Steam Generator vs. Steam Boiler | 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.

Thermal Efficiency of Steam Turbine

2  · Boiler Pressure. An increase in the boiler pressure is in the result limited by material of the reactor pressure vessel. The case of the increase in the average temperature at which energy is added by heat transfer, requires either a superheating of steam produced or an increase in the pressure in the boiler (steam generator).

4 Things to Know for Increasing Steam Boiler

Raising steam for your facility requires water, and depending on the steam plant's size and design, the volume of feedwater needed can be small or quite large. Some applications allow for steam condensate to be recycled back to the boiler which is reused as part of the feedwater, with the rest coming in as fresh water, called makeup.
