An air preheater (APH) is a general term used to describe any device designed to heat air before another process (for example, combustion in a boiler) with the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperative heat system or to replace a steam coil.
Normal air preheater exist the problem of collection of ash,worn down,low temperature corrosion to effect the safe and economical operation for the boiler unit. So HTEG established the exclusive enamel research and development center to supply the complete solution and organize the scientific reserach personnel to tacle key problems and develop the new heat transfer parts-enameld tubes air preheater
* 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.

Russian Mazut M100 is a fuel oil that is manufactured to GOST specifications, GOST 10585-75 (not active), GOST 10585-99 Oil fuel (GOST is the Russian system of standards, much like ASTM, for example). Mazut is almost exclusively manufactured in the Russian Federation, This kind of oil is graded as the heavy furnace oil. The product is produced from the remains of raw oil processing. This kind of mazut is produced only from the low sulphur raw oil. This product is typically used for larger boilers in producing steam since the BTU content is high. The most important consideration (not the only consideration) when grading this fuel is the sulfur content, which can mostly be affected by the source feedstock. For shipment purposes, this product is considered a dirty oil product, and because viscosity drastically affect whether it is able to be pumped, shipping has unique requirements. Mazut is much like Number 6 Oil, and is part of the products left over after gasoline and lighter components are evaporated from the crude oil. The main difference between the different types of Mazut-100 is the content of sulphur. The grades are represented by these sulfuric levels: Very Low Sulphur is Mazut M100 with a Sulphur content of 0.5% Low Sulphur is Mazut M100 with a Sulphur content of 0.5% Normal Sulphur is a Mazut M100 with a Sulphur content of 1.0-2.0% High Sulphur is a Mazut M100 with a Sulphur content of 2.0-3.5% The amount of sulfur affects how clean the oil burns, and in turn the emissions it creates, as well as the amount of buildup that accumulates within the engines and furnaces that burns it. M100 prices are often determined by its point of origin and mode of production. Apart from shipping charges and regulations, product quality is considered to be more essential. When petroleum is distilled, fuel oil is produced as a residue or distillate. Any fuel oil is a form of petroleum that is burned to produce energy or heat for running an engine. These are usually low-quality oils that are heated in a furnace or boiler and used in a number of industries. MAZUT is such fuel and is typically used in generating plants and factories. Of course, different plants have expected requirements and specifications of their fuel and this is why MAZUT M100/99 and GOST 10585-75 are produced according to industry ISO standards.
