Why Cogeneration ?

Industry continues to seek innovative solutions to the dual dilemmas of ever-tightening environmental regulation and ever-increasing fuel costs. Modern gas turbine technology has made enormous progress towards the related goals of reducing emissions and improving efficiency, but even these modern plant designs may suffer heat losses in excess of 70% unless Cogeneration techniques are employed.

An environmentally and economically sound method of "thermal recycling", Cogeneration captures the excess thermal energy contained in exhaust gases. A unique type of heat exchanger or heat recovery - high temperature water heater (HR-HTWH) is placed in line with the exhaust of a gas turbine, producing significant amounts of high temperature water (or steam) by using the hot exhaust gases in place of a boiler flame.

This "waste" heat would be lost "up the stack" in more conventional designs, but with a Cogeneration plant design, exhaust gases are not allowed to escape until all excess thermal energy has been recovered. Commercially supplied natural gas, which is a mix of naturally occurring methane and mercaptan, the compound added to give that distinctive "natural gas" smell, is typically used as the primary fuel source. The use of clean-burning natural gas, coupled with the efficiency inherent in a Cogeneration design, yields an independent power plant which produces electricity and hot water or steam at high efficiency while producing negligible emissions.
