The major disadvantage to this method of control is that the boiler is subjected to large and often frequent thermal shocks every time the boiler fires. Its use should therefore be limited to small boilers up to 500 kg/h. Advantages of an on/off control system: Simple. Least expensive. Disadvantages of an on/off control system

Nov 07, 2019 · The importance of draft control. The purpose of the boiler stack and breeching (for multiple boilers) is to provide the draft required by the boiler and burner manufacturer to evacuate flue gases to the point of a safe discharge. Typically, this draft requirement is around 0.05-0.5 inches water column of negative or positive draft.

Most NOx control technologies for industrial boilers, with inputs less than 100 MMBtu/hr, reduce thermal NOx and have little affect on fuel NOx. Fuel NOx is most economically reduced in commercial and industrial boilers by switching to cleaner fuels (fuels containing less fuel-bound nitrogen), if available.
