The boiler is better able to respond to large loads as the 'low fire' position will ensure that there is more stored energy in the boiler. If the large load is applied when the burner is on 'low fire', it can immediately respond by increasing the firing rate to 'high fire', for example the purge cycle can be omitted.

Cycle Efficiency - an overview | ScienceDirect Topics
The steam in a reheat Rankine cycle leaves the boiler and enters the turbine at 60 bar and 390 °C. It leaves the condenser as a saturated liquid. The steam is expanded in the high-pressure turbine to a pressure of 13 bar and reheated in the boiler at 390 °C. It then enters the low-pressure turbine, where it expends to a pressure of 0.16 bar.

STEAM AIR PREHEATER FOR A STEAM BOILER
After passing through steam air preheater 60, the exhaust steam of boiler feed pump turbine 50 is conducted through drain 61 to condenser hotwell 35 where it re-enters the main steam cycle. After passing through steam air preheater 60, the intake air is at about 90° - 150° F.
