A sensor housing system maintains a sensor&#x2014;which is used in monitoring an extreme temperature environment such as a combustion unit&#x2014;at a desired ambient temperature. The system comprises one or more sensors housed within an internal chamber and cooled by air or an inert gas. Gas within the chamber cools the sensor and then exhausts to a second internal chamber which, in turn, exhausts to atmosphere. Both chambers are housed in a directional ball pivot that provides access to the extreme temperature environment and adjusts the angle of the sensor. An air tube having a sweep is directed toward the external surface of the glass wafer and directs a hot gas stream across the surface of the wafer. A failsafe device retracts the chambers from the extreme temperature environment in case of power failure or if for some reason the sensor becomes too hot.

High temperature adjustable sensor housing system apparatus

A multiple purpose burner process and apparatus in which a burner assembly having a burner member defining a burner throat bore extending therethrough and forming an ignition zone and at least one mixing zone in the burner throat bore, the total combustion air passing through the burner throat bore. A minor portion of fuel gas as ignition fuel produces a continuous ignition flame in the ignition zone, and plural meter channels extending through the burner member communicate with the mixing zone to pass an admixture of a diluent gas with the remainder portion of the fuel, as a primary fuel stream, to the mixing zone for forming with the remaining combustion air a primary fuel/diluent/combustion air mixture, and the primary fuel/diluent/combustion air mixture is ignited by the ignition flame in the mixing zone. Diluents can be internally recirculating flue gas or can be from an external source, and the flame envelope achieved by the burner assembly can be variously shaped for an industrial combustion application as required.
