Investigation of Combustion and Thermal-flow inside a Petroleum Coke Rotary Calcining Kiln with Potential Energy Saving Considerations

Calcined coke is a competitive material for making carbon anodes for smelting of alumina to aluminum. Calcining is an energy intensive industry and a significant amount of heat is exhausted in the calcining process. Efficiently managing this energy resource is tied to the profit margin and survivability of a calcining plant. To help improve the energy efficiency and reduce natural gas consumpti...

Investigation of Potential Benefits of Using Bricks of High Thermal Capacity and Conductivity in A Rotating Calcining Kiln

Petroleum coke is processed into calcined coke in a rotary kiln, where the temperature profiles of flue gas and coke bed are highly nonuniform due to different flow and combustion mechanisms. Motivated by saving energy costs, the effect of refractory brick's thermal properties on potential energy savings is investigated. This study focuses on investigating potential energy savings by replacing ...

Simulation of Combustion and Thermal-flow inside a Petroleum Coke Rotary Calcining Kiln, Part 1: Process Review and Modeling

Calcined coke is an important material for making carbon anodes for smelting of alumina to aluminum. Calcining is an energy intensive industry and a significant amount of heat is wasted in the calcining process. Efficiently managing this energy resource is tied to the profit margin and survivability of a calcining plant. To help improve the energy efficiency of the calcining process, a 3-D comp...

Study on Pore and Surface Development of Activated Carbon Produced from Iranian Coal in a Rotary Kiln Reactor

Linear Identification of Rotary White Cement Kiln

Rotary cement kiln is the main part of a cement plant that clinker is produced in it. Continual and prolonged operation of rotary cement kiln is vital in cement factories. However, continual operation of the kiln is not possible and periodic repairs of the refractory lining would become necessary, due to non-linear phenomena existing in the kiln, such as sudden falls of coatings in the burning ...
