Description
Technical field
The present invention relates to the condensate system boiler circuit of Turbo-generator Set, more specifically it is the condensate system joining weep gland steam heater.
Background technology
There are the following problems for the condensate system of Turbo-generator Set:
Condensate recirculating water pipe road vibrates: in thermal power plant, no matter unit capacity size, parameter height, the vibration of condensate recirculating water pipe road is common phenomenon.Condense water recirculation flow to measure condensate pump and gland steam heater and allow the big person of minimum current.Its objective is during startup and shutdown of units process and underrun: ensure to be not less than the minimum current of its permission by the condensing capacity of condensate pump, to prevent condensate pump overheated and cavitation occurs；Ensure to be not less than the minimum current of its permission by the condensing capacity of gland steam heater, to condense gland leak-off, and make the vapour side of gland steam heater and enter vapour (gas) piping maintenance tiny structure, it is prevented that the seal steam of the high, medium and low cylinder pressure of steam turbine drains in steam turbine building and in lubricating oil system.The condensation water of condenser hotwell enthalpy after condensate pump boosting with gland steam heater heating can raise with temperature, the saturation temperature that the condensing water temperature after intensification is corresponding higher than condenser pressure.When startup of unit and underrun, the lift of condensate pump is higher, during the motor power frequency operation of especially condensate pump, pressure is higher, the pressure reduction that condensation water recirculation adjustment valve bears is big, and selected spool latus rectum is little, condenses water and flows through the flow velocity height at spool place, dynamic pressure is high, lower than condensing the saturation pressure that water is corresponding after heating up, there is vaporization and produce steam and water bursting in static pressure, the boil-off of pressure rise afterwards condenses and cavitation phenomenons occurs again in spool.Condense water vapor, steam and water bursting and cavitation are to condense water recirculation to regulate valve and the main cause vibrated and noise is big easily occurs pipeline.In engineering, method conventional when vibration occurs in condensate recirculating water pipe road is to set up limit to shake support, and this is a kind of passive solution cured the symptoms, not the disease.
Deaerator level control valve vibrates: during startup of unit with load up, the aperture condensing water recirculation adjustment valve turns down closedown gradually, condense water recirculating mass and be gradually reduced to zero, to oxygen-eliminating device main condensate flow by zero to condense the minimum current of water recirculation, the aperture of deaerator level control valve is opened greatly gradually.In the process, deaerator level control valve aperture is less, and the pressure reduction born is relatively big, and adjustability is poor, and spool is susceptible to upper and lower play, runs extremely unstable, can cause deaerator level control valve and connect pipe vibration.It addition, regulate valve design to shroud perforate unreasonable, gap, position is little, water velocity is high for spool in upper and lower play region and some between shrouding, it is easy to vaporization and cavitation occur.Accordingly, it is possible to the noise that association is bigger.Deaerator level control valve and connection pipe vibration thereof are also relatively conventional in Turbo-generator Set factory.
Middle pressure precision processing device superpressure: the pressure condensing water is more high, the resin in precision processing device is more easily broken, and service life is more short.Therefore, the design pressure of middle pressure precision processing device is usually no more than 4MPa (g), and adopts import resin (low pressure precision processing device adopts domestic resin).During the unit operation of subcritical above parameter, some operating mode, especially the motor power frequency operation operating mode of unit band portion load and condensate pump, the condensation water pressure in middle pressure precision processing device is often beyond 4MPa (g).It addition, condensate system superpressure causes accurate process equipment and pipe leakage, affect unit safety operation.Certain 660MW supercritical unit, in order to make the operating pressure of precision processing device less than 4.0MPa (g), open the big water recirculation that condenses and regulate valve, steam and water bursting causes the vibration of condensate recirculating water pipe road acutely, producing huge noise, after running half a year, the energy dissipating blind plate of condensate recirculating water pipe is washed out.
