Steam engine room arrangement of 1000MW ultra-supercritical primary reheating unit
The invention discloses a steam engine room arrangement of a 1000MW ultra-supercritical primary reheating unit, and aims to overcome the defect that the arrangement cost is increased due to unreasonable arrangement of a steam engine room of a single-shaft reheating unit of the 1000MW ultra-supercritical primary reheating unit in the prior art. A conventional steam engine room is changed into a semi-high-position steam engine room and a low-position steam engine room; the semi-high-position steam turbine room is arranged at the tops of the deoxidizing bay and the bunker bay, and the high-parameter module steam turbine generator unit is arranged on an operation layer of the semi-high-position steam turbine room; the low-position steam engine room and the conventional steam engine room are arranged on a plant terrace, and the low-parameter module steam turbine generator unit is arranged on an operation layer of the low-position steam engine room. According to the method, the length of the 650 DEG C high-temperature pipeline is shortened, the using amount and investment of 650 DEG C high-temperature materials are reduced, and the number of on-site welding seams of the 650 DEG C high-temperature pipeline is reduced; meanwhile, the civil engineering cost is effectively reduced; in addition, the pressure drop of the main steam system and the reheat steam system is reduced, so that the heat consumption of the unit is effectively reduced.
本发明公开了一种1000MW超超临界一次再热机组的汽机房布置，旨在解决现有技术中1000MW超超临界一次再热机组的单轴再热机组的汽机房布置不合理，使得布置成本增加的不足。本发明通过将一个常规的汽机房改为一个半高位汽机房和一个低位汽机房；半高位汽机房设在除氧间和煤仓间的顶部，高参数模块汽轮发电机组布置于半高位汽机房运转层；低位汽机房同常规汽机房，布置于厂区地坪，低参数模块汽轮发电机组布置于低位汽机房运转层。本发明缩短了650℃高温管道长度，减少了650℃高温材料用量和投资，且减少了650℃高温管道现场焊接焊缝数量；同时有效降低了土建费用；另由于减小了主蒸汽系统和再热蒸汽系统压降，有效降低机组热耗。
