Flare pilot and flare pilot with ignitor assembly

A pilot assembly (100) for use with a flare stack (10) having a first flare stack (10a) and a second flare stack (10b), each of the first flare stack (10a) and a second flare stack (10b) comprising a flare (12) having a discharge end (18), the pilot assembly (100) comprising:

• a pilot nozzle assembly (102);
• a pilot inlet pipe (110) having a pilot fuel inlet (120);
• and
• a pilot ignition system (30);
• wherein the pilot nozzle assembly (102) comprises:
• a connecting member (103);
• a single pilot nozzle inlet (104);
• and
• a plurality of nozzle outlets (106a, 106b);
• at least one flame front nozzle (36);
• wherein the pilot nozzle assembly (102) is in fluid communication with said pilot inlet pipe (110);
• wherein the pilot nozzle assembly (102) further comprises a first pilot nozzle (102a) and a second pilot nozzle (102b);
• wherein said pilot assembly (100) further comprises a flame front deflector (130) between the first pilot nozzle (102a) and the second pilot nozzle (102b);
• wherein the connecting member (103) comprises a plurality of conduits (103a, 103b) fluidly connecting the pilot nozzle inlet (104) to the first pilot nozzle (102a) and the second pilot nozzle (102b);
• and
• wherein the flame front deflector (130) is positioned within the pilot assembly (100) to deflect a flame front FF from said at least one flame front nozzle (36) towards said pilot nozzles (102a, 102b).

A pilot nozzle assembly (102) for use with a pilot assembly (100) of a flare stack (10) having a flare (12) with a discharge end (18), the pilot nozzle assembly (102) comprising:

• a connecting member (103);
• a single pilot nozzle inlet (104);
• a plurality of nozzle outlets (106a, 106b);
• at least two pilot nozzles (102a, 102b) each terminating in one of said plurality of nozzle outlets (106a, 106b);
• and
• at least one flame front nozzle (36);
• wherein the connecting member (103) comprises a plurality of conduits (103a, 103b) fluidly connecting the pilot nozzle inlet (104) and the pilot nozzles (102a, 102b);
• wherein said nozzle assembly (102) further comprises a flame front deflector (130) between the first pilot nozzle (102a) and the second pilot nozzle (102b);
• wherein said plurality of nozzle outlets (106a, 106b) may be directed to said discharge end (18) of the flare (12));
• and
• wherein the flame front deflector (130) is positioned within the pilot assembly (100) to deflect a flame front FF from said at least one flame front nozzle (36) towards said pilot nozzles (102a, 102b).
