摘要
In the paper classification of dual-fuel combined cycles was made. Main marks and characteristics of components of the specific couple structures were contained. Selected conceptions and preliminary research results of parallel-couple combined cycle supplied by hard coal and natural gas, which steam part works in supercritical parameters (30 MPa, 600 degrees C) are shown. We can state that even small gas turbines (power ratio 1/10) coupled with steam cycles increases efficiency of electricity generation about 1.5% in result.
