System Benefits of High Efficiency Burners

Posted by Andy Hayes on Feb 11, 2019 9:18:00 AM

The idea of replacing the boilers in an existing central energy plant can be daunting. This is very high capacity, very large, and very pricey equipment. The renovation can take a long time and require extensive modifications to the existing mechanical room.  The logistics of getting the old equipment out and getting the new in is a full project by itself.

How to Combat Iron Oxide in Hydronic HVAC Systems

Posted by Kelly Patterson on Feb 7, 2019 2:07:02 PM

Air in a hydronic HVAC system can be a problem, specifically when it comes to the development of corrosive iron oxide.  When system components, like pump volutes or expansion tanks, made of cast iron or steel are mixed with oxygen and water, corrosive iron oxide is formed.  Commonly known as "black sludge," iron oxide includes magnetite.  Magnetite is a naturally occurring brownish-black or black material that is extremely fine and becomes a black, sticky mess inside hydronic systems.  Magnetite can get into valves and ECM motors.  It can also build up on the surfaces in a boiler or heat exchanger and act as an insulator to reduce heat transfer and system efficiency.

Introduction to Magnetic Bearing Technology

Posted by Andy Hayes on Nov 30, 2018 10:14:04 AM

Conventional commuter trains are generally limited to a top speed of 60 miles per hour.  The train speed is limited by the track condition, curvature, and elevation changes.  It takes a lot of energy to move that big, heavy equipment up and down the track.  Additionally, the train must overcome rolling resistance between the train wheels and the track to get to higher speeds.

energy (n):  Power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.

Our obsession with energy, how to harness it and how to use it efficiently is not a new thing.  After humans first warmed themselves with the sun, they eventually discovered fire.  Early humans used wood fires to cook food and keep warm.  Modern humans still do it in home fireplaces, wood-burning stoves and during camping adventures.
