How Do Burner Combustion Control Systems Work? - CrossCo

In its most simple form the air flow SP is the greater of the boiler master and the actual fuel flow PV (%) and the fuel flow SP is the lesser of the boiler master and the actual air flow PV (% after it is run through the FAR PWC and O 2-trimmed). This forces air to lead on firing rate increases and fuel to lead on decreases and ensures that if the system ever runs out of air it will never add too much fuel.

Power Plant Efficiency Simulator Laboratory

The steam expands in the turbine and does work which enables the turbine to drive the electric generator. The exhaust steam leaves the turbine and enters the condenser where heat is transferred from the steam to cooling water. The pressure of the condensate leaving the condenser is increased in the pump thereby enabling the condensate to flow into the boiler.

Pumps-to-System Control of Power Plant Boiler Feed Pumps

In general the power plant boiler feed pump is sized to provide full feed water flow plus some amount of spray water all at maximum continuous rating (MCR). In theory this point should be as close as possible to 90 percent BEP (leaving a little extra to recover from low drum levels at full load and during transients).
