There are various types of fuels available for external fired rotary kiln, it can utilize natural gas, fuel oil, electromagnetic heating, resistance heating, or silicon carbide rod heating, 3 main types of fuels are: Gaseous fuels such as coal gas and natural gas. Liquid fuels such as diesel and crude oil. Solid fuels such as coal and coke.
In this paper, based on analysis of the chemical and physical processes of clinker formation, a heat flux function was introduced to take account of the thermal effect of clinker formation. Combining the models of gas−solid flow, heat and mass transfer, and pulverized coal combustion, a set of mathematical models for a full-scale cement rotary …

The latest evolution in cement kiln burner technology. Our JETFLEX 2.0 cement kiln burners offer a high degree of fuel flexibility. Use pulverised coal or petcoke, anthracite, oil, natural gas – or any mixture of these – as well as alternative fuels (such as plastic and wood chips, sewage sludge). The results are the same.
The first were simple shaft kilns, similar in construction to blast furnaces. These are counter-current shaft kilns. Heat consumption as low as 4 MJ/kg is possible in the lime kiln. Modern variants have been developed to reduce energy costs and to increase productivity such as regenerative and normal shaft kiln with different modifications. 4.1.
The cement rotary kiln. When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln. We are AGICO, a professional cement equipment manufacturer and cement plant contractor.
