube / fire-tube systems. As the hottest part of a locomotive boiler is the firebox, it was an effective design to use a water-tube design here and a conventional fire-tube boiler as an economiser (i.e. pre-heater) in the usual position.

In a typical Water tube boiler design as shown in the figure, it consists of two drums the steam drum and the water or mud drum. On this design straight tubes were rolled into mud drum, and the front headers were connected to the steam drum. The rear header was connected to a horizontal box header, which was also attached to the steam drum.

Advantages of Water Tube Boiler1. Larger heating surface can be achieved by using more numbers of water tubes. 2. Due to convectional flow, movement of water is much faster thanWorking Principle of Water Tube BoilerMore and more steam is produced the pressure of the closed system increases which obstructs this convectional flow of water and hence rate productiTypes of Water Tube Boiler1.

The feed water is fed to the cross drum through feed water inlet. 2. Then this water comes down through the down-comer pipe and enters into incl Air Cooler a. Tube core in a firebox and consisting of fired heaters, furnaces, and boilers. b. Tube and shell exchanger located on the outlet side of a compressor. c. Banks of tubes connected by a manifold.

The Yarrow boiler design is characteristic of the three-drum boiler: two banks of straight water-tubes are arranged in a triangular row with a single furnace between them. A single steam drum is mounted at the top between them, with smaller water drums at the base of each bank.

Apr 27, 2018· I think you’re putting the cart before the horse. First of all, you need to determine how many square feet of surface on the interiors of the fire tubes are needed to transfer sufficient heat to generate the needed amount of steam. The associated

Three-drum boiler. Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.
