2. Pace variations and transients
2.1 Variable load operation
To understand how a boiler, and more generally a thermal power plant, operates at variable speeds, several phenomena need to be taken into account.
SCROLL TO TOP2.1.1 Steam pressure as a function of speed
According to Stodola's law, steam pressure at the inlet to a condensing turbine varies linearly with steam flow. The natural and logical characteristic of a steam cycle would therefore be that steam pressure in the boiler varies with plant load. This is known as "sliding pressure"...
