C. B. Oland is the author credited on Guide to Combined Heat and Power Systems for Boiler Owners and Operators by C. B. Oland, a 2004 Oak Ridge National Laboratory report prepared for the United States Department of Energy. The verified byline uses initials; the report supplies the scientific attribution without requiring an inferred full name.^[ref]

The report explains how a facility can obtain both useful heat and electrical or mechanical power from a shared fuel input. Its steam-turbine discussion distinguishes backpressure and condensing arrangements, and defines turbine isentropic efficiency through actual versus ideal enthalpy drop. For example, a 400 kJ/kg actual drop compared with a 500 kJ/kg isentropic drop gives efficiency $0.8$. The useful heating output remains a separate energy stream, so electrical efficiency alone does not describe the complete installation.^[ref]
