tailieunhanh - Interactions of Chemical Variations and Biocide Performance at Paper Machines

Vertical shaft kilns are still used in some parts of the world to produce cement, predominately in China where they are currently used to manufacture nearly half of the cement produced annually (Wang 2007). A shaft kiln essentially consists of a large drum set vertically with a packed mixture of raw material and fuel traveling down through it under gravity. Parallel evolution of shaft kiln technology with the more complex dry process rotary kilns kept the mix of pyroprocessing technologies in China's cement industry more diverse than in almost any other country. Coal is the primary fuel burned in. | CỌ s Department of Forest Products Technology w z o Jani Kiuru Interactions of Chemical Variations and Biocide Performance at Paper Machines Aalto University Aalto University publication series DOCTORAL DISSERTATIONS 148 2011 Interactions of Chemical Variations and Biocide Performance at Paper Machines Jani Kiuru Doctoral dissertation for the degree of Doctor of Science in Technology to be presented with due permission of the School of Chemical Technology for public examination and debate in Auditorium Puu2 at the Aalto University School of Chemical Technology Espoo Finland on the 20th of January 2012 at 12 noon.
