Book Description

From the Preface
The Clean Air Act Amendments (CAAA) of 1990 significantly affect commercial and industrial combustion devices such as boilers, incinerators, and other burners. Under the new emission regulations already promulgated and those being developed, compliance will require improved equipment, more detailed operator training, new permits, more complex monitoring and reporting, as well as other requirements. All emissions must be considered, e.g., particulates and gases (acid, organic, hazardous, NOx, ozone).
Many industrial boiler plants have been retrofitted to change fuel and/or combustion operating conditions as a means to meet new air pollution control requirements. New regulations will continue to be developed by the CAAA of 1990 that will require changes to other boilers and combustion systems. This book is intended to acquaint industry with the equipment and operating options that are available to reduce emissions while controlling costs. Specific topics are addressed, including regulatory requirements, boiler and burner equipment retrofits, combustion modification, air emission control and monitoring equipment selection, maintenance, and cost. The twelve chapters of this book are written by seven different authors. The authors use fifty-two figures and forty-four tables to help explain the written text and to make it more interesting and useful to readers.
