Abstract
An intelligent burner control apparatus is configured to control the flow rate of a fluid flowing from a fluid supply to a burner. The apparatus includes a flow controller, a flow regulator, and a flow monitor. The flow controller includes a sensor configured to measure the flow rate of the fluid. The flow controller is configured to determine a flow control signal based on a measured fluid flow rate. The flow regulator is configured to receive the flow control signal and includes a valve movable to control the flow rate of the fluid in response to the flow control signal. The flow monitor is configured to monitor a change in the position of the valve with respect to the measured fluid flow rate and to produce an alarm signal when the change in the position of the valve with respect to the measured fluid flow rate is outside of a predetermined threshold.
