Note the boiler is not fitted with a superheater. In the standard steam locomotive fire-tube boiler, the firebox is surrounded by water space on five sides. The bottom of the firebox is open to atmospheric pressure, but covered by fire grates (solid fuel) or a firing pan (liquid fuel).
A steam generator is a type of boiler used to produce steam for climate control and potable water heating in railroad passenger cars. The output of a railroad steam generator is low-pressure, saturated steam that is passed through a system of pipes and conduits throughout the length of the train.
The rapid passage of gas was indicated by too high a temperature in the smokebox, and the choking of the smokebox by excessive char carried through from the firebox. [2] The boiler was re-tubed with 180 smaller tubes 1 + 7 ⁄ 8 in (48 mm) diameter, and with superheater elements 1 + 1 ⁄ 4 in (32 mm) diameter. [ 2 ]
The HP boiler worked at approx 850 psi (5.86 MPa), and the low-pressure boiler at 200 to 250 psi (1.38 to 1.72 MPa). The UHP and HP boilers were of a water-tube design, while the LP boiler was a fire-tube boiler typical for steam locomotives. The LP cylinders were driven with a mixture of the HP cylinder exhaust and the LP boiler output.
Etching of damage from a boiler explosion in Newark, New Jersey in 1867. This is a list of steam boiler explosions such as railway locomotive, marine transport (military and civilian), and stationary power:
The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes ...
a train brake lever, which controls the application of brakes throughout the length of the train and a locomotive brake lever, controlling brakes on the locomotive only [3]: 12, 93 steam pressure gauges, which show the pressure of the steam in the boiler [3]: 63
A gas turbine locomotive was patented in 1861 by Marc Antoine Francois Mennons (British patent no. 1633). [4] The drawings in Mennons' patent show a locomotive of 0-4-2 wheel arrangement with a cylindrical casing resembling a boiler. At the front of the casing is the compressor, which Mennons calls a ventilator.
