MARITIME PROTECTION FLEXINERT GAS GENERATOR
The Flex Inert Gas Generator system is a combination of a flue gas system and an inert gas generator. It creates inert gas out of the burning processes. The gas contains less than 5% oxygen and ensures a non-explosive atmosphere in the cargo tanks and their piping arrangement. As long as sufficient boiler flue gas is available, the inert gas generator is by-passed and the system works as a flue gas system. When no basis gas is available, it works as an inert gas generator
KEY FEATURES
TECHNICAL INFORMATION
SYSTEM DESCRIPTION AND CONFIGURATION
The main purpose of the Flexinert gas production plant is to produce the required quantity of inert gas with the specified oxygen content. As long as sufficient boiler flue gas is available, the inert gas generator is by-passed and the system works as a flue gas system. When no basis gas is available, it works as an inert gas generator.
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:
Operation and maintenance
Options
LCD operator terminal functionality
System configuration with compact cooler and rotating adsorption dryer
Rotating adsorption dryer
Utilizing the more maintenance friendly centrifugal blowers
Closed loop cooling system provided through a glycol/water circuit from a separate water chiller unit
SYSTEM APPLICATIONS
Flexinert gas systems are commonly used on tankers with large boilers for inerting of cargo tanks, cargo piping and machinery and purging of tanks.
