More Power Players

In the Spring 2008 issue of the Dayton Engineer, we asked readers to send us a note about their energy-efficiency projects. Also, a gallery of Kettering Labs construction photos.

In the Spring 2008 issue of the Dayton Engineer, we asked readers to send us a note about their energy-efficiency projects. Here's what they said:

Charles Wolan '63 writes of a project to reduce heating oil used by his home boiler.

I have been living in Switzerland for the 32 years. I am retired from a well-known Swiss Power Generation Co.

I am presently considering and planning privately to utilize the waste heat from the exhaust of my boiler heating system. This is a water preheating system. Instead of cool or cold required water entering the boiler, warm or hot water would enter the boiler, reducing considerably the amount of heating oil that would normally be required.

This could be accomplished by winding a copper tube tightly around the hot exhaust pipe which is about 6 inches in diameter. This copper coil would be connected to the cold water inlet to the boiler. The copper tube would have to be well insulated to use maximum waste heat. Factors such as copper tube size, condensation, water flow, efficiency must be considered.



John Topmiller '88, a performance contracting engineer for Honeywell International, writes, " It was great to read the story on energy-efficiency and renewable energy."

Like many others, Dr. Kissock got me interested in this line of work. I develop energy-efficiency projects for Honeywell focusing on schools and municipalities. For many years my projects have focused on traditional retrofits such as replacing boilers, adding building controls, lighting, etc. However, recently I’ve been overwhelmed with the demand for renewables and LEED buildings. Recently my projects are including biomass boilers, solar panels and wind turbines. It’s an exciting time in this field and the demand for our work will only rise as energy prices continue to increase and as concerns for sustainability grows.
