What is Boiler Draught? Types, Classification, Advantages

Boiler draught is defined as the difference between absolute gas pressure at any point in flow passage and the ambient atmospheric pressure. It is measured Thus steam jet can be used to produce draught and it is a simple and cheap method. Exhaust steam from the steam engine or turbine can be used easily in the steam jet draught.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Condensing steam locomotive - Wikipedia

A condensing steam locomotive is a type of locomotive designed to recover exhaust steam, either in order to improve range between taking on boiler water, or to reduce emission of steam inside enclosed spaces. The apparatus takes the exhaust steam that would normally be used to produce a draft for the firebox, and routes it through a heat exchanger, into the boiler water tanks.

Draft (boiler) - Wikipedia

Drafting in steam locomotives. Since the stack of a locomotive is too short to provide natural draft, during normal running forced draft is achieved by directing the exhaust steam from the cylinders through a cone (“blast pipe”) upwards and into a skirt at the bottom of the stack. When the locomotive is stationary or in a restricted space “live” steam from the boiler is directed

What is exhaust steam - Definition of exhaust steam - Word

Usage examples of "exhaust steam". Condenser cars (where the exhaust steam was recondensed into water to feed the boilers) became an early feature, as did petroleum fueling in the northern provinces.. As the new water hit bottom, it too turned into steam and needed a way to escape, joining the growing column of exhaust steam and shooting upward, pulling more water in beneath it.

What type of draught is used in a locomotive boiler? - Quora


The steam comes up the blast pipe after it is exhausted from the cylinders and, blowing up the smokestack, induces a draft through the firebed of the firebox via the fire tubes passing through the water space of the boiler. Here is a schematic dia

Nov 25, 2019· In steam ships, we use the liquid diesel oil for firing the boiler. But in ships (Diesel engine driven) the waste heat of main engine is used and hence it increases the overall efficiency of the engine as we are using the heat of the gas that otherwise gone waste in to atmosphere.

Jan 09, 2017· BOILER DRAUGHT 1. BOILER DRAUGHT 2. DEFINITION Boiler draught may be defined as the small difference between the pressure of outside air and that of gases within a furnace or chimney at the grate level, which causes flow of air/hot flue gases to take place through boiler. The draught is necessary to force air through the fuel bed/ grate to aid in proper combustion of fuel and to …
