Abstract

A nozzle tor a pilot light tor a flare stack, the nozzle being formed of a housing defined by an encircling cylindrical wall, with radially extending openings formed circumferentially around the encircling wall, and is made of material resistant against breakdown in a sour gas environment at temperatures at least less than 1200°C, preferably 98% by weight alumina ceramic. A cage holds the nozzle, which includes a base plate having a central aperture and first and second sides, a tube extending into the aperture from the first side of the base plate and fixed to the base plate, and plural retainers extending from the base plate and enclosing the nozzle. To form a pilot for a flare stack, a gas conduit is connected into an interior cavity of the nozzle. The cage is attached to a flame stack. The retainer members pass through the nozzle to protect the retainer members from the corrosive environment in which the pilot operates.
