Abstract
A burner system for a furnace includes horizontal rows of cell burners some of which contain a secondary air port vertically spaced from a coal nozzle. The cell burners are in the front and rear walls of the furnace. Near the side walls of the furnace, which are connected between the front and rear walls, additional double-burner cells are provided which include a pair of vertically spaced coal nozzles or burners. Either a single lower row or a lower and upper row of cell burners include the double-burner cells at the side walls. The double cell burners are operated at 1.0 or higher throat stoichiometry. This reduces corrosion at the side walls while only slightly increasing NO.sub.x emission.
