| 摘 要： | 本文首次从闪蒸蒸汽作功出发,推导出多级热水闪蒸汽轮机功率的一般计算式,通过对该式求导得出各级闪蒸热水按等温降分配时汽轮机的最大功率计算式,并与数值迭代寻优值进行比较.本文还求出了多级热水闪蒸汽轮机最大功率与热水全流透平功率之间的关系式,提出了判别多级热水闪蒸与全流透平发电系统优劣的准则式.

| Abstract: | On the basis of the work done by flash steam, a general formula for calculating the power of the steam turbine which adopts the multi-stage flash system of hot water is derived. By differentiating it, an another formula is obtained, which can predict the maximum power when each flash of hot water is distributed according to the principle of isothermal drop. Then, it is compared with the method of numerical iterative optimization. Furthermore, a formula is deduced to express the relation between the steam turbine maximum power flash of hot water and the power of total-flow turbine. Finally, a criteria is presented to determine which system is superior. |
