Industrial Oil-Fired Boilers — Engineered Thermal Systems

For capacities from 1.0 to 20 Ton/h with working pressures below 2.5 MPa (25 bar), the horizontal 3-pass WNS fire-tube boiler offers lower capital investment, simpler maintenance, and robust water volume buffering against fluctuating steam loads. For high-demand applications (10 to 50+ Ton/h) or pressures exceeding 2.5 MPa up to 3.82 MPa with superheated steam, the SZS double drum D-type water-tube boiler is required for rapid circulation, superior thermal shock resistance, and membrane water wall safety.

Yes. When configured for HFO or Bunker C fuels, Dabonn includes electric and steam heating tracing manifolds to maintain fuel viscosity at 100°C – 130°C before atomization. Additionally, we engineer the economizers with 09CrCuSb (ND Steel) low-temperature dew-point corrosion-resistant alloys to fully withstand acidic sulfur dioxide condensation during low-load operation.

A standard complete Dabonn scope of supply includes: (1) Factory-mounted European burner (Riello/Weishaupt), (2) Dual multistage centrifugal boiler feedwater pumps (Grundfos/CNP), (3) Spiral finned flue gas economizer/condenser, (4) Automatic ion-exchange water softener, (5) Siemens touch PLC electrical cabinet with flame safety sensors, (6) Dual spring safety relief valves, (7) Blowdown valves, and (8) Interconnecting boiler instrumentation and valves.

All pressure vessels are cleaned, nitrogen-purged, desiccated, and sealed with heavy-duty blind flanges prior to ocean transport. Boilers up to 6 Ton/h fit inside 40ft High Cube or Open Top containers. Larger models (10–50 Ton/h) are secured on heavy equipment flat racks or breakbulk shipping with reinforced lifting lugs, documented with international BV, SGS, or TUV inspection reports prior to port loading.
