EBOOK - Boilers for power and process (Kumar Rayaprolu)


This is a practical desk bookon water tube boilers for practicing engineersand a reference book for students of heat and power. It has been written by an experienced boiler professional with an all-round technocommercial background of nearly four decades. Let me hasten to dispel a possible interpretation of a “practical book” as a book dealing with only nuts and bolts. On the contrary, this book delves into the theoretical aspects required for a practicing boiler engineer. It tries to recapitulate and build on the forgotten fundamentals of a busy power engineer, providing a higher level of understanding and a wider exposure to various modern boiler and firing technologies.
This book, after providing a brief (but deep) theoretical background of scientific topics involved in boiler technology (namely, heat transfer, fluid flow, combustion, fuels, water, and materials) goes on to describe the different contemporary construction details and thereafter elaborates on the various industrial and utility boilers based on the different combustion systems. Profusely illustrated with design and practical data, it is positioned as a desk book for any boiler engineer, and is meant to be consulted every now and then. Reader friendliness is most essential for a technical book that covers a lot of ground.

There is a lot of design data provided in this book through charts, graphs, guidelines, and comparisons, which are needed by a reader. To make referencing easy, such data are collated and presented as lists of references and useful data in the front matter and appendices that definitely add to the utility of this book for beginners as well as the experienced.
