LNG Submerged Combustion Vaporizer for High-Capacity Gasification Systems
The Submerged Combustion Vaporizer (SCV) is a direct-fired LNG vaporization system designed for large-scale and continuous natural gas supply. It is also known as an LNG Submerged Combustion Vaporizer, SCV Vaporizer, or Submerged Combustion Gasifier.
It is widely used in LNG receiving terminals, peak shaving plants, industrial gas supply systems, and city gas distribution networks where high flow capacity, stable operation, and weather-independent performance are required.
What Is a Submerged Combustion Vaporizer?
The SCV system uses natural gas combustion to generate high-temperature flue gas, which is discharged directly into a water bath. The heat is transferred to LNG flowing through submerged stainless steel coil tubes, enabling fast and efficient vaporization.
This direct-contact heating method provides superior thermal efficiency and ensures continuous gas supply under demanding operating conditions.
- High thermal efficiency
- Stable continuous output
- Fast response to load fluctuations
- Reliable performance in extreme climates
- Suitable for high-capacity LNG regasification

Process Description
- Natural gas is burned inside the combustion chamber
- High-temperature flue gas is injected into the water bath
- Strong bubbling and turbulence improve heat transfer efficiency
- LNG flows through submerged coil tubes inside the water bath
- LNG absorbs heat and vaporizes into natural gas
- The regasified natural gas is sent to the downstream pipeline system
This design ensures stable vaporization performance even in low-temperature, humid, or extreme weather environments where ambient air vaporizers may lose efficiency.
Advantages
High Efficiency Regasification
Direct-fired heating delivers fast and stable LNG vaporization with strong heat transfer performance, making SCV one of the most efficient solutions for large-scale LNG gasification systems.
Weather-Independent Operation
Unlike ambient air vaporizers, SCV systems maintain stable performance in cold regions, high humidity environments, and harsh weather conditions without frosting problems.
Compact Skid-Mounted Design
The factory-assembled skid structure reduces onsite construction work, shortens installation time, and lowers total project costs.
Flexible Load Control
The wide operating range supports both base load demand and peak shaving requirements, making the system highly adaptable for different gas consumption scenarios.
High Automation and Safety
The integrated PLC control system supports automatic ignition, temperature monitoring, alarm systems, fault diagnosis, and emergency shutdown functions for safe operation.
