Sargent reduces its carbon footprint

US based Sargent Manufacturing has implemented Combined Heat and Power (CHP) to simultaneously generate electricity and useful heat.

CHP systems capture excess heat and approach efficiencies of 90 percent compared to 40 percent for a typical power plant. Therefore less fuel is required to produce the same amount of energy.

Sargent, combined hear and powerThe Sargent CHP system utilizes a turbocharged, 800 horsepower, natural gas engine that drives a 535 kilowatt generator. It will supply 20 percent of the Sargent facility’s electricity. The engine exhaust flows through a waste heat boiler which makes steam for processes, heating and cooling. Fuel for the existing boilers is thereby reduced. The engine jacket water cooling system flows through a heat exchanger to preheat the water supplied to the boilers. The engine oil cooling system then flows through a second heat exchanger to provide hot water to the finishing processes.

Annual savings are expected to be in the low six figures based on the current price of natural gas, oil and electricity and pay for itself within two years. Carbon dioxide emissions are reduced annually and the carbon footprint of the facility is lowered.
