The ash fusibility is one of the vital measurement to test the high temperature characteristic of coal. It is an important indicator of coal, which reflects the dynamic change of mineral matter in boiler. Therefore, testing ash fusion temperatures of coal plays a critical role to ensure the safe and economic operation of boiler in coal-fired power plants.
– Co-firing with oil / coal / gas • Total world production approx. 80 MM MTPA vs coal market 6500 to 7000 – Higher caloric value (can be as high as 75%) – Lower ash content – But higher sulfur content compared to coal – Particularly attractive in cement/lime kilns which operate at higher temperatures and SO

Coal fines are usually prepared by air swept coal mill or vertical mill. In order to produce high-quality clinker, the fineness of coal fines should be controlled at about 12%, and its moisture content should be controlled within 1.0%. The machines that are usually used to dry the coal fines are rotary dryers.
the temperature increases. Concurrent with this phenomenon, thermal decomposi- tion occurs and gas evolves. The addition of a gaseous phase to the solid and liq- uid phases complicates measurement of coal properties, and the methods of measur- ing plasticity are consequently empirical. Numerous laboratory tests have been de- signed.
Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
