Abstract
The rates of flow of air, fuel and flue gas are adjusted in parallel from a boiler demand signal. Derived from any conventional source, such as a load dispatch system, steam pressure of the like, but for purposes of illustration shown as originating in a signal generator (11). It is transmitted over a conductor (12) to a fuel control, such as a valve (13), and over a conductor (14), through various signal modifying components, to a forced draft controller (15), and an inducted draft controller (16). Controllers (15) and (16) adjust the forced draft and induced draft by changing the speed of frans (20), and (10) respectively.
