Abstract
Apparatus for burning a product gas having a low BTU content wherein a single burner is adapted to burn the low energy gas alone with the turndown capability of a multi-burner arrangement. The gas flow is separated into two independent flow streams with one flow stream being exhausted into a primary air stream and the other into a secondary air stream prior to combustion. A common control means responsive to changes in load is provided to modulate the secondary air stream and its associated gas stream whereby at decreasing loads proportionately increased amounts of air and gas are directed through the primary air and gas streams.
