Abstract
A low NO.sub.x staged combustor for a TEOR steam generator includes a primary combustion chamber lined with an improved refractory lining. The refractory lining includes a first layer of low density ceramic fibrous thermal insulation as of 4' in thickness coated on its hot face with a protective coating of a durable tough material. The ceramic fibers of the insulative layer are oriented normal to the plane of the hot face. In one embodiment, a low density castable refractory thermally insulative layer is sandwiched between the shell of the combustion chamber and the first layer of fibrous insulation. In a second embodiment, a low density thermally insulative ceramic fibrous layer is sandwiched between the shell of the combustion chamber and the first layer of fibrous insulation. In the second embodiment, the ceramic fibrous layers are adhered to the shell by refractory hangers embedded in the fibrous insulation and resistance welded to the shell.
