Nozzle and pilot for the burning of gas

A nozzle for a pilot light, the nozzle comprising;

• a housing defined by an encircling wall, the housing having first and second opposed ends, at least the second end being open for the flow of gas into the housing, and a plurality of openings formed in the encircling wall and extending radially through the encircling wall, the openings being disposed circumferentially around the housing between the first and second ends;
• the housing being made of material characterized by being resistant against breakdown in a sour gas environment at temperatures below 1200.degree. C.;
• further in combination with:
• a cage in which the nozzle is secured;
• an igniter for providing a spark adjacent one of the openings in the nozzle;
• a flare stack;
• a gas supply for the nozzle, the gas supply including a tube extending into the second end of the nozzle;
• an ignition system for the igniter;
• and
• a frame assembly for supporting the igniter, cage and nozzle on the flare stack.

A pilot and flare stack in combination, comprising:

• a nozzle formed by a housing defined by an encircling wall, the housing having first and second opposed ends, at least the second end being open for the flow of gas into the housing, and a plurality of openings formed in the encircling wall and extending radially through the encircling wall, the openings being disposed circumferentially around the housing between the first and second ends;
• the housing being made of ceramic material characterized by being resistant against breakdown in a sour gas environment at temperatures below 1200.degree. C.;
• the housing forming a cylinder having a bore, and the first end including an opening;
• a cage in which the nozzle is secured;
• an igniter for providing a spark adjacent one of the openings in the nozzle;
• a flare stack;
• a gas supply for the nozzle, the gas supply including a tube extending into the second end of the nozzle;
• an ignition system for the igniter;
• and
• a frame assembly for supporting the igniter, cage and nozzle on the flare stack.

A nozzle in combination with a cage, the nozzle and cage comprising:

• a housing defined by an encircling wall, the housing having first and second opposed ends, at least the second end being open for the flow of gas into the housing, and a plurality of openings formed in the encircling wall and extending radially through the encircling wall, the openings being disposed circumferentially around the housing between the first and second ends;
• the housing being made of material characterized by being resistant against breakdown in a sour gas environment at temperatures below 1200.degree. C.;
• 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 for supplying gas into the second end of the nozzle;
• and
• plural retainer members extending from the base plate and securing the nozzle to the base plate.
