Steam turbine for the main feed water pump (MFP) drive is a low power turbine, for which energy power losses and energy efficiency analysis are presented in this paper. The MFP steam turbine analysis has been performed within a wide range of turbine loads. The influence of steam specific entropy increment of the real (polytropic) steam expansion upon the MFP turbine energy power losses and energy efficiency has been investigated. During all the observed loads MFP steam turbine energy power losses were in the range between 346.2 kW and 411.4 kW. The MFP steam turbine energy power losses and energy efficiency were most significantly influenced by the steam specific entropy increment. Change in the steam specific entropy increment is directly proportional to the change in MFP turbine energy power losses, while the change in the steam specific entropy increment is reversely proportional to the MFP turbine energy efficiency change. For the observed turbine loads, the MFP steam turbine energy efficiency was in the range between 46.83% and 51.01%.

Pompa multi tingkat untuk mengatasi kebutuhan fluida cair agar dapat mengalirkan ke tempat yang elevasinya sangat tinggi atau sangat jauh atau mempunyai perbedaan tekanan terhadap sisi masuk dan keluar pompa yang sangat tinggi. Pompa multi tingkat digunakan sebagai pompa pengisi air ketel (Boiler Feed Water Pump) dengan 6 buah/tingkat baling-baling (impeller) dan di hubungkan dengan kopling menggunakan penggerak mula turbin uap yang mempunyai variasi kecepatan 4000 rpm   hingga 6000 rpm. Dengan daya input pompa sebesar 831.050 Watt. Torsi putar untuk putaran 6000 Rpm adalah1323,33 Nm. Ditopang hydrodynamic bearing di kedua ujung poros. Pada penelitian ini diamati frekuensi pribadi pada poros rotor, menentukan modeshape poros rotor (Critical speed map ), respon takseimbang(Unbalance response) pada bearing station. Menggunakan Software-X berupa perhitungan perangkat lunak dinamika rotor dibandingkan dengan software Solidworksmenggunakan metode elemen hingga. Studi dinamika rotor mempunyai kecepatan kritis sebesar 2750 CPM dengan kekakuan bearing 1x106 lbf/inchi pada mode 1. Pada mode no.7 akan terjadi simpangan amplitudo yang besar.

Jurnal ini menjelaskan proses produksi body upper generating drum type CAP.120 T/H. Komponen upper generating drum adalah salah satu komponen pada boiler pipa air yang berfungsi sebagai reservoir campuran air dan uap air, dan juga berfungsi untuk memisahkan uap air dengan air pada proses pembentukan uap superheater. Namun tidak semua boiler pipa air (water tube) yang menggunakan upper generating drum ini. Boiler supercritical beroperasi pada tekanan sangat tinggi di atas tekanan kritis, sehingga tidak dimungkinkan terbentuk gelembung-gelembung uap air, karena itulah boiler supercritical tidak memerlukan upper generating drum untuk memisahkan air dengan uap air. Air feed water yang disupply oleh boiler feed water pump, masuk ke boiler menuju economiser dan selanjutnya masuk ke upper generating drum. Dari upper generating drum, air dipompa oleh pompa sirkulasi boiler menuju ke raiser tube/wall tube untuk dapat mencapai fase uap saturasi. Dari raiser tube air kembali masuk ke upper generating drum. Proses Proses produksi body upper generating drum di PT. Bromo Steel (PT. BOSTO) Indonesia melewati beberapa tahapan yaitu: persiapan material, persiapan marking cutting, proses marking cutting, proses rolling, proses welding, dan terakhir yaitu proses control product (QC) untuk menjamin kualitas pengerjaan.
