Abstract
A compensator, system, and method of controlling airflow through a fired heater or furnace. The compensator has a stationary plate disposed across the burner intake and a movable plate disposed adjacent to the stationary plate that is movable between first and second lateral positions to control the airflow through the intake. In the first lateral position, second openings of the movable plate are at least partially aligned with first openings of the stationary plate, thereby defining a first level of airflow through the intake. In the second lateral position, the second openings of the movable plate are at least partially misaligned with the first openings of the stationary plate, thereby defining a second level of airflow through the intake. The airflow through the intake at the second level is less than the air flow through the intake at the first level.
