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 inner firebox was D-shaped in plan, with a flat tubeplate. Fireboxes of this time did not yet have a brick arch and so the Bury firebox was relatively short in length but tall, to give an adequate length of combustion path. The outer firebox was a vertical cylinder, formed into a tall hemispherical dome above it. [3]
Fireplace in the Colonel McNeal House showing coal grated firebox and mirror above. A firebox or firepit is the part of the fireplace where fuel is combusted, in distinction from the hearth, chimney, mantel, overdoor and flue elements of the total fireplace system. The firebox normally sits on a masonry base at the floor level of the room.
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 ...

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. When the fuel is oil, it is sprayed into the firebox from a sealed tank. [2] [3]: 79 Grate
Prior to the developments leading to the use of pulverized coal, most boilers utilized grate firing where the fuel was mechanically distributed onto a moving grate at the bottom of the firebox in a partially crushed gravel-like form. Air for combustion was blown upward through the grate carrying the lighter ash and smaller particles of unburned ...
