Many years of experience in several industries have shown that the use of wastes as alternative fuels in cement plants is both ecologically and economically justified. However, there are several factors that need assessment before using alternative fuels. Further, availability and cost are important factors too. Along with other alternative fuels, literature and case studies have revealed that ...

The recycling of zinc in the Waelz process is an important part efficient use resources steel processing cycle. pyro-metallurgical zinc-containing wastes takes place a rotary kiln. Various measured variables are available to monitor process. temperature kiln-shell analyzed by infrared kiln-shell-scanner. In this paper, methods presented which eliminate external weather-related disturbances on k...

The 3M Company incinerates chemical wastes from manufacturing operations in a 23 M kcal/hr (90 MM Btu/hr) rotary kiln incinerator which has air pollution control equipment. This paper deals with the essential features which have resulted in this successful incineration operation for industrial wastes. These features include waste materials handling considerations, design aspects, and main­ tena...

In this paper the effect on energy consumption and pollution of fuzzy automatic control of a rotary kiln is investigated. The computer-based fuzzy control system is installed at the Larko ferronickel plant in Larymna, Greece, by the Danish firm F .L. Smidth & Co. A/S. Operation characteristics for the manual operation against automatic control are defined and compared. Preliminary results show ...

The concept of CCS cluster brings together multiple CO2 industrial emitters using shared capture and/or transportation infrastructure and offers several advantages for network partners compared with point-to-point individual projects. It reduces costs CCS, enables from small volume facilities. proposed connects a sites significant heat demands cement plant through the implementation Ca-looping ...
