* 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.
Ramming mass is commonly used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries. Ramming mass is widely used in non-core intermediate frequency furnace and core induction furnace. As an intermediate frequency furnace ramming material, refractory ramming is applied to melt gray cast iron, nodular cast iron, malleable cast iron, vermicular cast iron, and cast alloy steel; to melt carbon steel, alloy steel, high manganese steel, tool steel, heat resistant steel, stainless steel, molten aluminum and its alloys; to melt red copper, brass, white brass, bronze and its alloys, etc. Induction furnaces are used for melting cast iron, mild steel and various alloy steels in foundries and making of steel in mini steel plants using sponge iron The refined high silicon, low iron quartz sand and quartz powder are selected and the fused quartz sand is added as the refractory material., with no slag, no crack, damp proof, convenience of repair, and the corrosion resistance, thus greatly improving the furnace service life span and the economic benefit.. Silica ramming mass can safely be used up to an operating temperature of 1600 deg C. Since it expands very little, it is superior to both alumina and magnesia refractories to resist thermal shocks Acid ramming material is the premixed ramming mass of the lining material. The acid ramming mass is used to smelt a series of metal materials such as ordinary steel and carbon steel. The lining practice best suited to a particular furnace depends upon the capacity and design of the furnace, operation practice adopted during making of a heat, and furnace output.

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.

The average mixing ratio necessary to obtain mortar with good working consistency is 1 part by weight Solution & 3 part by weight powder. The ratio will vary slightly depending on temperature and working conditions.Stir the liquid thoroughly before using. Place liquid in a suitable shallow mixing pan. Add powder by weight in the solution mix thoroughly and rapidly until all lumps are dispersed and the mortar is completely homogenous. Spread out the mortar in a thin layer, not more than ¾ thick, to dissipate the heat of reaction and lengthen the working life. Batch size can be varied depending upon the temperature and the speed with which the masons are working. Very large batches will become stiff quite rapidly. Make sure that all the Furan Motrar is used from the pan before another batch is mixed.When working at temperature above 40 C, very small batches not more than 2 Kgs, should be prepared. When working at temperature below 15C the liquid should be kept warm.
