Abstract:
A sealed observation element (10) for viewing the flow of molten liquid (38) during the operation of a sulfur recovery unit comprises at least one sight glass (14) that is heated and which may be swept with a purge gas supplied through one or more bleed rings (22) to prevent condensation or deposition of materials on the side of the sight glass (14) exposed to the process stream.
Abstract:
A tubesheet protector device (16) is provided for use with a boiler (14) having at least one tube (28) for receiving a fluid extending therethrough. The tubes (28) extend approximately perpendicularly from a tubesheet (34) covering an inlet of the boiler (14). The tubesheet protector device (16) includes insulating board (38) mounted on the tubesheet (34) having holes (36) therein for receiving ferrules (40). Each ferrule (40) includes a shank (42) adapted to be received in one of the tubes (28) and a polygon-headed collar (44) coupled with the shank (42). Both the collar (44) and the shank (42) of the ferrule (40) are wrapped in insulation (46). The collar (44) has dimensions larger than the outside diameter of the tube (28), and the collar (44) and the shank (42) both have a common through bore (14) for transporting fluid from outside the boiler to the interior of the tubes (28) extending through the boiler (14).
