using pet coke in a rotary kiln as fuel advantage
Project Report on Pet Coke PlantManufacturing Process
The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the coke. The calcined petroleum coke can be further processed in an anode baking oven in order to produce anode coke of the desired shape and physical properties. ADVANTAGES OF USING PET COKE CHALLENGES IN USING PET COKE RECENT Seven different scenaria were developed for the production of 1 ton of clinker in a rotary cement kiln. Each of these scenaria includes the use of alternative fuels such as RDF (Refuse derived fuel) TDF (Tire derived fuel) and BS (Biological sludge) or a mixture of them in partial replacement of conventional fuels such as coal and pet coke.

Use of Pet Coke in Cement Manufacturing and Its Comparitve
As the pet-coke is a high heat value fuel the temperature of the flame increases and hence the heat transfer in the kiln improves. 3. If the alkali contents in the system are high then some sulphur rich raw materials or high sulphur coals are used which may cost more. Jul 15 2020 · The most common method of dosing pulverized coal or pet coke to the kiln main burner is to use a Pfister DRW rotor weighfeeder. A rotary feeder is often installed above the DRW to meter fuel allowing the Pfister unit to be neither starved nor flooded. For accurate weighfeeding the DRW must have a full-head of fuel available to it at all times.

In handling coke and pet coke belt conveyors are often employed after a rotary dryer or kiln. In this setting it is important to select a heat-resistant belt that will not degrade as a result of constant exposure to high temperature materials exiting the dryer or kiln.

Production and Application of Calcined Coke In Rotary
Petroleum coke is usually calcined in a gas-fired rotary kiln or rotary hearth at high temperatures around 1200 to 1450 °C to remove moisture drive off volatile matters increase the density of the coke increase physical strength and electrical conductivity of the material. This coke can either be fuel grade (high in sulphur and metals) or anode grade (low in sulphur and metals). The raw coke directly out of the coker is often referred to as green coke. In this context "green" means unprocessed. The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the coke.
