Opis

The content of this book originates from 35 years of teaching steam generators to graduate students at the Politecnico of Milan, Milan, Italy, and from 45 years of professional activity in this area rst in industry and then as founder of a design and consulting company. Beforediscussingthecontentofthetextbook, Iwouldliketopresenttherationale for the title. Boilers are machines consisting of steam-generating tubes only, that is, of internal and external tubes where water is transformed into saturated steam. Steam generators or, simply, generators indicate machines equipped with one or more of the following components: superheaters, reheaters, economizers, and air heaters besides the steam-generating tubes that make up the boiler. Finally, those machines with tubes, where instead of water, a diathermic uid ows inside, are also called boilers, for their construction is similar to that of the latter. The above notwithstanding, the term boiler is used even when hot water or superheated water is produced instead of steam. Large systems designed to produce electricity have all components indicated above in addition to the boiler. In medium size systems, some of these components are always present, whereas in small ones a regenerator is frequently and approp- ately included. It is therefore justi ed to use steam generators as title, because it best matches the actual makeup of these systems."

The contents of this book originates from 35 years of teaching Steam Generators to graduate students at the Politecnico of Milan, Italy and from 45 years of professional activity in this area. This book has been written for practising designers, users, and engineers of steam generators in order to guide them through practical problems and help avoiding technical mistakes. Also the academic scientists and university students who are interested in problems of power generation can find useful information.

The first part of the book presents the different types of generators which are installed either in industrial plants like power plants. In particular boilers for energy of regenerative sources are included. Information about the optimized solutions, the energetic saving, and the mistakes to be avoided is given to the designer. In the second section both, the thermodynamic calculation and the fluid dynamics are developed according to rigorous scientific criteria. In this section, the author presents several of his original studies. Finally, optimizing criteria are illustrated and computer calculations are shown according to the calculation criteria that are indicated in the book.
An appendix includes an in-depth analysis of a few topics discussed in previous chapters and a study about finned tubes.
