Firebox of a GWR 6959 Class steam locomotive, showing the underside of the brick arch, constructed from specially-shaped firebricks. Empty firebox of a Baureihe 52, showing the brick arch. There is a large brick arch (made from fire brick) attached to the front wall (boiler throat plate) of the firebox immediately beneath the firetubes. This ...
The Gothic arch firebox was also notably used by a number of Gooch's Great Western Railway broad-gauge locomotives, [4] [7] including the Firefly, Leo and Hercules classes of 1840-1842. The last class to use them was the Premier class of 1846–7, which were also the first locomotives to be constructed at the new Swindon Works. [8]
A locomotive boiler with a wide firebox may have arch tubes or thermic syphons. As firebox technology developed, it was found that placing a baffle of firebricks (heat-resistant bricks) inside the firebox to direct the flow of hot flue gasses up into the top of the firebox before it flowed into the fire tubes increased efficiency by equalizing ...
The hatched circles show the outline of the barrel to which the firebox was attached. A Round-topped firebox cross section shown for comparison. Note the angling of the stays. Pacific-type flat-topped inner firebox. The Belpaire firebox is a type of firebox used on steam locomotives. It was invented by Alfred Belpaire of Belgium in 1864. Today ...
4-6-0 camelback locomotive, complete with Wootten firebox. The Wootten firebox is a type of firebox used on steam locomotives. The firebox was very wide to allow combustion of anthracite waste, known as "culm". [1] Its size necessitated unusual placement of the crew, examples being camelback locomotives. The Wootten firebox made for a free ...
The diagram, which is not to scale, is a composite of various designs in the late steam era. Some components shown are not the same as, or are not present, on some locomotives – for example, on smaller or articulated types. Conversely, some locomotives have components not listed here.
Clean the firebox of both wood-burning and gas fireplaces. A wood-burning fireplace will need a good, deep clean that removes any leftover ash or soot from the previous year. A gas fireplace needs ...
The square-topped Belpaire firebox allows steam to be conveniently collected at its top corners and therefore locomotives with Belpaire fireboxes often dispensed with a dome, for example express engines such as the GWR Castle Class (the large brass boiler fitting on a Castle is the distinctive GWR safety valve cover, not a dome).
