Preface

To the Second Edition

In the seven years since I finished the first edition of this book I have had several
opportunities to think about what else this book could include to give operators
more intelligence and tools and therefore better operation of plants. Many ideas were
generated by operators asking questions at classes that I teach regularly for operators to
comply with regulations of the Maryland Department of the environment. Also, while
working with the Testing Subcommittee for the ASME QFO standard and preparing
test questions for the operator’s exam I learned much about the perception of boiler
operators. As a result there are a few changes in this edition that should be fruitful.
I’ve also included guidelines for operation of HRSGs and combined cycle systems
because those plants are increasing dramatically with their higher efficiency and the
increase in natural gas production.
I’ve also grown to understand an increasing need for knowledge about our
environment and how our operations affect it. So, there’s more stress in this edition
on the environmental effects of boiler operation.
Because so many boiler plants include chilled water or can include refrigeration
equipment for plant stores, and boiler operators are called upon to operate that
equipment, I’ve also included a chapter on refrigeration systems. One section of the
chapter addresses the environmental effects of inadvertent and intentional discharges
of some of our refrigerants. It does not, however, include all the information that’s
essential for passing an examination to achieve EPA certification for air-conditioning
and refrigeration technicians in accordance with section 608 of the federal clean air act.
There are several short courses available for operators to take for that examination and
they are normally accompanied by the exam.
Finally, because it’s apparent that many Operators are expected to control and
maintain heating and air conditioning systems the refrigeration chapter includes
guidelines on air conditioning.
I do hope this new edition will help you better understand the importance of
wise operation of boiler plants and associated facilities.
