1.1 The heat input to the boiler is controlled by monitoring the rate at which the saturation temperature rises in the drum (the ramp rate) of each pressure level. This rate is limited by; 1) releasing steam through the startup vent, main steam line, or other vent line, 2) controlling the rate at which heat enters the boiler by limiting the

(EPRI) Effect of Flexible Operation On Boiler Components

The Electric Power Research Institute (EPRI) has sponsored considerable research in this area [2–4]. Although damage as a result of flexible operation occurs throughout a fossil-fired unit, the specific area of interest of this project is boiler components, including the boiler enclosure and high-energy piping leading up to the turbine stop

ACTUATORS

Whether a boiler is large or small, subject to severe load swings or base-loaded, Beck actuators provide the best possible damper and valve control. Some of the biggest benefits are realized on boilers subject to extreme load swings, high turndown, or demanding ramp rates. In these cases, Beck actuators have shown that the instantaneous
