Abstract

A device for combustion control, especially for gas-fed boiler burners, comprises at least an optical sensor (10) constituted of one or more photodetectors, oriented in the direction of one or more defined zones of flame (12) of a boiler (14), whose electric signals supplied at the outlet are acquired by a card for a data elaboration system (16) based on neural networks and fuzzy logic, said system interacting with the electronic card (18) for the control of said boiler (14).
