| Abstract: | The development situation of power unit with double reheat cycles of thermal power plant are briefly introduced and the power unit with the capacity of IO00MW is cited as an example in this paper. The technical characteristics of ultra-supercritical unit with double reheat cycles is elaborated in three aspects such as selection of unit parameter, main machines and main thermal power system. A comparison between the economy of 1000MW ultra-supercritical unit with double reheat cycles and that of IO00MW ultra-supercritical unit with single reheat cycle is made in the two aspects of coal consumption rate and variation in investment. The proposal concerning the technical application of ultra-supercritical pressure power unit with double reheat cycles is also set forward. |
