Chemical Tanker Cargo Tank Washing Marine Boiler – Reliable Steam for Spot‑Cleaning Operations
The chemical tanker cargo tank washing marine boiler is a purpose‑built, compact steam generator designed to supply high‑quality saturated steam for cargo‑tank cleaning on chemical carriers. Engineered to meet the rigorous demands of marine environments, this boiler delivers rapid heat‑up, precise temperature control, and a robust safety envelope, enabling crew to execute wash‑down cycles in compliance with IMO and classification society regulations.
Why This Boiler Stands Out
- Optimised duty cycle: Designed for intermittent operation (up to 6 hours per wash) with fast‑fire capability—full steam pressure reached within 10 minutes.
- Corrosion‑resistant construction: All heat‑exchange surfaces are fabricated from marine‑grade stainless steel (AISI 316L) and coated with a proprietary anti‑scale treatment.
- Energy‑efficient combustion: Low‑NOx burner meets IMO Tier III emissions, reducing fuel consumption by up to 12 % versus legacy units.
- Compact footprint: 1.2 m × 0.9 m × 1.5 m (L × W × H) – fits in tight engine‑room spaces without sacrificing output.
- Integrated safety suite: Automatic pressure relief, flame‑failure detection, and remote‑shutdown capability aligned with ABS, DNV‑GL, and Lloyd’s Register standards.
Technical Profile – Typical Specifications (customizable per order)
| Parameter | Standard Range | Optional Upgrade |
|---|---|---|
| Steam pressure (gauge) | 5–7 bar | 8–10 bar (high‑pressure option) |
| Steam flow rate | 350–500 kg/h | 600 kg/h (enhanced burner) |
| Fuel type | Marine diesel, heavy fuel oil | Dual‑fuel (diesel/LNG) |
| Electrical supply | 380 V / 50 Hz | 230 V / 60 Hz (export markets) |
| Control system | PLC with HMI (touch screen) | SCADA integration |
| Weight (incl. accessories) | 2 800 kg | 3 200 kg (with reinforced frame) |
All dimensions, pressure ratings, and control options can be adapted to the vessel’s layout and the shipowner’s operational policies.
Typical Application Scenarios
The boiler is most commonly installed on chemical tankers that transport corrosive bulk liquids such as acids, solvents, and specialty polymers. Its rapid steam generation supports the following critical tasks:
- Pre‑cargo cleaning: Achieve ISO‑based cleanliness levels (e.g., ISO 20843‑1) before loading a new cargo batch.
- Post‑cargo residue removal: Dissolve stubborn deposits using high‑temperature steam combined with compatible cleaning agents.
- Tank inspection preparation: Provide consistent heat to dry and de‑humidify tanks ahead of non‑destructive testing.
- Emergency de‑contamination: Enable rapid response to accidental spills, minimizing downtime and regulatory penalties.
Because the unit operates independently of the main propulsion plant, it can be run while the ship is in port or at anchor, giving operators full flexibility to meet tight turnaround schedules.
Industry Certifications & Safety Compliance
Our marine boiler conforms to the principal classification society rules (ABS, DNV‑GL, LR) and carries the following certifications:
- ISO 9001:2015 quality management system.
- ISO 14001 environmental management – low‑emission burner.
- IMO MARPOL Annex VI Tier III NOx compliance.
- ASME Section III, Division 1 – Power Boilers.
- CE marking for equipment used in European waters.
All safety devices are tested in accordance with IEC 61508 functional safety standards, ensuring automatic shutdown in case of over‑pressure, flame‑out, or electrical fault.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑spec boiler?
We accept single‑unit orders for new‑build projects and retrofits. Volume discounts apply from a batch of five units onward.
Can the boiler be adapted for dual‑fuel (diesel/LNG) operation?
Yes. The optional dual‑fuel package includes a certified LNG burner, fuel‑line segregation, and the necessary control‑system firmware. Lead time for this configuration is an additional 10 days.
What is the typical delivery lead time after order confirmation?
Standard models ship within 25–35 days. Custom‑specifications (e.g., high‑pressure, SCADA integration) require 45–60 days, depending on engineering workload.
What warranty and after‑sales support are provided for the chemical tanker cargo tank washing marine boiler?
All units carry a 24‑month manufacturer’s warranty covering material and workmanship. We also offer optional extended service contracts that include on‑site commissioning, spare‑parts stocking, and 24 h technical hot‑line support.
