THE CLAYTON GUIDE TO STEAM GENERATI

2011-10-26·steam flow is synchronised with the speed of the pump and the heat source - so it can ramp up and down in seconds with unrivalled fuel efficiency. And when it is not needed at the end of the working day it can be switched off with the lights to conserve energy. The basic operating principle produces one advantage that leads to another and another.

Boiler Design for modern coal fired Power Plants

Designing the boiler for low minimum once-through load affects the evaporator design and makes more sense if such low loads can still be achieved without the need for secondary fuel firing. The limitation of the steam temperatures up to 550 / 570 °C allows a high number of hot starts and a daily start-up and shut-down of the unit.
