COMPRESSOR CLEANING SYSTEM

MANUAL COMPRESSOR CLEANING SYSTEM 

يستخدم لازالة الاتربة  الموجوده على ريش الكباس والتى تسبب فى تقليل كفاءة الوحدة الغازيه

        يتكون نظام غسيل الكباس من الاتى:

1-    تنك مياه بسعة 750 لتر يتم ملئ التانك بخليط من الماء ومادة منظفه

2- يتم ضخ الخليط باستخدام طلمبة متعددة المراحل بمحرك تيار متردد, فى مدخل الهواء يوجد نوعين من nozzles لعمل 

inject for water لتنظيف الكباس :

2 jet nozzles(for off line), 20 spray nozzles (for off line and on line)

note that:

- It is recommended to perform off line washing once a week.
 -  the off line should be performed at least once every month,If we can not do it due to load of gas turbine

 - If frequent on line washing shall be carried out,can be 
   (1 / 2 per week) according to the environmental conditions.

  Compressor Cleaning at Operating Speed (ON LINE WASHING)

  - If the gas turbine cannot be shut down for compressor washing,The compressor cleaning can be performed at rated speed and on-load. 

  - Compressor washing is suggested at base load 

 with fully opened IGV.

  - Peak load  is not admissible .

Warning: Never use jet nozzles but only the spray nozzles. 
                Do not open drain valves.

Note: Compressor washing at nominal speed is less 
          effective than the washing procedure at
           washing speed. 
          It could be necessary to repeat the procedure
          several times.

finally:

   -   On Line cleaning (GT on load)

   IGV fully open

   Spray nozzles

          Less deep cleaning (repeat the operation few times)

Compressor Washing at Washing Speed (OFF LINE WASHING)

  -  Off Line Washing is performed in four steps: max 700 dm3

     (dm3 = L ) during washing (water + detergent) max 700 dm3 during each rinsing
    (water only) (to be considered the number of rinsing,

    for instance 1400 dm3 in case of 2 rinsing cycles).  
    The tank capacity is approximately 750 liters 

finally:

- Off line cleaning( GT on Turning Gear):

     Jet nozzles

     Spray nozzles

     Deep Cleaning (Always after a GT extended outage)
