* 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.

Ceramic roller is a kind of refractory material in roller kiln, as the role of bearing and transmission in the furnace. With the development and production of ceramic, roller kiln is widely used in building sanitary ceramics, daily porcelain and specialty ceramics. The requirements of refractory material used in furnace is continuous improvement, especially for strength and high temperature mechanical properties of roller presented updated requirements. Alumina ceramic rollers is the development trend for ceramic rollers, because they fully meet the various needs of ceramic tile production, with the other advantages which other ceramic roller can not be of. Ceramic rollers project is a key component of modern industrial track kilns, and can transmiss and bear ceramic products at temperatures of up to 1300 °c Special size can be made to your order.
Reaction bonded silicon carbide (sisic) ceramic beams have large high temperature bearing, good oxidization-resistance, serving for 4-5 years, about 15 times no longer than alumina without deformation. The products can be used at high temperature, even higher than 1700C for PSSiC Beams. It is applicable to the load-bearing beams in tunnel kiln, shuttle kiln, roller kiln and other industrial kilns.
