COMBUSTING VENT GASES USING AN AUXILIARY BURNER

摘要

A method and apparatus for controlling an auxiliary burner assembly for combusting vent gases is provided. An auxiliary burner is provided within the exhaust stack associated with a main burner assembly for combusting vent gases from a petroleum production and processing. The auxiliary burner is located within the exhaust stack associated with the main burner assembly where only one burner is utilized at a time. The integrated auxiliary burner assembly enables the same exhaust stack as the main burner assembly while effective combusting exhaust gases and providing heating of a medium when required. The auxiliary burner is utilized when the main burner assembly is inactive and gas pressure stored in a vent gas tank exceeds an upper pressure set-point value.
