Application Fuel conditioning is the term given to a system that treats the heavy oil used as fuel in marine diesels and diesel power stations so that it meets the requirements for cleanliness, pressure, temperature, viscosity and flow rate specified by the engine manufacturer. If these requirements are not met, then this will result in inferior performance of the engine and can result in increased emissions due to poor combustion. Various configurations of fuel conditioning systems have been used but experience has shown that the so-called two stage pressurized systems are to be preferred. Single stage systems can be difficult to control and tend to suffer from the cavitation and gasification problems associated with high fuel temperatures. A major requirement of a fuel conditioning system is that it can easily be configured to meet the requirements of a specific engine or engine room layout. The Alfa Laval Fuel Conditioning Module Carefully engineered taking into consideration the lessons learnt from previous, and existing, fuel conditioning systems, the new Alfa Laval Fuel Conditioning Modules are very compact, simple to install and have what is possibly the best control system available on the market. The complete FCM consists of carefully selected main components mounted on a frame, complete with piping, valves, and electrical cabling and other accessories. A centrally placed cabinet contains the starters for all motors and the advanced process controller with self-cure functions and manual backup possibilities. Based on a standardized concept, the pressurized booster systems can easily be configured to meet the specific requirements of any engine and engine room layout. Maximum consideration has been given to good access to all components, and to the control system that provides truly “start and forget” operation. Fuel Conditioning Module.

System description The Alfa Laval Fuel Conditioning Module is a two stage pressurized booster system that uses viscosity as the primary control parameter. Pressure in the low-pressure section is maintained at 4 bar whilst the pressure in the high-pressure section will be within the range 6 to 16 bar depending upon the requirements of the engine manufacturer. Low pressure stage The low pressure stage includes two supply pumps (one in operation, one on standby), an Alfa Laval automatic filter with a manual bypass filter as back up, and a flow transmitter to provide information on fuel consumption....

high fuel temperatures (120–150°C). This will ensure an even fuel flow and prevent damage to the pumps. Oil filters An Alfa Laval automatic back flush main filter backed up by a manual by-pass filter removes any particles present in the fuel that could cause engine damage. Continuous automatic back flushing and robust disc type filter elements guarantee high efficiency and minimum maintenance requirement. As an alternative, the filtration stage can be moved over to the high-pressure stage but because of the higher flow rates this normally will require a larger filter for a given engine. Flow...
