Abstract
A water cooled kiln comprises a cylindrical combustor structure made up of a plurality of generally parallel water pipes spaced circumferentially about the periphery of the structure, and a plurality of webs circumferentially interconnecting the pipes so as to present the cylindrical combustor structure. The webs are provided with openings so that combustion air may flow therethrough and into the combustion chamber defined by the cylindrical combustor structure. The webs are protected from corrosion and erosion by the provision of a protective sheet constructed of a corrosion resistant material which is placed in covering relationship to the web inside the chamber. The protective sheet is spaced slightly from the web by dimples or corrugated strips and is attached to the web by spot welding for example. Air proceeding toward the combustion chamber enters through the opening in the web and is diverted by the protective sheet so that the air flows through the plenum between the web and the sheet and cools both the web and the sheet to diminish the corrosive and erosive effects inherent in the combustion chamber. The diverted air flows through the plenum and enters the chamber about the edges of the protective sheet.
