Modification in Stacks Design for the Integrated Incinerator–Fired Heater System Using CFD
Abstract
Abstract
In a unique integration of its kind, incinerator hot flue gases are routed below convection section of fired heater for enhanced heat recovery for an ongoing oil and gas field development projects. High degree of flue gas mixing between incinerator and heater flue gases is desired at inlet section of coils in convection section for optimal heat recovery. Also design of stack should take care of required draught in incinerator which operates under forced draught and in fired heater which operates under natural draught mode. Computational fluid dynamics (CFD) technique has been used to verify the stack design and degree of mixing at convection inlet section of fired heater. Result of CFD study called for modification in the equipment. CFD study of modified geometry showed acceptable results. Modification in the equipment at design stage itself saved potential cost and schedule impact which would have surfaced during commissioning of the plant.
