Learn about marine centrifugal purifiers working, theory related to their working and about the new ALCAP principal that is used nowadays. Purifiers are one of the most essential machinery on board. Being high precision equipment, it becomes very important to be well versed with the principles of operations. Purifiers are often attributed to cause sleepless nights to 4th engineers. Due to these pieces of equipment, the transfer of heat takes. As per the latest reports, around 3 tons of fuel oil spilled overboard during the bunker operations.
The reason for the spill is still unknown. The preventive […]. Please refer this if you are planning to do this course of HV Switch Gear.
Very explanatory article, which would definitely a guide to all juniors as well a refreshing note for all senior marine engineers. However, how to adjust the throughput reducing the flow for better quality of oil should be explained. But the importance and use of pairing tube and difference between the impeller of Mitsubishi and pairing tube of Alfa laval was missing. Oil paring and water pairing chamber was missed.
In alfalaval purifiers ,opening water and closing water are connected through same pipe from the solenoid water block, how do they function during opening and closing of discharge slide. Hello Srinivas, It is because of the pressure difference of water.
Hello MG Staff, I cannot find your given link regarding pressure difference of water by orifice. Your email address will not be published.

All the time centrifugal force tends to retard the horizontal component of the movement causing the particle to approach the underside of the top disc, velocity reduces as it approaches.
The centrifugal force eventually overcomes the force acting on the particle due to fluid movement and the particle starts to move towards the outer rim.

Depending upon the time for which the bowl is kept open, the process is known as partial or total discharge. This reduces chances of foaming. Image Courtesy : hfoplant. Water from the Hydrophore or in some cases, Header tanks are used.

Alfa Laval Clarifier And Purifier Separator [ALCAP] Course ... - WÃƒÂ¤rtsilÃƒÂ¤
For generations, the van der Plas family fishing business relied on marine gas oil to power its trawlers around the North Sea. Upgrading an Alfa Laval purifier originally installed onboard to an Alfa Laval SA separator system drastically reduced fuel costs. When the Dutch fishing trawler KW Catharina set sail on the North Sea in , it signaled more than a generational shift for the van der Plas family. Shipowner Nico van der Plas Sr. In an effort to offset fuel price increments and maintain earnings, the elder and younger van der Plas agreed in to install an HFO-ready engine and two Alfa Laval purifiers on their new meter fishing trawler.
