Abstract:
1. A burner system for destruction of vapors and a waste water stream containing hydrocarbon contaminants comprising: a generally tubular elongated outer burner element having a sidewall, a front end having an opening, an opposed open back end, and a flange mounted to said front end; a generally tubular elongated inner burner element disposed within and spaced inwardly from said outer burner element, said inner burner element being open at opposed front and back ends thereof, including a small diameter front inlet and a larger diameter combustion zone at said back end; an annular passageway formed between the inner burner element and the outer burner element for bypassing cooling air past and around the flame so that vapors may be consumed downstream of the flame; a vapor duct assembly connected to said front inlet, said vapor duct assembly including a duct portion, and a step plate attached to said duct portion and said flange; a spark igniter connected to said vapor duct assembly and passing through said front inlet and into said combustion zone; at least one fuel ignition device mounted to said inner burner element at said combustion zone; one or more cooling water spray nozzles in said burner system; at least one spray nozzle for spraying said waste water stream into said burner system and to atomize the water component; a bypass opening connected to said step plate in fluid connection with said annular passageway; and a fan located adjacent the front end of the burner system connected to said bypass opening for moving air or vapors into said annular passageway.
