Processing depth for AFs06 June 2019, Published under Cement NewsIn his paper ‘A new approach to burning alternative fuels’, delivered at the Cemtech Europe 2018 conference in Istanbul, Turkey, Oral Turesay of KHD Humboldt Wedag introduced the concept of ‘processing depth’. His thesis was that the greater the proportion of the thermal energy requirements to be provided by alternative fuels (AFs), the greater the investments for kiln modification are likely to be. That is certainly the case and has been borne out by many examples from the international cem... |
Impact of alternative fuels27 March 2017, Published under Cement NewsIt is widely acknowledged that burning alternative fuels in cement kilns has some adverse effect on the kiln’s productivity and thermal energy efficiency. But how much effect? Dr Clark explores via benchmarking. Figure 1: kiln meantime between stops (MTBS) Case studies and the technology around the burning of alternative fuels (AFs) in cement kilns are recurrent topics in International Cement Review and at Cemtech conferences. They have also often been the topic of the... |
Coal classification07 November 2016, Published under Cement NewsDr Clark understands that the accepted ways of classifying different types of coal have led to complications when plant personnel have been required to estimate the specific thermal energy consumption of cement kilns. The accepted ways of coal classification are not always useful in estimating the volume of this fuel required to fire the kiln Cement manufacturing is a capital-intensive industry where control of costs is paramount. To recover the capital investment required to... |
