Johnny Tundra--Cold Weather Engineer
It was a brisk February morning and Johnny Tundra, the engineer from Big Timber, was on the road to Angela, Mont. The wind was kicking up a bit across the prairie, sweeping the snow across the highway in blankets of undulating white. The sun was bright enough to blind, and inside Johnny's International Harvester Scout station wagon it was easy to forget the outside temperature, failing to make it above zero....
District-Steam Design for University Campuses
A district steam system consists of at least one steam boiler, a fuel system, a feedwater system, a flue-emissions-control system, a boiler-control system, a condensate-return system, and a steam-distribution system. This article will discuss steam-distribution-system design outside of a boiler plant, focusing on data collection, preliminary engineering, and detailed engineering. A university replacing building- dedicated steam boilers with a campuswide district steam system will be used as an example....

Shocking Problem
The old strip heat was removed, the wires were abandoned in the walls, and the circuit breakers were to be removed, disabling the old system. The boilers were installed in outbuildings serving 25 separate apartment buildings. A premanufactured polyethylene-insulated pipe assembly connected the boilers to the copper heating-hot-water circuits in each building. ...
Shocking Problem
A project I was managing in a 120-unit apartment complex involved the replacement of electric strip heat with hot-water baseboard. The old strip heat...
