2. Organization of repair of the equipment, buildings and constructions of power plants

12. The perspective plan and the annual schedule of repair of the power making organizations are developed taking into account working capacity of the relevant power plant.

13. In case of schedule development of repair of the equipment of the power making organizations it is necessary to consider the following:

Total 1) equipment downtime duration in all types of repair is established taking into account the approved worker of capacity of the relevant power plant;

2) capital repairs of head installations are planned in the terms determined taking into account their technical condition and requirements of manufacturing plant;

3) the hydroaggregates put into operation in case of pressures which size is lower settlement (minimum) ranging from fifteen to twenty percent is recommended to be removed in capital repairs in two years after installation;

4) repair of the body of coppers the double blocks is planned with simultaneous stop and launch of both body or shift of stop and start-up of one of the body determined by technology of repair and service conditions;

5) terms of repair of package boilers at power plants with cross communications is going to be combined with terms of repairs of turbine units;

6) capital repairs of the reserve service equipment are planned during the periods between capital repairs of the capital equipment;

7) capital repairs of the all-station equipment which shutdown does not limit working power of the power plants, are planned for the periods between repairs of the capital equipment;

8) the capital repairs of the all-station equipment connected with decrease in working power of the power plant are planned along with repair of the capital equipment.

14. In need of the conclusion of chimneys, gas flues and coolers in repair for long term connected with capacity limitation of power plant, the power making organizations provide switching of the capital equipment to other constructions or installation for repair of the shoddy constructions which are reducing or completely eliminating capacity limitation.

15. Conclusion in repair of the equipment of the power making organization is made according to the program approved by the power making organization which shall provide:

1) carrying out operating tests. Testing shall be carried out not earlier than before month and not later than five days to equipment conclusion to repair. Results of testing are entered in sheets of key parameters of technical condition of installation according to appendices 4 - 11 to these rules;

2) cleaning of installation outside of (platforms of servicing, the outside surface of the equipment, pipelines, gazo-and air ducts, dust flues within installation) from dust, ashes and garbage, removal from workplaces of the foreign equipment, materials which is made after equipment stop;

3) drawdown of fuel in copper bunkers in case of its stop, blowing of surfaces of heating, stryakhivaniye of electrodes of electric precipitators and washing of grit arresters. Ashes and slag from bunkers and letok are removed on ash dump.

4) forced cooling of turbines in case of stop and if necessary washing of flowing part under loading.
