The cycles of concentration can 'be determined by comparing the concentration of dissolved solids in the boiler water to the concentration in the feedwater. Cycles can than be calculated (note that the blowdown concentration is the same as the boiler concentration) Bs or C= B mmho Fs Fmmho Where: C= Cycles of concentration, no unit Bs = Blowdown TDS, ppm.

Boiler Cycling Considerations - Babcock & Wilcox

Boiler Cycling Considerations. 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

Calculating Boiler Chemical Requirements – Water …

26/6/2017 · Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm. To develop this alkalinity, we need 25 ppm soda ash (as CaCO 3 ) in the feedwater (250 ppm boiler alkalinity divided by 10 concentrations), over and above the amount required to neutralize non-carbonate hardness in the feedwater.

What is boiler modulation and boiler cycling? - HeatGeek

1/11/2018 · Boiler modulation is the ability of a boiler to 'turn down' its output. That is to say if you have a 20kw boiler, but you only require 10kw of heat for the next hour, rather than outputting 20kw for 5 minutes then resting 5 minutes repeatedly, (how the older non-modulating boilers used to work) the boiler will simply turn down its flame by 50%.
