  • Patent number: 7950919
    Abstract: The invention includes method and apparatus for controlling the stability of a burner, preferably a low NOx burner, of a natural draft heater. The method includes measuring the draft over a time period and generating a measured output from which a draft function is determined that defines the relationship between the draft and time during the time period. A value for the burner stability is defined that is representative of a stable burner operation. The draft function is compared to the stable burner value to determine a differential value, and the operation of the fired heater is adjusted in response to the differential value. The apparatus includes means for measuring the draft over a time period and means for generating a measured output from which a draft function is determined that is proportional to the cyclic variation of the draft during the time period.
