Steam turbine power plant for executing the operational manner and its manner of steam turbine power plant

摘要

(57) Abstract This invention is something regarding steam power field, both of the steam turbine power plant of re-heating die and fault re-heating die is active ones the case of the adjustment with the introduction of addition steam re-heating. Summary of this invention is as follows. The offering/accompanying water supply heating pump and the low pressure cylinder with 4 which are jointed the re-air heater by bypass line 8 of the aforementioned re-air heater 5 which possesses 5 which is jointed boiler 1 and high tension and medium pressure, by the turbine and that turbine and the pipe arrangement 6,7 which consist of the low pressure cylinder 2,3,4 and valve 9 and generator 10 and condenser 11 and water pump 12 and aforementioned boiler 1 and pipe arrangement 14 and bypass line 8 in pipe arrangement 7 distribution facilities the steam mixer 15 which is done and bypass line 8 and with re-air heaters 5 in pipe arrangement 6 distribution facilities the steam turbine which has with the valve 16 which is doneIn the power plant, the cool steam where the case of operating condition of rated other steady states, the high tension cylinder it comes out 2 and the intermediate cylinder 3 is divided by two currents, these two flow is distributed by valve 9,16 and is as follows sent. The 1st flow of 90 - 50% tonnage inside the steam current which comes out of the turbine was sent to bypass line 8, with the cool steam current where 10 - 50% currents other than that were sent by re-air heater 5, with largest pressure 0.1 - 1MPa were heated to temperature 650 - the 850 in that re-air heater 5, that the steam current which re-is heated and the bypass were done being combined, it becomes one steam, current after being mixed inside steam mixer 15, it is supplied to the turbine. As for this invention, it is efficiency of the steam turbine power plant and something which improves reliability by designating the moisture content expansion process inside the turbine in lastly as zero.
