The Combustion Vaporizer is a large-scale industrial solution for LNG and cryogenic fluid vaporization, utilizing direct or indirect combustion to generate thermal energy. Available in two primary configurations—Submerged Combustion Vaporizers (SCV) and Open Rack Vaporizers (ORV)—these systems deliver vaporization rates up to 200,000 Nm³/h with 97% thermal efficiency, making them indispensable for LNG terminals and peak shaving facilities .
Submerged Combustion Vaporizer (SCV):
Natural gas or boil-off gas (BOG) is burned in submerged burners, producing exhaust gases (800–1,000°C) that bubble through a water bath. LNG flows through coils submerged in the bath, absorbing heat to vaporize.
Low-NOx burners (e.g., Siemens ELCO) limit nitrogen oxide emissions to ≤30 ppm, with optional SCR systems reducing levels to ≤5 ppm for strict regulatory zones .
Open Rack Vaporizer (ORV):
Ambient air or seawater flows over finned aluminum tubes, transferring heat to LNG inside. Ideal for coastal terminals, ORVs operate with zero emissions and minimal energy input.
Air preheating systems (gas-fired heaters) prevent frost buildup on fins, ensuring frost-free operation even at -10°C ambient temperatures .
Ultra-High Capacity and Efficiency
Modular design allows incremental expansion (e.g., adding 50,000 Nm³/h burner modules to scale from 50,000 to 200,000 Nm³/h), accommodating growing facility demands.
Water bath thermal buffering in SCVs stabilizes output during load fluctuations (±20% of setpoint), preventing pressure spikes in downstream pipelines .
Low-Emission and Safe Operation
SCVs equipped with selective catalytic reduction (SCR) systems use urea injection to convert NOx to nitrogen and water, meeting EU Industrial Emissions Directive limits.
Dual-leak detection systems (infrared hydrocarbon sensors and differential pressure monitors) trigger shutdown within 10 seconds of LNG or fuel gas leaks, with emergency isolation valves stopping flow .
Durable Construction
9% nickel steel coils (for LNG contact) resist embrittlement at -162°C, while 316L stainless steel casings in ORVs withstand saltwater corrosion in marine environments.
Self-cleaning burners (John Zink Hamworthy designs) use compressed air to remove carbon deposits, reducing maintenance frequency by 50% compared to conventional burners .
LNG Import Terminals: 150,000–200,000 Nm³/h SCVs serve as primary vaporizers, converting LNG from storage tanks to pipeline gas (20–70 bar) for distribution.
Peak Shaving Stations: 100,000 Nm³/h SCVs activate during winter demand spikes, increasing gas supply to grids within 15 minutes of startup.
Aerospace Propulsion: 50,000 Nm³/h ORVs with NASA-approved materials vaporize liquid hydrogen (LH₂) for rocket fuel, maintaining -253°C storage to 20 bar gaseous output.
Q: What fuels can Combustion Vaporizers use?
A: They are compatible with natural gas (methane), LNG boil-off gas (BOG), propane, or diesel, with automatic fuel switching (via PLC control) ensuring uninterrupted operation if primary fuel supply fails .
Q: How does SCV compare to ORV in terms of water consumption?
A: SCVs consume 5–10 m³/h of makeup water to replace evaporation losses in the bath, while ORVs use 100–200 m³/h of seawater (or ambient air) for heat exchange, with no water consumption in air-cooled models .
Q: What is the typical lifespan of SCV components?
A: Burner nozzles require replacement every 1–2 years (depending on fuel quality), while heat exchanger coils (9% nickel steel) have a 15–20 year lifespan under normal operating conditions (≤8,000 hours/year) .
