On this basis energy and fuel characteristics of the cogeneration unit are calculated. It is shown that total fuel efficiency increases with growing of heat generation and decreasing of the air surplus coefficient in gas turbine, which determines the range of regulation of partial heat loads. The NOx emission decreases in two times, and the CO emission - it ten times. Specific fuel flow rate for power generation changes from 150 to 240 g c. e./kW(h for air surplus coefficient 6. Base on example of industrial technology, the high-level economical benefits from construction of cogeneration unit are demonstrated that may provide completely this enterprise with cheap electricity and reduce production costs by 25%. The principle technology and design aspects of cogeneration unit are solved. Product Description popup.authors popup.nrat_date 2020-04-02 Close
