Abstract: A method and system are disclosed for providing fuel and air to a furnace. The furnace includes a plurality of burner assemblies, each with its own air valve for controlling the flow of combustion air therethrough. A sensing instrument for each burner assembly senses a condition reflecting the individual performance of that particular, separate burner assembly. A controller is coupled with the sensing instruments and with the air valves of the burner assemblies for controlling each individual air valve in response to the performance reflecting condition sensed by each sensing instrument. This results in individual control of the performance of each burner assembly of the set of burner assemblies feeding fuel and air to the furnace.
