Air is drawn up through the firebox grate by the vacuum and mixes with the fuel, continuing the combustion process. Locomotive boilers use a special type of safety valve known as the locomotive type safety valve. This type has extremely rugged construction and high accuracy, giving it the ability to discharge repeatedly without losing its Learn More
A large locomotive boiler would have well more than 200 of these tubes, plus possibly 40 or so larger tubes at the top for the superheater units; the superheater units extended into these larger tubes from the superheater header ahead of the front flue sheet. The stresses from heating & cooling, and yes the pulsating exhaust vacuum could Learn More
Sep 09, 2020 · Locomotive boiler is a boiler type that is used to heat up the water and create steam from this water. This boiler sits horizontally, just like Lancashire boiler and Cornish boiler. Many people think that Locomotive boiler is a water tube boiler, but in fact, it's a fire-tube boiler. Locomotive boiler's main function is to generate a high Learn More
Model locomotive boilers are broadly similar in layout with some notable exceptions: If the inlet valve has stuck, indicated by the pump handle springing back under the effect of vacuum, release it by draining the cold water from the tank and adding some hot water from a kettle.Learn More
Not into the boiler — up the smokestack. When the locomotive is running under power, a draught on the fire is created by the exhaust steam directed up the smokestack. Without a significant draught, the fire will quickly die down and steam pressureLearn More
LOCOMOTIVE ENGINE Running and Management - INJECTORS. CHAPTER XI. INJECTORS. ALTHOUGH the injector is not theoretically so efficient as a good pump, practically it has proved itself the best means of feeding water to locomotive boilers that has ever been tried. When a well-made injector is used regularly, it is more reliable than any form of Learn More
Locomotive boiler is a horizontal drum axis, multi-tubular, natural circulation, artificial draft, forced circulation, mobile, medium pressure, solid fuel fired fire tube boiler with an internally fired furnace. It is used in railway locomotive engines and in marine. It is a mobile boiler and has a …Learn More
Locomotive boiler Definition: A locomotive boiler is a multi-tubular boiler and it has a horizontal drum axis. The circulation in the locomotive boiler is natural, also it is a medium pressure boiler, the draft is artificial, forced circulation, mobile, solid fuel fired fire tube boiler.Learn More
Pulling A Vacuum. When boilers are designed to operate at very high pressures, they are not designed to operate under even the slightest vacuum. A potential vacuum is created when a boiler is shut down. As the unit cools, the steam condenses and water level drops, which allows the pressure to drop.Learn More
J50/4 14 built 1938–39, 4 ft 5 in boiler, vacuum brake, left-hand drive, long bunker with hopper; All were built at Doncaster, except the last fourteen which were built at Gorton. Further orders were placed in 1939 and 1941 totalling 25 more locomotives, but these were cancelled in 1942 after a number of components had been manufactured.Learn More
A safety valve is a valve mechanism for the automatic release of steam from the boiler of a steam locomotive, which helps prevent from a steam locomotive from exploding. Safety valves were first used on steam locomotives during the industrial revolution in the late-1800's. Early boilers without them were prone to accidental explosion. They are equipped on just about every steam locomotive Learn More
As the name denotes "Locomotive Boiler" that means these types of boiler moves with a certain velocity.Generally, it moves with a velocity of 60 to 70 km/hour. The construction of this is the same as any fire tube boiler with a little difference, and that differences I will mention below in this article.. Also at the end of the article, I will give you the PDF downloadable link of this Learn More
In line pipe fitting and threaded body boiler fittings (90 degree). Chime Whistles . 3 note chime whistles in polished brass, 2 sizes available. Locomotive type drain cocks in sets of 4 (2 left hand 2 right hand) in various sizes and threads, Stuart models types also available. Used in vacuum braking systems to limit train pipe vacuum.Learn More
locomotive boiler takes advantage of the release of the energy contained within the latent heat of evaporation to vacuum ejector, a steam-jet ejector, or an aspirator. Key design parameters The compression ratio of the injector,, is defined as ratio of the injectors's outlet pressure to the inletLearn More
The boiler thus became, in effect, a kind of tender, and the vehicle which in normal practice is known as the tender became the engine. This gave the designer more room for his turbines. At the same time the great weight of the condenser and tanks furnished the essential factor of adhesion which is provided, in an ordinary locomotive, by the Learn More

Steam locomotive nomenclature is a listing of the components found on a Steam Locomotive. Fig. 1: Steam Locomotive Fig. 2: Steam Locomotive and Tender The following components appear on the illustrations shown above. Boiler — A water container that is brought to a boil by hot gases passed through long tubes, thereby producing steam. From time to time the tubes need to be cleaned as they Learn More

1 1/2″ scale miniature of a 7Ft diameter boiler. Cutaway boiler demonstrates the workings of the Cochran cross-tube vertical boiler, including coal firing firebox, fire-tubes and smokebox, and all the typical Cochran features of full size boilers including external firebox and mud hole doors.Learn More
There are two technologies that separate modern steam locomotives from traditional locomotives: the implementation of the Gas Producer Combustion System (GPCS) in place of conventional steam locomotive combustion (which works in tandem with a high efficiency exhaust) and the use of a modern and much more effective internal boiler water treatment regime than was available during the US …Learn More
