high pressure boiler Agents in steam power plants


Numerical method for determining the allowable

The new generation of steam power plants operates at pressures higher than the critical pressure and at very high temperatures. They are called supercritical power plants and their thermal efficiency is improved by increasing their operating pressure and temperature.

Power-Augmented Steam Power Plant in a

A double-flash steam power plant is considered for theoretical demonstration of power augmentation with a cement factory's waste heat recovery compared to a regular steam power plant. The hot water from the final flash chamber is used for feedwater heating and the saturated steam from the two flash chambers is supplied to the turbine.
