An oil recovery system

A hermetically sealed lubrication oil circulation system comprising:

• a lubrication oil dispenser system that is configured to provide lubrication oil to a bearing;
• a container defining a holding space for holding contaminated lubrication oil that has come out of the bearing;
• an oil recovery system comprising:
• a container defining a holding space for holding oil, wherein the holding space comprises an upper region and comprises a lower region for receiving solid contaminants that have sunk through the oil in the holding space.
• a heating system that is configured to heat oil in the upper region to a greater extent than oil in the lower region, wherein the heating system is configured to cause oil in the upper region to evaporate, and
• a condenser system that is configured to condense the evaporated oil and guide the condensed oil out of the container,
• wherein the oil recovery system is configured to boil the contaminated lubrication oil in order to evaporate clean lubrication oil and condense the clean, evaporated lubrication oil;
• and
• a transport system that is configured to transport the clean, condensed lubrication oil to the lubrication oil dispenser system so that the lubrication oil dispenser system can provide the clean lubrication oil to the bearing.

A computer-implemented method for controlling a heating system of an oil recovery system, the oil recovery system comprising:

• a container defining a holding space for holding oil, wherein the holding space comprises an upper region and comprises a lower region for receiving solid contaminants that have sunk through the oil in the holding space.
• the heating system that is configured to heat oil in the upper region to a greater extent than oil in the lower region, wherein the heating system is configured to cause oil in the upper region to evaporate, and
• a condenser system that is configured to condense the evaporated oil and guide the condensed oil out of the container, the method comprising:
• receiving from an or the oil level measurement system a signal indicative of an amount of oil in the holding space;
• and
• based on the indicated amount of oil in the holding space, causing the heating system to heat the oil in the holding space herewith causing at least some of the oil in the holding space to evaporate.
