Did steam locomotives have condensers?
Roadside tramways In Britain, locomotives working on roadside steam tramways were required by law to have condensers. A steam tram engine usually had a full-length roof and this was surmounted by a nest of air-cooled copper tubes in which the exhaust steam was condensed. Kitson & Company made many engines of this type.

Who invented the condensing steam engine?
James Watt
Artist’s recreation of James Watt inventing the separate condenser for the steam engine, c. 1765. Meanwhile, Watt in 1766 became a land surveyor; for the next eight years he was continuously busy marking out routes for canals in Scotland, work that prevented his making further progress with the steam engine.
How does a steam locomotive firebox work?
A conventional steam locomotive firebox is illustrated below. This drawing shows a simplified cross-sectional view of a typical steam locomotive firebox. Most of the air required to burn the coal (about 90\%) enters through the ashpan and comes up through the grate.
What is the temperature of the firebox in a steam engine?
The firebox peak temperature is approximately 2,500 °F (1,370 °C) For other uses, see Firebox (disambiguation). In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler. Most are somewhat box-shaped, hence the name.
How is steam produced in a steam locomotive?
The production of steam begins with the fire, which rests on grates at the bottom of the firebox. Hot gases rise from the firebed to the upper portion of the firebox, or combustion chamber. On a coal-burning locomotive, the build-up of ash is controlled by shaking the grates so the ashes fall to the ashpan below.
What is the brick arch firebox on a steam locomotive?
Brick arch Firebox of a GWR 6959 Class steam locomotive, showing the underside of the brick arch, constructed from specially-shaped firebricks. 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.
