Pin Tube Type Marine Exhaust Gas Boiler – Efficient Heat Recovery for Shipboard Systems
Product Overview
The pin tube type marine exhaust gas boiler is engineered to capture waste heat from ship engine exhaust and convert it into high‑quality steam or hot water for onboard heating, fuel‑water heating, and auxiliary power generation. Designed for the harsh marine environment, the boiler’s compact pin‑tube heat‑exchange core delivers rapid heat transfer while tolerating high‑temperature fluctuations and corrosive gases. Its modular construction allows integration into vessels ranging from coastal ferries to large container ships, meeting the strict space and weight constraints of modern naval architecture.
Built to international marine standards, the unit operates continuously under variable load cycles, delivering reliable performance with minimal maintenance. Whether retrofitting an existing fleet or specifying new builds, the boiler provides a proven solution for reducing fuel consumption and complying with IMO Tier III emission regulations.
Competitive Advantages
- High heat‑transfer efficiency (up to 85 %) thanks to the patented pin‑tube geometry.
- Robust stainless‑steel construction resists corrosion from sulfur‑rich exhaust gases.
- Compact footprint – up to 30 % smaller than conventional shell‑and‑tube boilers.
- Easy access for inspection and cleaning; modular panels reduce downtime.
- Compatible with a wide range of marine diesel and dual‑fuel engines.
- Compliant with ABS, DNV‑GL, and IMO certification requirements.

Application Scenarios
Auxiliary heating on cruise liners: The boiler supplies hot water for galley, laundry, and passenger‑area heating, reducing the load on auxiliary diesel generators.
Fuel‑water heating on bulk carriers: By pre‑heating fuel‑water mixtures, the system improves fuel atomization, leading to lower fuel consumption and emissions.
Steam generation for cargo handling on container ships: Reliable steam pressure supports cargo‑hold ventilation and fire‑suppression systems.
Retrofit projects for older vessels: The compact pin‑tube design fits within limited engine‑room spaces, enabling quick upgrades without major structural modifications.
FAQ
What is the minimum order quantity (MOQ) for a custom‑specification boiler?
Our standard MOQ is one unit, but we recommend a batch of three for optimal tooling cost distribution when multiple vessel types share the same design.
Can the pin tube type marine exhaust gas boiler be adapted to different exhaust gas compositions?
Yes. The heat‑exchange core can be fabricated from 316L stainless steel for typical diesel exhaust or from duplex stainless steel for higher sulfur content, ensuring long‑term corrosion resistance.
What is the typical lead time from order confirmation to delivery?
Standard lead time ranges from 15 to 45 days, depending on the selected material grade and any optional control‑system integrations.
What warranty and after‑sales support are provided?
All units carry a 24‑month or 2000‑hour warranty (whichever occurs first) and include on‑site commissioning assistance, spare‑part logistics, and a dedicated technical helpline.
