ABSTRAK

Pada proses pembangkitan energi listrik suatu unit Pembangkit Listrik Tenaga Uap air pengisi diubah menjadi uap di dalam boiler dan kemudian disalurkan ke dalam turbin uap yang terhubung dengan generator. Uap akan mengisi ruang turbin sehingga jika tidak diberikan penutup seal maka uap akan keluar. Maka diberikan seal dari uap yang berasal dari gland steam regulator. Uap dari gland steam regulator memiliki temperatur tinggi sehingga uap tersebut harus dispray dengan nozzle spray agar temperaturnya menjadi rendah. Terdapat permasalahan pada sistem ini yaitu nozzle akan terjadi penyumbatan dan dapat mengakibatkan kerja spray nozzle tidak maksimum. Untuk membersihkan nozzle ini unit harus dimatikanshut down. Berdasarkan kondisi tersebut maka dibuat modifikasi untuk membersihkan nozzle tanpa harus dilakukan shut down unit sehingga akan membuat efisiensi kerja unit lebih baik. Metode yang digunakan dalam penelitian ini adalah studi kasus dan pemodelan. Dilakukan perhitungan untuk menentukan tekanan yang dibutuhkan untuk sistem. Kemudian direncanakan tanki ejector dan pompa vacuum yang akan digunakan untuk membuang tekanan yang berada di tanki menjadi lebih rendah dari tekanan di jalur pipa. Kemudian pemodelan gambar sistem dilakukan dengan menggunakan software Auto CAD untuk memudahkan penjelasan sistem. Sesuai dengan analisa data dan perhitungan didapatkan besarnya kebutuhan tekanan yang dibutuhkan adalah sebesar 042551 Bar.


ABSTRACT

In the process of generating electrical energy of a unit of Steam Power water filler is converted into steam in the boilers and then piped into the steam turbine connected to a generator. Steam turbine that will fill the space if not given the cover seal then the steam will come out. So given the seal of the steam coming from the gland steam regulator. Steam from the gland steam regulator has a high temperature so the steam must be in the spray with the spray nozzle so that the temperature becomes low. There are problems in this system the nozzle will occur and can lead to blockage of the spray nozzle does not work the maximum. To clean the nozzle of this unit must be turned off shut down. Under these conditions the modifications made to clean the nozzle without having to be shut down the unit so it will make the unit better work efficiency. The method used in this study is a case study and modeling. Performed calculations to determine the pressure required for the system. Then the planned tank ejectors and vacuum pumps that will be used to remove the pressure in the tank becomes lower than the pressure in the pipeline. Then the modeling system image is done using Auto CAD software to facilitate explanation of the system. In accordance with the data analysis and calculations obtained tremendous demand for the required pressure is 0.42551 bar.
