Riser duct connected to calciner suffers often from build-up problems. In riser ducts connected to cyclones, build-ups are usually caused by a venturi effect. This occurs mostly in the curved sections of the duct. The closer the duct is to the 'hot' end of the preheater system, the greater the risk of alkali penetration and refractory spalling.

One of the things you want to avoid is fall-through of coarse material to the kiln. The Pyroclon ® R features a specially-designed restricted connection (or orifice) between the kiln inlet chamber and the riser duct that prevents large particles, such as coarse alternative fuels, from entering the kiln inlet chamber.. This restricted orifice also helps …

Re: Coating formation in Kiln Inlet. Sir hello, if you are looking to minimize build up at kiln inlet and riser duct using a preventing automatic method, i would recommend using air blasters which will be blast plant compressed air at fixed timing (hence every 15 minutes) High pressure water jetting can be stressfull for refractory coating
