Marine Smoke Box | Boiler Flue Gas Collector

Technical Specifications：

Key Features：

• Efficient Exhaust Gas Channeling: Provides a sealed, centralized path for exhaust gas from the boiler outlet to the funnel inlet.
• Enhanced Chimney Draft: An optimized internal design can improve the natural draft effect of the chimney. Better draft promotes more stable combustion.
• Boiler Backflow Protection: Its structure prevents exhaust gas from flowing back into the boiler when not firing. This action reduces corrosion on boiler tubes and shells.
• Precision Fabrication: We build each smoke box with precise dimensions and a stable structure. This ensures a perfect fit and a long service life.

Applications：

• Oil-Fired Boiler Systems: Collects and directs exhaust gases from marine auxiliary and main oil-fired boilers.
• Exhaust Gas Boiler (Economizer) Systems: Serves as the outlet manifold for exhaust gas boilers, channeling the processed gas to the funnel.
• Combined Boiler Systems: Functions as a common collection point for systems with both oil-fired and exhaust gas boilers.

Installation & Maintenance：

Installation: The smoke box is installed between the boiler flue gas outlet and the funnel inlet. Flanged connections must be sealed with            high-temperature gaskets. All supports must be securely fastened to the ship’s structure.
Maintenance: Periodically inspect all welds and seams for cracks or corrosion. Clean internal soot and deposits according to the boiler’s maintenance schedule. Check sensor functionality if sensors are installed.

Custom Options Available：

Need something specific?

We manufacture smoke boxes to fit any boiler model and ship layout. You can specify materials like stainless steel for higher corrosion resistance. We also customize flange standards and the quantity and location of sensor ports.

FAQ ：

Q: What is the main purpose of a smoke box?

A: Its main purpose is to create a safe, sealed path to guide hot exhaust gases from the boiler directly into the ship’s funnel.

Q: How does it protect the boiler?

A: It prevents corrosive exhaust gases from flowing back into the boiler, especially when the boiler is not firing. This action reduces internal corrosion and helps extend the boiler’s service life.

Q: Can a smoke box improve boiler efficiency?

A: An optimized smoke box design can improve the chimney’s natural draft. Better draft can lead to more stable combustion inside the boiler, which contributes to overall efficiency.
