* 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.
Bed material of low ferric high temperature super quality is made out of high quality and super heat duty refractory aggregates of high alumina contents & dense texture. This very special bed material has many special characteristics that made it a perfect material for obtaining smooth and perfect fluidization use in fluidized bed combustion boilers (fbc) and circulating fluidized bed combustion boilers (cfbc).
APPLICATION OF SK-HB K-SILICATE MORTAR : * K-SILICATE is used for jointing Acid Resisting brick in construction of vessels in suited for construction of fume chambers and stacks handling hot, dry Acid fumes and vapors. It is also used for jointing chemical resisting stoneware pipes. K-SILICATE cement is good bedding material for Acid â?? Resisting bricks and tiles. The concrete surface needed protection should be dryed, clean and rough. The bricks or tiles will be set with K-SILICATE cement over concrete surface applied with a suitable an impermeable interliner. When Bedding and Jointing Materials are the same. On the treated surface bricks or tiles are bedded to a thickness of about 6 mm and tamp gently with a wooden piece till the paste squeezes out of joints. The paste that is squeezed out of the joint should be removed by trowel with good finishing. After the mortar of the joint is dryed treat the joints with 20% Hydrochloric Acid Solution by means of brush. A.R.lining should be always in contact with Acid and not with water. Concrete subtract like Floor, Wall, tanks and similar surface should be protected with a membrane of Bitrok Mastic or compound steel tanks should be protected with rubber or PVC subjected to chemical conditions and temperature of chemical media. The Brick lining is recommended over the protective layer of Bitrok Mastic. When Bedding and Jointing Materials are Different. Spread the silicate type mortar about 6 to 8 mm thick on the back of the tile or brick. Press the tile on the bed leaving required space for joints between tiles for bricks. After the bedding mortar is set, fill Mp the joints with specified cement.PRODUCT DATA SHEET FOR SK-HB ( K-SILICATE) MORTAR A general purpose cement for acid conditions Resistant to High & medium concentrations of most of the common organic and inorganic acids except Hydroflouric acid. Recommended where the concentration of the acid is high suitable for high temperature. Unsuited to aqueous solutions, alkaline conditions. PREPARATIONS OF MORTAR : * Measure 1 part by weight of K-SILICATE solution into a suitable mixing pan. * Add slowly and gradually 3 parts by weight K-SILICATE mortar and mix thoroughly to form a smooth mortar. * In hot season very large batches of mortar will become stiff quite rapidly therefore small batches, not exceeding 4 to 8 kgs. Will be prepared. * The cement mortar will be used before it starts setting.
