- Smart and solid design ensure reliable operation performance and easy maintenance
TECHNICAL INFORMATION
SYSTEM DESCRIPTION
The main purpose of the inert gas production plant is to produce the required quantity of inert gas with the specified oxygen content. The overall inert gas system consists of a combustion air blower, feeding air to the generator where the production of inert gas takes place. The generator has a design capacity as specified, and is automatically operated. In case the produced inert gas capacity is larger than the demand, the system automatically reduce its production.
The main sub-systems for an IGG are:
- Combustion air blowers
- Combustion chamber/scrubber
- Fuel system
- Control system with valves & instruments
- Deck water seal & P/V breaker
Operation and maintenance
- Graphical LCD operator terminal, all major process parameters displayed on the screen
- Combustion chamber and cooling jacket in high performance austenitic stainless steel (ASTM N08904)
- Easy access to burner and combustion chamber by hinged burner front door (no tools required)
- Easy inspection and easy replacement of scrubber components by entering man hole and removable top plate
- Easy installation
- Data communication between panels
Options
- Multiple LCD operator terminals
- System signals and operation available for ships
- IAS via MODBUS or ETHERNET communication
- Tailor made systems
LCD operator terminal functionality
- Start and Stop IG generator system
- Monitor valve positions and motor running status
- Adjust O2 set-point
- Monitor process and status indication
- Monitor alarm and adjust alarm set-points
- Adjust controller set-points and parameters
