Abstract
A boiler control method and system. A BFI (bed fuel inventory) value associated with a boiler can be estimated by detecting data from the boiler utilizing an inferential sensor. The bed fuel inventory value can then be stabilized at a particular value utilizing a feedback controller electrically connected to the inferential sensor, in order to optimize the bed fuel inventory value for varying operating conditions of the boiler, thereby permitting a thermal power associated with the boiler to be increased or decreased faster by respectively increasing or decreasing a primary air supply rate associated with the boiler.
