| Abstract: | 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. |
