Boiler Cycling Considerations - Babcock & Wilcox

Many fossil fuel-fired boilers are now experiencing load cycling or on/off cycling operation. These modes of operation involve cycling a unit on and off line or reducing loads to absolute minimums in response to varying load demand. This can be caused by daily or weekly load shifts experienced on nights and weekends, power generators dispatching units to the grid which utilize a lower cost
