ASHRAE Transactions - The Alliance to Save Energy called this a "seminal article".
(
We had to look it up. Seminal = Highly influential in an original way.) This article
presents actual energy and performance improvements, and HOW they were
accomplished. Not just the technical, but the "people"  side as well.

quality and applies to the steam user. If steam arrives at the user all wet, perfect
steam from the boiler becomes meaningless. Why does steam get dirty and wet,
and how to find the sources of poor quality.

by Walter T. Deacon                                                           Click here to DOWNLOAD a PDF
Chemical Processing Magazine  - Air and non-condensible gases in steam behave
in peculiar ways. They are heavier than steam, but steam velocity can push them
around. Trapping and venting large AUTOCLAVES has to take this behavior into
account, or poor temperature control will result.

Testing Traps pays Dividends                                        Click here to DOWNLOAD a PDF
by Walter T. Deacon
Plant Services Magazine - Temperature, sound, and visual methods of steam trap
testing have varying effectiveness. For example, temperature can tell when a trap is
failed closed, but NOT when it is failed open. All methods need experience to get
around each shortfall, and they work best in COMBINATION.

Preventing Frozen Steam Coils

focuses on a hospital steam vent problem. It explains how an roof vent line would
spew steam and water... but only intermittently. Where was it coming from? How did
a backwards check valve figure into the solution, and get the problem solved?

Important Considerations in Computer Room Humidification
by W. T. Deacon
ASHRAE Transactions - This article applies to any humidifier moisture problems. It
explains how a humidifer can cause wet spots on the air side alone. Two good
solutions presented can also be applied to operating rooms, animal research
areas, or any air stream with typical 55F temperatures.
