Boiler Cycling Considerations - Babcock amp; 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

Boilers | Energy Control Steam and Hot Water Boiler

A steam accumulator is a pressure vessel (or tank) with internals and controls, that can reduce the fuel consumption, maintenance costs and increase the service life of your boiler by stabilizing the steam draw conditions, but it cannot make up for shortcomings in total boiler capacity. The accumulator acts as a flywheel or capacitor, storing energy for short periods until the process requires it.
