Boiler Cycling ConsiderationsBabcock
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

Steam Generator vs. Steam Boiler Powerhouse
In a firetube design a steam boiler is a pressure vessel comprised of a large shell in which the hot gases of combustion pass through one or more boiler tubes connected to the front and rear boiler sheet. The most common firetube type is the scotch marine firetube boiler which utilizes a large furnace tube and many smaller boiler tubes.

· The flue-gas temperature of a typical boiler could be anywhere in the range of 300 to 500 degrees Fahrenheit range. As a result the extra oxygen could have entered the boiler at 70 degrees F and exit at 400 F. The extra oxygen reached this temperature by receiving fuel energyin other words fuel was purchased to heat the extra oxygen.

· As stated when you raise boiler temp you raise stack temp. As stack temp increases the O2 decreases and the flame cools off due to more air over the flame. Stack increase higher O2 cooler flame equals less efficient. Remember efficiencies are tested at 120 return temp and 140f supply temp under AFUE procedures.
