Another significant driver—in a world now more environmentall conscious than ever—is a global thrust to develop projects whic not only minimize GHG emissions but also help to displace GHG emissions from other industrial sources. Thus, one of the more significant advantages of gas-turbine and engine-based cogeneration is the potential for significant GHG reductions. Further, it is the monetization of GHG reductions and other poss financial incentives that are helping to encourage and facilitate development of cogeneration applications. Gas Turbine Power Enhancements The gas turbine is an air-breathing engine that responds to the mass flow entering its compressor. For constant speed units, the gas turbine output will generally vary in.
