What is ETC?
Electric Turbo Compounding (ETC) technology is our solution to the challenge of improving energy efficiency for the stationary power generation industry
Increased efficiency for the power generation industry
At Bowman, we believe there is a strong environmental and economic duty to ensure that, where reciprocating engines are used to generate power, fuel is consumed as efficiently as possible. Electric Turbo Compounding (ETC) technology is our solution to the challenge of improving energy efficiency for the stationary power generation industry.
The use of fossil fuel based power generation, particularly in developing economies, is predicted to continue for decades. This is at odds with the global need to reduce carbon emissions, of which, a high percentage is produced by the power sector worldwide.
Our ETC products make gas and diesel-powered gensets work more cleanly and effectively, by recovering waste energy for the genset exhaust to improve power density and fuel efficiency. The technology is equally suited to new-build and retrofit applications, for engines in the 150kW-2MW range. Dependng on engine size, either a single or twin ETC system will be required – see below. We have also developed ETC products for much larger engines with a waste gate, such as the Wärtsilä 34SG, a 9MW gas engine. Read a case study.
