The static off-design performance simulating model of advanced steam bottom cycle in combined cycle plant is made with a new concept that temperature blocks are the basic units for Heat Recovery Steam Generator (HRSG)... The static off-design performance simulating model of advanced steam bottom cycle in combined cycle plant is made with a new concept that temperature blocks are the basic units for Heat Recovery Steam Generator (HRSG). At the same time, a new method is necessary for making computer program easily, and computing it quickly and steadily. Then some examples are calculated, including simple pressure, multipressure and reheat structures.Thus we can draw some conclusion about the off-design performances of the advanced bottom cycles, and evaluate them comparatively. 展开更多

Due to its superior thermodynamic performance and advaniages in the field of environment protecting, hydrogen has become a promising alternative energy to fossil fuel. On the basis of previous work, a conceptual design of hydrogen fuel combustion turbine power plant capable of greater than 60% (HHV) thermal efficiency is put forward in this paper.Theoretical analysis and comparison are then described, which results in the basis for the future conceptual design. 展开更多
