Steam Engine High Pressure, Sample of Term Papers

In most modern large steam turbines, the high-pressure steam is first expanded through a series of impulse stages-sets of nozzles that immediately lower the high initial pressure so that the turbine casing does not have to withstand the high pressures produced in the boiler.

2015-4-30 · High pressure steam locomotive. A high pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 PSI (1.4 to 1.7 MPa). High pressure locomotives can be considered to start at 350 psi, when special construction techniques become necessary, but some

Difference Between Low- and High-Pressure Boilers …

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.

Evaporation: Thermal Recompression Saves Steam …

Using thermal decompression on evaporators, high-pressure steam passes into a thermocompressor through nozzles, transforming the pressure energy that would be otherwise lost into kinetic energy of such magnitude that substantial quantitates of used low-pressure steam can be withdrawn from the evaporator and compressed for re-use.
