Biography
Vivek V. Ranade is a deputy director of CSIR-National Chemical Laboratory, Pune, India. His research interests include process intensification, reactor engineering, and multiphase flows. Ranade holds a B.Chem.Eng. (1984) and PhD. (1988) from the University of Mumbai (UDCT), India. He has successfully developed solutions for enhancing the performance of a wide range of industrial processes and has facilitated their implementation in practice. He has also developed various devices (micro-reactors, filters, vortex diodes) and products, and published more than 120 papers and three books. In addition, he is also an entrepreneur and has co-founded a company, Tridiagonal Solutions (www.tridiagonal.com).
Devkumar F. Gupta
is currently a principal scientist at Thermax Limited, Pune, India. His research interest lies in converting solid fuels into high value-added products using fluidized bed reactors. He has had an instrumental role in the design, computational modeling, and establishment of high-pressure gasification demonstration plants in India. He has worked jointly with utility industries to develop computational fluid dynamics (CFD) and reduced order numerical models for pulverized coal fired boilers. He has presented several research papers at international and national conferences on clean coal technology. He holds a Ph.D. (2011) in chemical engineering from the University of Pune, India."This book aims to provide the reader with a pragmatic approach to modeling pulverized coal fire boilers. Because of the importance of improving the efficiency of such systems and reducing CO2 emissions, this book would serve as a good reference text for future engineers engaging in handling pulverized coal fire boilers. The close link between CFD and reactor models represents the unique feature of this book."
—Guan Heng Yeoh, Associate Professor, School of Mechanical and Manufacturing Engineering, University of New South Wales, Sydney, Australia"The book presents an overall view of PC boilers design, operation, as well useful suggestions on their modeling and simulation."
—Prof. Dr. Marcio Luiz de Souza-Santos, University of Campinas
