    Water compartment Tank for water to be used by the boiler to produce steam. [3]: 79 Coal bunker Compartment for storage of fuel before being directed to the firebox. When the fuel is coal (and in the distant past, coke or wood), the fireman shovels it manually through the firebox door or, in larger locomotives, by operating a mechanical stoker.

  3. GWR 0-6-0PT - Wikipedia

    en.wikipedia.org/wiki/GWR_0-6-0PT

    The GWR 0-6-0PT (pannier tank), is a type of steam locomotive built by the British Great Western Railway with the water tanks carried on both sides of the boiler, in the manner of panniers. They were used for local, suburban and branch line passenger and goods traffic, for shunting duties, and as banker engines on inclines.

  4. Hydropneumatic device - Wikipedia

    en.wikipedia.org/wiki/Hydropneumatic_device

    See also expansion tank. When shock waves of an incompressible fluid within a piping system exist, especially at a high velocity, there is a high chance for water hammer. To help prevent a swing check from slamming and causing water hammer, a spring-assisted non-slam check valve is installed.

  5. GWR 2721 Class - Wikipedia

    en.wikipedia.org/wiki/GWR_2721_Class

    The biggest change was the fitting of a Belpaire firebox necessitating a pair of pannier tanks, as the square-topped firebox is not compatible with a curved saddle tank. Highlighting the gradual nature of the changes are the subtle differences between the 1854 and 2721 classes, confined to a small increase in wheel size by 1 + 1 ⁄ 2 inches ...

  6. Damper (flow) - Wikipedia

    en.wikipedia.org/wiki/Damper_(flow)

    This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to ...

  7. Tuned mass damper - Wikipedia

    en.wikipedia.org/wiki/Tuned_mass_damper

    The graph shows the effect of a tuned mass damper on a simple spring–mass–damper system, excited by vibrations with an amplitude of one unit of force applied to the main mass, m 1. An important measure of performance is the ratio of the force on the motor mounts to the force vibrating the motor, ⁠ F 0 / F 1 ⁠ .

  8. Piping and plumbing fitting - Wikipedia

    en.wikipedia.org/wiki/Piping_and_plumbing_fitting

    a fitting that connects pipes of different diameters, genders, or threads (see § Coupling below) [10] adapter spools (also called crossover spools), used on oilfields and pressure control, have different diameters, pressure ratings or designs at each end [11] adapters to convert NPT to BSP pipe threads are available [12]

  9. Steam drum - Wikipedia

    en.wikipedia.org/wiki/Steam_drum

    Its accessories include a safety valve, water-level indicator and level controller. Feed-water of boiler is also fed to the steam drum through a feed pipe extending inside the drum, along the length of the steam drum. A steam drum is used without or in the company of a mud-drum/feed water drum which is located at a lower level.
