Auxiliary burner assembly and control system for combusting vent gases in petroleum production and processing

摘要

An auxiliary burner assembly is provided within the exhaust stack associated with a main burner assembly for combusting vent gases from a petroleum production and processing facility. The auxiliary burner unit is located within the exhaust stack associated with the main burner assembly. The 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. An auxiliary burner controller system is utilized to control operation of the auxiliary burners.
