Power units with the union of the locking-control valves on the lines of the steam supply to the steam turbine and with stop valves on lines RESET steam in condensers

摘要

The invention relates to the field of power engineering and can be used in new construction, renovation and modernization of power units with steam turbine and combined cycle power plant (CCPP and PTU). The energy unit comprises a steam turbine with cylinders of high, medium and low pressure CVP 3, IPC 4, LPC 5 and capacitor 6 and the lines 20, 23, 11 for supplying to said respective pressure steam turbine (HP, MP, LP) from the shut-off control valves installed at least 20 supplying line pair WD, line 22 discharging vapor at promperegrev and at least one high-speed-reducing cooling unit (BROU) connected at least to the line 20 and connected at the output to said capacitor 6 or with the line 23 hot s reheat thread with discharge lines 26, 27, 28. The difference: conductivity of steam shut-off and regulating valve is formed as one for each line 20, 23, 11, a combined trip-IBS-regulating valve 21, 24, 25 and each bleed line 26-28 or on unifying their common bleed line 26 or 27 to a capacitor 6 is further installed shutoff valve 34 1 .. n. f ly-8-yl.
