A marine ethanol fuel supply system and its operation control method
By setting up first and second heat exchangers for heat exchange in the marine ethanol fuel supply system, and combining them with electrical control units and sensors, the problems of low heat exchange efficiency and poor temperature stability are solved. This enables precise control of fuel temperature and reduction of residue, improves the system's intelligence level and applicability, and makes it suitable for the storage, transportation and heat exchange of marine ethanol fuel.

Abstract
This invention provides a marine ethanol fuel supply system and its operation control method. The supply system includes at least a first heat exchanger and a second heat exchanger. The first heat exchanger contains a first and a second flow channel that are not interconnected. The inlet of the first flow channel is connected to an ethanol storage tank, and its outlet is connected to an ethanol consumption unit. The inlet of the second flow channel is connected to the second heat exchanger, and its outlet is connected to a water-glycol solution expansion tank. The second heat exchanger contains a third and a fourth flow channel that are not interconnected. The inlet of the third flow channel is connected to the water-glycol solution expansion tank, and its outlet is connected to the first heat exchanger. The inlet of the fourth flow channel is connected to a water source inlet, and its outlet is connected to a water source outlet. This allows the low-temperature ethanol fuel to utilize some of the heat from the water. The water-glycol solution and the incoming water exchange heat in the second heat exchanger, compensating for the heat lost by the water-glycol solution in the first heat exchanger, thus ensuring the required temperature of the ethanol fuel in the supply system.
