ABSTRACT:
A plant gas to be flared in the atmosphere is periodically sampled and analyzed as to its Btu content, a first comparison made of 1) the most recent of such analyses with 2) a predetermined steady state set point, a second comparison made of 3) an average of a plurality of such analyses including an historical minimum Btu content with 4) a predetermined dynamic set point, and fuel added to the plant gas based on the larger fuel requirement of these first and second comparisons.
