*GENERAL DESCRIPTION

-For the conversion of thermal energy into mechanical power, the turbine receives superheated steam and injection

  steam from a boiler.

-The enthalpy drop of the steam across the numerous stages of the turbine is transformed into energy in a continuous

  process.

-The steam flows through the emergency stop valve, the HP control valves and through the blading and to the

  condenser.

-The live steam line is provided with drains to prevent wet steam from entering the turbine.

-Strainer located in front of the emergency stop valve protects the turbine blading from being damaged by hard

  particles carried along in the steam.

-The exhaust duct and housing are guarded against excessive pressure by pressure feelers.

-The turbine is furnished with a number of drains to remove the condensate during the condensing phase of the

  start-up.

-To protect the steam pressure transmitters from a direct contact with steam, condensate slings are installed in the

  line to them.

*GRAND SYSTEM

-The turbine labyrinth bushings are furnished with two branches.

-The inner branches are connected to seal steam supplied from live steam pipe via a pressure reducing station

 (live steam pressure reduced to app. 0.03 kg/cm2;g and desuperheating station

-The outer branches are connected to the grand steam condenser where the steam condensates and air is

  exhausted by a fan into are atmosphere.

-The gland steam system consists of these components:

 1. The gland steam condenser the parts of which are:

            -a cylindrical shell with tube plates on both sides and with a tube bundle;

            -cooling water chests with water inlet and outlet branch' cooling water flows through the condenser tubes;

            -a steam inlet nozzle through which the steam - air mixture flows from the glands into the condenser

              (outside the tubes)

 2. The exhaust fans mounted on the condenser and exhausting the air from condenser to the atmosphere

     (one fan is stand by)

\\NOTE : In emergency cases (fall-out of exhaust fan) it is possible to open the valve from steam-air mixture

                  piping directly to the atmosphere (this valve if normally closed).

  !!! Never allow the gland steam to enter the condenser without minimum cooling water flow - danger of tube damage!

*DRAIN SYSTEM

-The drain system ensures the draining of the live steam piping and turbine and prevent the water from entering the

  turbine.

  Each drain line has two branches:

  + manually controlled drain (used during starting period and after shut-down)

  + permanent drain (thermostatic steam traps GESTRA)

    a proper function of this device is essential for turbine safe operaion; therefore it is recommended to clean the

    steam traps at least once a year.

->>By correct function the drain pipes downstream of the traps should be hot.

[FUNCTION]

These traps work on following principle: when starting the turbineor when cold condensate or air enters the trap,

the temperature feelers (bi-metel plates) remain even and operation pressure acting in the opening-direction opens

fully the trap cone.

With increasing condensate temperature approaching the saturation line, the temperature feelers become bent

(deformed), this deformation giving rise to a force which closes the cone and so the trap stops the outflow of steam.

In the closing direction on the cone a leaf spring is acting, the characteristic of which must be conform to the force

from temperature-feelers (closing) and from operation steam pressure (opening)

전공이나 계열이 비슷하면 별로 어렵지 않을수도 있죠. 일반적으로 공대생들이 보기엔 그닥 어렵진 않아보이는걸요?

문법이 어렵다거나 하진 않는데.. 단어는 사전 보면서 하시면 될테고..
