This is a system that produces electrical and thermal power simultaneously on site. CHP, Cogeneration, Distributed Energy are names used for this process.
How It Works
CHP systems use a proven natural gas-fueled engine to generate electricity. Electricity is fed into the building, thereby reducing the facility’s electrical consumption and bill significantly.
At the same time, free “waste” heat is recovered from the cogeneration system’s engine oil, jacket, and exhaust heat. Captured heat is then used to offset fuel that would otherwise have to be burned in the site’s water heaters and boilers. This allows the site’s boilers to not have to work as hard. So the site’s gas bill (e.g., for space heating, domestic hot water/ DHW, process hot water, pool heating, etc.) goes down, too. Waste heat captured from the cogeneration system can even be fed into an absorption chiller, which is able to convert the waste heat into cooling, trigeneration. This relieves the site’s other chillers (typically electric powered) from having to do so much of the site’s air conditioning.
