Fuel heating system of vessel

Abstract

The invention discloses a fuel heating system of a vessel. The fuel heating system comprises an oil bunker, heating coils and a steam system, wherein the two heating coils are arranged inside the oil bunker; the first heating coil is arranged close to a fuel suction hole of a lightering zone of the oil bunker, and is only used for heating fuel in the lightering zone; the second hating coil is arranged in the position outside the lightering zone of the oil bunker; and the steam system is connected with the two heating coils to independently control the two heating coils to operate. Compared with a traditional fuel heating system of the vessel, the fuel heating system of the vessel has the advantages that the preheating speed can be increased, and the energy conservation effect can be improved.

Description

technical field [0001] The invention relates to the technical field of fuel oil heating for ships, in particular to a fuel oil heating system for ships. Background technique [0002] Before transferring the fuel oil in the fuel storage tank, it is necessary to preheat the fuel storage tank to about 50°C a long time in advance (such as 48 hours, depending on the size of the fuel tank, heating capacity and ambient temperature, etc.). The high temperature of the tank will accelerate the corrosion of the bulkhead of the adjacent water tank and the deterioration of the temperature-sensitive cargo in the adjacent cargo tank. [0003] In addition, during the voyage of the ship, the entire oil tank needs to be insulated to ensure that the fuel oil can be transferred at any time. The heat required for heat preservation is all used to balance the heat exchange between the entire oil tank and the outside world. This part of the heat accounts for about 8% to 20% of the heat / steam deman...

AI Technical Summary

Problems solved by technology

[0005] The system is more complicated and expensive, and needs to add two fuel shifter pumps, a heater, a filter, and two restrictor valves and some other valves and control systems

In order to continuously alternately use the shifter pump to transfer the fuel from the clarification tank / daily tank to the fuel storage tank, and then use the fuel transfer pump to transfer the oil from the fuel storage tank to the fuel oil clarification tank; this system needs to increase power consumption;

[0006] Because the system requires mechanical components and control modules to operate, its reliability is not as good as that of the traditional fuel oil storage tank heating coil heating system. Once something goes wrong, the ship will have no fuel available
