What is boiler modulation and boiler cycling? - HeatGeek

1/11/2018 · So, what is boiler modulation, or boiler modulation ratio? 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%.

Water Handbook - Boiler Blowdown Control | SUEZ

Control valve settings must be adjusted regularly to increase or decrease the blowdown according to control test results and to maintain close control of boiler water concentrations at all times. When continuous blowdown is used, manual blowdown is usually limited to approximately one short blow per shift to remove suspended solids which may have settled out near the manual blowdown connection.
