Page 20 - Sustainable On-Site CHP Systems Design, Construction, and Operations

Preface

his book was written to share our collective knowledge regarding this important
technology that literally has been around for centuries. Modern combined heat
Tand power, or CHP, is a proven mature technology that still benefits from
advances in modern science. A technology that is sustainable, and as will be seen, offers
important advantages to reducing total CO emissions. Therefore, this book offers a
2
guide to the issues one needs to familiarize themselves with when planning, designing,
constructing, or operating a sustainable on-site CHP facility and is divided into six
parts:

• Part 1—CHP Basics
• Part 2—The Feasibility Study
• Part 3—Design
• Part 4—Construction
• Part 5—Operations
• Part 6—Case Studies

Part 1, CHP Basics, provides an overview, key definitions and concepts, a discussion
of power equipment and thermal recovery use options, packaged CHP systems, key
regulatory issues and challenges, emission impacts and mitigating control options, the
applicability of CHP systems, and an overview of utility price signals. A study of Part 1
will provide the reader with a good understanding of what CHP is, how CHP can make
a difference in working towards a sustainable future, the choices available when
selecting power equipment, the choices available for heat recovery and beneficial
thermal use, regulatory issues to consider, the emission control options available, and
an overview of CHP applicability.
Part 2, The Feasibility Study, reviews fundamental concepts that are necessary to
plan properly a sustainable CHP plant, to conduct a life-cycle-cost (LCC) analysis, and
to provide for system optimizing. The feasibility study is the point at which key issues
and alternatives are investigated, and plans are optimized. The completed approved
study provides a road map that engineers will follow during the design effort [e.g.,
designing a 1500-kW reciprocating engine generator CHP system with hot water–fired
absorption chillers versus designing a 2-MW combustion turbine generator (CTG) with
a steam heat recovery steam generator (HRSG)].
