Abstract: A replaceable inspection plug assembly and method for its use with pressure vessels. The plug assembly comprises a collar seal welded onto a pressure vessel outer wall, and a threaded plug removably threaded into the collar and the vessel wall. The plug has a shoulder portion which is seal welded to the collar. For removal of the plug, the seal weld is first machined away using a special cup-shaped rotary machining tool. The plug is then cooled and contracted relative to the collar, and is then unscrewed and removed. Following inspection of the vessel interior, the plug is replaced in the threaded hole and the plug shoulder portion is rewelded to the collar to provide a structurally-rigid and leak-tight joint without need for subsequent stress relieving the welded joint.

Abstract: A particle classifier apparatus and method for separating coarse particles from a mixture of particles carried in a gas stream, for preferred use in combination with a coal crushing mill. In the classifier, the gas-solids stream is passed through a plurality of internal upper angled fixed vanes for imparting a rotational motion to the particles. The rotating gas-solids stream then flows downwardly past 3-6 pivotable deflector vanes located entirely within the rotating gas-solids stream for effectively separating the larger size particles in the gas stream from the smaller particles. The smaller particles are then carried upwardly by the gas stream, such as coal particles carried by an air stream into a combustion zone of a boiler, while the larger size particles are returned downwardly, such as to a crusher for further size reduction and for recycling the particles through the classifier.

Abstract: A spray liner assembly supported in a pressurized desuperheater header of a steam boiler. The liner is cylindrical shaped and open at each end, and is attached and axially retained at one end to the cylindrical header inner wall by multiple adjustable brackets, and is slidably supported at the opposite end by similar brackets. The liner is also flexibly supported radially at dual points on opposite sides of the liner at an intermediate point along its length with each support using a captured metal ball, so as to provide a radial inward elastic loading to the liner and also permit longitudinal and radial expansion and contraction of the liner within the header.
