Water substance at 70 bar and 65 oC enters a boiler tube of constant inside diameter of 25 mm. The water leaves the boiler tube at 50 bar and 700 oK at velocity of 100 m/s. Calculate Get Price
Fire tube boilers are most commonly used in steam heating systems for average buildings. Cast iron sectional boilers are also used, although not as often. The steam from the boiler can be used in a heat exchanger (converter) to heat the water required for a hot water heating system. Hot Water Boilers (Generators)Get Price

The steam turbine operates on basic principles of thermodynamics using the part 3-4 of the Rankine cycle shown in the adjoining diagram. Superheated steam (or dry saturated steam, depending on application) leaves the boiler at high temperature and high pressure. At entry to the turbine, the steam gains kinetic energy by passing through a nozzle Get Price
A steam locomotive is a rail vehicle that provides the force to move itself and other vehicles by means of the expansion of steam.: 80 It is fuelled by burning combustible material (usually coal, oil or – now rare – wood) to heat water in the locomotive's boiler to the point when it becomes gaseous and its volume increases 1,700 times. . Functionally, it is a steam engiGet Price

Fire tube boilers have low initial cost, and are more compacts. But they are more likely to explosion, water volume is large and due to poor circulation they cannot meet quickly the change in steam demand. For the same output the outer shell of fire tube boilers is much larger than the shell of water-tube boiler.Get Price
