A furnace camera, including one or more image sensors for detecting one or more optical characteristics of a product resulting from a combustion process; and a burn-resistant body having an inner channel and an outer channel, said inner channel extending through said body between an inlet opening and an outlet opening, said inner channel having one or more optical elements positioned therein for adapting light received through said outlet opening for detection by said image sensors; wherein, said outer channel is adapted for directing a flow of fluid around said inner channel to minimise exposure of said inner channel to excessive heat when said system is in use, and said inner channel is adapted for directing a flow of gas to minimise exposure of said one or more optical elements to excessive heat when said system is in use. |
