Boiler Concentration Cycles

Boiler Cycling Considerations - babcock.com

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

The Value of Good Boiler Blowdown Control -

The phrase cycles of concentration is the basis for one of the most important concepts in boiler water treatment. The feedwater cycles reflect the extent impurities in the feedwater concentrate in the boiler water. The higher the feedwater cycles, the more the feedwater impurities have been concentrated in the boiler water and the lower

2012-1-1· Cycles of concentration: Since the condensate is low in dissolved solids, the more returned, the lower the concentration of dissolved solids. This will help increase the boiler cycles of concentration thereby reducing the blow-down, which means a lower amount of heat lost through the blow-down.

Boiler Water Treatment & Chemical Treatment |

The relationship between the level of dissolved solids in the boiler and the dissolved solids in the feedwater is termed cycles of concentration. Water is drained, or blown down, from the boiler periodically to maintain a consistent number of cycles of concentration. This process is essential to the prevention of scale and corrosion in your boiler.
