Refinery natural draft fire heater
Web15. aug 2024 · In natural draft fired heaters, the draft is created by the “stack effect” such that colder combustion air is drawn into the burners as the hotter and lighter (buoyant) flue gases are removed from the stack. In modern radiant-convective fired heaters, a damper is typically provided on the stack. WebThe air supply for a gas-fired, natural-draft heater consists of two portions primary air and secondary air. (In some newer burners, tertiary air is used to control nitrogen oxide emissions .) The primary air is educted or sucked into the burner through a venturi by the rapidly flowing fuel gas.
