Heavy fractions, such as heating oil is very thick and slow and cold so that these oils are loaded and unloaded without delay, it is necessary to heat them. Today the oil business is so big and widespread that the average oil trade is a trip to the tropics and the Arctic conditions be next. And 'therefore necessary that the load of heating systems designed to cope with extreme conditions.
Due to the fact that a loaded tankerrelatively low freeboard, the temperature of sea water passed through the vessel of great importance. Cold water surrounds the hull, deck and the floor quickly reduces the temperature of the load and makes the task much more difficult to heat. Sea water has the opposite effect and can be very useful to maintain the temperature of the charge with a minimum amount of steam. The steam is used to ship the oil inside the reservoir of heat. E 'Direct from the boiler for the entire length of the deck. In general, the runway or flying bridge is used for this purpose.
Exhaust System
The main steam heating load and unload fixed to vertical or horizontal bars takes effect immediately with the work under the foot either. At intervals, is organized varies from individual steam for cargo tanks, it is drawn. Each tank has its own strengths and exhaust valves, allowing the steam to close or reduce to one of the tanksit is not. In general, the main steam lines are well behind, but obviously it is not practical, the individual lines remain the distributor of the cargo.
The heaters in the existing cargo tanks are made of a system of coils that are on the bottom of the tank at a distance of 6-18 cm from the primer distributed. In wing tanks, it is usual to go for the coil system, which in turn in the bilge, but not the hull.
