Steam Atomizing Burner for Marine Auxiliary Boiler
Our steam atomizing burner for marine auxiliary boiler delivers reliable, low‑emission heat generation for shipboard steam systems. Engineered for the harsh marine environment, it combines precise fuel control with robust construction to meet the demanding duty cycles of ocean‑going vessels. Whether you are retrofitting an existing plant or specifying a new installation, this burner provides the flexibility and efficiency required by modern maritime operators.
How It Works – Steam Atomization Principle
The unit utilizes a high‑velocity steam jet to atomize liquid fuel into a fine mist. This steam‑fuel mixture is then ignited within the combustion chamber, producing a uniform flame that maximizes heat transfer to the boiler water tubes. Because the atomizing steam is sourced directly from the boiler’s own feed water, the system eliminates the need for external air‑blast equipment, reducing both capital cost and maintenance overhead.
Key operational steps include:
- Steam generation from the auxiliary boiler’s feed pump.
- Metered delivery of fuel to the atomizing nozzle.
- High‑pressure steam shears the fuel into droplets (≤30 µm).
- Flame stabilization via staged air ports for optimal NOx control.
- Heat absorption by the boiler water walls and return to the steam cycle.
Application Scenarios
This burner is purpose‑built for a range of marine applications where space, weight, and emissions are critical considerations:
- Auxiliary steam generation on cargo ships, tankers, and cruise liners for heating, fuel‑oil pre‑heat, and deck‑wash systems.
- Hybrid propulsion support where auxiliary steam supplements LNG or diesel engines during low‑load periods.
- Retrofit projects on older vessels seeking to meet IMO Tier III NOx limits without extensive redesign.
- Offshore platforms where compact, low‑vibration burners are required for process steam.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑spec steam atomizing burner?
We accept single‑unit orders for prototype or trial installations. For series production, the typical MOQ is 5 units, which allows us to optimize tooling and logistics while keeping lead times competitive.
Can the burner be adapted to use alternative fuels such as bio‑diesel?
Yes. Our design supports a range of liquid fuels. Upon request we can provide material upgrades (e.g., corrosion‑resistant alloys) and calibrate the control system for the specific calorific value of bio‑diesel or blends up to 30 % renewable content.
What is the typical lead time from order to shipment?
Standard configurations ship within 15–30 days after order confirmation. Fully customized solutions, including special material selections or control‑system integration, require 30–45 days depending on the complexity of the request.
How is warranty support handled for vessels operating in remote regions?
Our 12‑month/2,000‑hour warranty includes on‑site technical assistance through a global network of authorized service partners. For remote deployments, we can arrange spare‑part kits and remote diagnostics to minimize downtime.
