Abstract
An intelligent burner control apparatus is provided for controlling the rate of air and fuel flow in a burner system from air and fuel supplies to a burner. The apparatus includes a peer-to-peer communication network including a plurality of network control modules that communicate with each other over the communication network. The apparatus further includes a brain module including one of said network control modules coupled to the communication network, air and fuel flow controllers including one of said network control modules coupled to the communication network, and air and fuel flow regulators including one of said network control modules coupled to the communication network. The brain module is configured to send air and fuel setpoint signals over the communication network to the air and fuel flow controllers. The air and fuel flow controllers measure the flow of air and fuel to the burner and send air and fuel flow control signals over the communication network to the air and fuel flow regulators which then regulate the flow rate of air and fuel to the burner.
