Modern oil refineries and petrochemical plants have dozens of fired heaters, making good heater controls and safety systems fundamental to refinery reliability and energy efficiency. Yet many heaters lack effective air, draft and fuel gas controls and safeguards.
Heaters are a natural opportunity for feedforward. Use feedforward to easily reduce (in many cases, virtually eliminate) outlet temperature deviation. Or, use feedforward to break temperature cycling caused by feed/effluent exchangers.
