ABSTRACT:
A low NOx gas combustor includes an air injection mechanism to create a combustion air path. A set of arc-shaped gas injector arrays are formed in an annular configuration. Each arc-shaped gas injector array injects an arc-shaped stream of gas that intersects with the combustion air path to produce a fuel rich flame segment that is separated from an adjacent fuel rich flame segment from an adjacent arc-shaped gas injector array by an air rich zone. The interaction between the fuel rich flame segment and the air rich zone results in low NOx combustion of the gas.
