Steam generator tube expansion process

Steam Generator OR Steam Boiler? - Process Heating

expansion process during the manufa cturing of the steam generators. Consider a long pressurized tube which is fixed into a drilled tubesheet by the means of expansion (Fig. 1.). The tube contains an axial through wall crack with length 2 a. The failure mode of concern is the unstable (ductile) propag ation of the crack leading to tube rupture.

Steam Generators vs. Steam Boilers - Powerhouse

As water passes through the coil, the heat is transferred from the hot gases which causes the water to convert to steam. The generator design does not utilize a steam drum where the steam of a boiler has a disengagement area from the water in so the use of a steam/water separator to achieve 99.5% steam quality is required.

What is Boiler and Condenser Pressure - Rankine Cycle

May 22, 2019 · Reheater – removes the moisture and increases steam temperature after a partial expansion. The process of superheating is the only way to increase the peak temperature of the Rankine cycle 626°F) is pumped into the steam generator through primary inlet. This requires maintaining of very high pressures to keep the water in the liquid state.

generation, steam turbine generators normally generate elec tricity as a byproduct of heat (steam) generation. A steam turbine is captive to a separate heat source and does not directly convert fuel to electric energy. The energy is transferred from the boiler to the turbine through high pressure steam that powers the turbine and generator.
