The book is biased toward thermal and process design aspects of packaged boilers and HRSGs.The emphasis on thermal engineering aspects of steam generators reinforced by hundreds of worked out real life examples pertaining to HRSGs and related systems will be of interest to engineers involved in a broad field of steam generator related activities such as consulting,design,performance evaluation and operation.
During the last three decades I have had the opportunity to design hundreds of package boilers and waste heat boilers for a variety of applications,which are in operation in the US and abroad.
Based on my review of hundreds of specifications, I feel that consultants,plant engineers,contractors and decision makers involved in steam plant development often fail to appreciate some of the important and subtle aspects of design and performance of steam generators and HRSGs. These are brought out with theory and examples in this book. To name a few topics...
-does raising gas temperature at economizer help avoid low temperature corrosion if water temperature is below dew point?
-is generating steam more efficient in fired HRSGs or in boilers?
-can surface areas be lower while transferring same or more energy?
-how to select fin configuration? Why superheater should have smaller fin density compared to evaporators or economizers?
-predicting temperature profiles in boilers and HRSGs at various loads
-recent trends in package boiler designs
-how custom designing minimizes operating costs in package boilers
-designing a boiler/ superheaters for operation at different steam pressures
-optimizing temperature profiles in multi-pressure HRSGs
-why steaming is likely in HRSGs and not in steam generators
-specifying steam generators and waste heat boilers
-efficiency of combined cycle & cogeneration plants at various loads
-transient operation of boilers
-why smaller tube size decreases length of fire tube boilers
-inline vs staggered arrangement in bare,finned tube bundles
-conversion of NOx,CO from lb/h to MM Btu basis in boilers,HRSGs
-circulation calculations in fire tube and water tube boilers
-a quiz on boilers and HRSGs   and more!
