اقرأ المزيدAbstract The challenging problem of improving the control of a rotary coke calcining kiln is discussed. An overview of works on simulating such kilns is presented, a mathematical model of the technological process for use in a control system is proposed, and approaches to developing a control system in the SimInTech environment are …
اقرأ المزيدThe aim of this work was to establish a mathematical model for the analysis of calcining process of petroleum coke in a 24-pot calciner via computational fluid dynamics (CFD) numerical simulation method. The model can be divided into two main parts (1) heterogeneous reacting flow of petroleum coke calcination in the pot was simulated …

اقرأ المزيدRSS Dixie has numerous products installed in coke calcining plants across the country. ... The firing hood, ... The settling chamber and stack are upstream from the green coke feed. The stack in many plants is typically gunned or shotcreted.
اقرأ المزيدCoolers receive hot material (clinker) discharged from the kiln and cool it as it is conveyed to handling and storage systems. To cool the clinker, ambient air is blown via fans up through the porous floor of the cooler. The service environment of the cooler is extremely abrasive, subject to wide swings in temperature and alkali attack.
اقرأ المزيدIn a precalciner kiln, changes in the kiln feed carbonate concentration should result in changes in the fuel rate or in the degree of calcination of kiln feed from the calciner, assuming the temperature and residence time in the calciner are not changed.In long kilns, both wet and dry, the calcining zone is in the rotary kiln; consequently ...
اقرأ المزيدThe thermal diffusivity of petroleum coke decreased during the calcining process. With increasing temperature, coefficient of heat conductivity and specific volume heat of the petroleum coke increased with a decreasing variation rate. The research provides a database for the calcining graphitization process of petroleum coke.
اقرأ المزيدPetroleum coke, or "petcoke," is a waste by-product of the oil refining industry. The majority of petcoke consumption is in energy applications; catalyst coke is used as refinery fuel, anode coke for electricity conduction, and marketable coke for heating cement kilns. Roskill has predicted that long-term growth in petroleum coke …
اقرأ المزيدCalcined petroleum coke is used for the production of carbon anodes in the Hall-Héroult aluminum smelting process due to a combination of low impurity levels, ready availability, and relatively low cost. This article provides a review of the history and use of calcined petroleum coke for anode production and describes the different calcining …
