Abstract Deployment of renewables introduces new regimes of large scale boiler operation. The units are required to operate at flexible rather than baseload mode. One of the requirements is to reduce the minimum load of the existing boilers which adds thermal stress to pressure parts. Significant operational issue is the local overheating of the heat exchangers material due to …

With oil-burning and gas-burning boiler efficiencies over 90%, power plants are examining all associated processes and controls for efficiency improvements. Between 1 and 3% of the gross work produced by a boiler is used to pump feedwater. One method of improving overall efficiency is by controlling feedwater pump speed to save on pump power.
