System for automatically seeking the minimum power deliverable by gas-fired atmospheric burners

摘要

An atmospheric burner is associated with a flame presence sensor and an electrical-discharge ignition device. It is fed via a flow rate control device. Both the ignition device and the flow rate control device are controlled by a microcontroller. A user interface enables the user to select the desired power by sending to the microcontroller a request for altering the flow rate and hence for altering the minimum power deliverable by the burner.
