steam blow PLTU Teluk Sirih

Steam Blow Steam blow wajib dilakukan sebelum pengoperasian unit pembangkit listrik tenaga uap. Steam blow adalah proses pembersihan pemipaan pada siklus uap dengan menggunakan energi kinetik dari uap yang dihasilkan pemompaanboiler feed pump (BFP) dan pembakaran di bolier. Tujuan dari proses steam blow adalah membersihkan semua partikel sisa seperti pasir, batu, partikel besi dan metal lain, slag pengelasan, dan juga scaling pada permukaan dalam pipa yang tertinggal di superheater dan pipa uap lainnya selama pembuatan pembangkit. Steam Blow yang dilakukan dibagi menjadi tiga tahap yaitu : 1. Tahap pertama main steam system Steam Blow Jalur uap melalui : drum → superheater → main steam pipe → boiler main steam valve → main steam pipe → temporary blow steam control valve → temporary exhaust steam pipe. 2. Tahap kedua desuperheater water piping system steam blow (temporary pipe disambung setelah desuperheater water pipe motor driven valve) Jalur uap melalui : drum → superheater → desuperheater pipe → temporary pipe 3. Tahap ketiga pipa turbine bypass system Jalur uap : drum → main steam pipe → main steam bypass pipe → temporary exhaust steam pipe. Tekanan pada Steam drum ketika steam blow (dalam MPa) Berikut Data - Data Steam Blowing Pada PLTU Teluk Sirih  STEAM BLOWING  BOILER   #1
