During concrete use, there is in contrast correlation technique starting method during high row's ventilation system, illustrate the Unit Commitment method of operation of the present invention.
There is in correlation technique high row's ventilation system, its detailed process realizing the effect avoiding high-pressure cylinder temperature too high in specification background technique is as follows: the Starting mode of correlation technique is intermediate pressure cylinder start-up, the machine simplified process of opening is: boiler water filling → height, low voltage bypass is opened, each high pressure main inlet throttle-stop valve, pitch closedown → ignition of the boiler, heating coil → master, reheated steam pressure, temperature reaches red switch required value → close low side valve → high-pressure main throttle valve, pitch is closed, intermediate pressure main stop valve standard-sized sheet, unlatching high row ventilation valve → press pitch to carry out red switch in opening, raising speed, this process high-pressure cylinder not admission, rotate for preventing high-pressure cylinder internal cause rotor high-speed and produce air blast friction and overtemperature, high-temperature gas in high-pressure cylinder is discharged by opening high row's ventilation valve, this process need comes into operation high row's ventilation system.
In the present invention, do not use high row's ventilation system, be senior school biology by adjustment unit Starting mode, solve this problem, the machine simplified process of opening is: boiler water filling → height, low voltage bypass is opened, each high pressure main inlet throttle-stop valve 14, middle pressure pitch 15 closes → ignition of the boiler, heating coil → master, reheated steam pressure, temperature reaches red switch required value → close high side valve 10, confirm that reheat pressure is after 0, close low side valve 11 → intermediate pressure main stop valve 14, middle pressure pitch 15 standard-sized sheet, high-pressure governing valve 13 standard-sized sheet → carry out adjustment red switch by opening high-pressure main throttle valve 12, high row's non-return flap 7 is opened after raising speed → red switch, intermediate pressure cylinder 5 admission simultaneously, this process does not need the high row's ventilation system that comes into operation.
Have high row's ventilation system in correlation technique, it is as follows that it realizes the detailed process that " when unit tripping, under height row non-return flap fits badly situation, this valve is opened and prevented unit from exceeding the speed limit " in specification background technique act on:
1) regular program shutdown at sliding parameters, fall parameter and shut down unit load, parameter and slowly decline, do not need to use high row's ventilation system.
2) unit emergency shutdown situation, origin operation is high pressure main inlet throttle-stop valve, pitch, the respectively non-return flap that draws gas are closed rapidly, and low side valve opens venting reheaing steam pipe pressure, and high side valve opens venting main steam conveyance conduit pressure.Because high pressure turbine by Guan Yugao discharge pipe is connected, high discharge pipe can be made to there is certain pressure, if high row's non-return flap is not closed completely, the main steam of high parameter drains into high discharge pipe from high side valve, be back to impulsion rotor acting in high-pressure cylinder, high row's ventilation valve can be opened in this case and carry out pressure release.
In the present invention; do not use high row's ventilation system; solution is: after unit emergency shutdown; high side valve 10 is not opened; main steam conveyance conduit 2 Safety valve 17 and Pcv valve 18 is utilized to carry out pressure release; solve high discharge pipe problem with pressure, prevent steam from passing through high row's non-return flap 7 and return acting to high-pressure cylinder 4, high row's ventilation system can be optimized.
Compared with correlation technique, avoid in technological scheme disclosed by the invention and use high row's ventilation system, therefore avoid because it leaks the adverse effect produced, can leakage be reduced, improve unit economy.
Above-described is only embodiments of the present invention, it should be pointed out that for the person of ordinary skill of the art at this, without departing from the concept of the premise of the invention, can also make improvement, but these all belongs to protection scope of the present invention.
