Abstract
Apparatus provides an air/fuel mixture to a fully premixed burner (4) and comprises a fuel line for providing fuel to the burner (4) a fan for supplying air at a variable flow rate to the fuel to form the mixture, a sensor (30) for sensing aeration of the fuel combustion products and a controller (26) for controlling the air flow rate in dependence upon the aeration sensed in such a way that the air flow rate is sufficient to maintain the aeration at or close to a predetermined value, the controller, in use, maintaining the air flow rate at one of a number of differing predetermined values which are in the form of a geometric series characterized by a constant value of the ratio between successive values.
