TECHNICAL PROPOSAL
Boiler
Combined water tube – fire tube steam boiler , consist of ;
- Forced draft combustion air fan
- Water tube pre-furnace combustion chamber
- Fire Tube Boiler convection drum
- Multi-Cyclone De-duster Unit Flue gas
- ID fan (Flue Gas Fan)
- Chimney 15 m
- Fuel Hopper and Silo (Fuel Feeding) with Bucket elevator
Spesifikasi dan karakteristik
Pembakaran yang optimal dan perpindahan panas maksimum dengan system tungku basah, dengan ruang yang luas, pembakaran tidak kontak dengan dinding dingin tungku . Pemanasan permukaan tungku besar menyempurnakan transfer panas yang maksimal. Akibatnya suhu gas buang sudah berkurang jauh,sebelum memasuki tabung api. Konsep ini tidak hanya mengurangi beban pada pelat tabung (yang menjamin kekuatan jangka panjang) danjuga menghindari abu meleleh menempel pada tabung api
Perawatan mudah & aksesibilitas
Pembakaran yang optimal dan dipilih dengan cermat kecepatan gas buang di tabung api mengurangi kekotoran tabung api untuk minimum. Aksesibilitas terjamin melalui pintu.
konstruksi yang solid
Tabung api digulung dan dilas yang menghasilkan:
- kontak erat antara firetube dan piring tabung, untuk menghindari celah adanya korosi outsticking tabung-ujung pada pelat tabung, sehingga pendinginan lengkap terjamin
- tidak ada kekotoran didalam antara tabung pembakaran dan piring tabung Kontrol kualitas fabrikasi:
