Abstract
This invention relates to an improved process for the coincineration of municipal solid waste and municipal sewage sludge by dewatering the sludge, breaking it up into sufficiently small particles and employing oxygen enrichment of the combustion process. These small particles of sludge are introduced into the combustion zone above the grate in the combustion zone but at a distance above the grate no higher than that of the point of introduction of secondary air. This is accomplished without undesired excursions of flue gas flow rate and temperature.
