sep 27, 2020 calcining, also called calcination, is an industrial process that uses very high temperatures, often between 1,,800 degrees fahrenheit or higher, to change the physical and chemical properties of various solid materials, such as minerals, metals, and ore.the origin of the term comes from one of the oldest and most common calcining processes:
the cold end of the kiln is the main gas moving fan. It pulls the combustion products, carbon dioxide from calcining, and the water vapor from the wet mud out of the cold end of the kiln. the ID fan is used to control the total air flow into the kiln for combustion, so controls the excess air or excess oxygen in the flue gas from the kiln.
capacities of industrial calcining tools vary: shaft kilns can yield around tons of finished product per day; the most recent pfr kilns can deliver up to 800 tons per day; modern rotary kilns with vertical preheaters can produce up to 1,250 tons per day. energy efficiency

may 02, 2013 calcining kilns need limestone with proper decrepitation index. decrepitation index of limestone is a measure of its susceptibility to disintegration during calcination. low value of decrepitation decreases the porosity of the bed thus impeding the flow of the gases the kiln efficiency. rotary kilns also need limestone with good tumbling index.
rotary kilns are used to carry out the calcination process. depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or indirect-fired type. It is also common to follow the calcination process with a rotary cooler. this efficiently cools the material after it has been calcined, so it can move on to

rotary calciners. rotary calciners, also commonly called indirect kilns, are used in various calcination operations where exhaust gases must be minimized, when processing finely divided solids, or where temperature must be tightly controlled along the length of the kiln.. calciner is comprised of a rotating drum inside a furnace, which is externally heated.
the rotary kiln system is well suited for converting larger particle sizes and the integration of the cyclone preheater greatly improves specific energy consumption over just a straight kiln. It also reduces the size of the kiln and makes treatment of off gases very simple because the heat is removed prior to treatment.
the rotary kiln is also able to optimize the coke calcining operating parameters, be it residence time, temperature gradient, and heat up rate, all of which impact product quality. coke kilns can be fueled with: gas, heavy oil, oil, refinery gas, waste oil and solid fuel, fired independently or in combination.
