Like wax candles, Rouseki (Pyrophyllite) is white and semi-transparent, and has a waxy texture when touched. It is very brittle, and tends to crack largely along the stone joints. Up close, this stone looks grayish white, but may look blue from a distance. The ore looks so similar to pottery stone ore that they cannot be distinguished. But there is a difference in their texture, color, and how they crack, and with experience, their differences become more visible. They not only look and feel different, but their applications and properties also differ significantly. It's used as Firebricks, crucibles, glazes, fire-resistant powders, etc.
* PHOSCAST Phoscast : Phosphate Bonded Castables * PURPOSE customers using FBC boilers (Particularly underbed feed FBC boilers) for the protection of inbed coils against erosion potential by applying highly abrasive resistant refractory on inbed coils above fuel feed system. BACKGROUND * Two of such actions are providing special alloy studs on inbed coils and applying highly abrasive resistant refractory on the outer bottom loops of inbed Coils which are above the fuel feed nozzles. * GANESHAS has taken number of approaches to identify the key factors affecting erosion rates with an objective to enhance the life of inbed tubes as well as implementing the corrective action to reduce the erosion rates. Phosphate coatings are often used to protect steel parts against rusting and other types of corrosion * Erosion of inbed coils in fluid bed combustor is unavoidable phenomenon however the rate of metal wastage and thus the life of tubes depends on various factors like ash & fuel properties, design of Combustor / feeding system, flue gas velocities operating conditions etc. It has been also observed that maximum erosion prone inbed coils are those which come above fuel feed nozzles and an area of approximately 1 to 1.5 mts around fuel feed systems are badly affected. APPLICATION Phoscast-90 XR can be applied by ramming with wooden mallet having adequately large head @" dia x 5" length x 10â?? Jong handle). The desired lining or repair thickness is built up in several courses while ramming the mass to uniform thickness. Phoscast refractory should never be trawled to obtain smooth surface; ramming only should finish surface. Any excess mass is to be sliced off with trowel edge and then finished by ramming again for bed coil. Tube application of AFBC boiler, the material pasty mass should be finger pressed into the studs of the tube with maximum force. Finish should be given by pressing the hand palm against material applied, using surgical type thin rubber hand gloves.
