Problems solved by technology

[0005] However, in this fuel supply device, when the booster pump breaks down and cannot be driven normally, the supply pressure of the water-emulsion fuel in the supply pipe drops, and the moisture contained in the water-emulsion fuel at a high temperature of 100° C. or higher evaporates simultaneously (flash steam), which may cause a hazard to the supply tube and the equipment connected to the supply tube

Embodiment Construction

[0034] Below, refer to figure 1 A first embodiment of a fuel supply device with a flashing prevention device (hereinafter, may be simply referred to as a "fuel supply device") according to the present invention will be described. Such as figure 1 As shown, the fuel supply device 11 can make the water-emulsion fuel obtained by mixing the first fuel oil stored in the first fuel tank 12 and the water stored in the water tank 13 with the mixer 14 into a state of high temperature and high pressure. And in this state, it circulates in a predetermined circulation line 15 , and the water-emulsion fuel circulated in this circulation line 15 is supplied to a diesel engine 16 connected to this circulation line 15 . And, if figure 1 As shown, with respect to the fuel supply pump P1 that supplies the first fuel oil to the mixer 14 , the flash prevention pump P2 is connected to the circulation line 15 as a backup.

[0035] According to the fuel supply device 11 with this flashing prevent...

Abstract

A fuel supply apparatus (11) with an anti-flashing equipment is configured such that a water-emulsion fuel obtained by mixing first fuel oil and water is able to be circulated in a circulation line (15) and the water-emulsion fuel circulating in the circulation line (15) is able to be supplied to a diesel engine (16) connected to the circulation line (15), wherein: an anti-flashing pump (P2) is connected to the circulation line (15) as a backup of a fuel supply pump (P1) configured to supply the first fuel oil to a mixer (14); the fuel supply pump (P1) is driven by a first electric motor (M1); and the anti-flashing pump (P2) is driven by a second air motor (M2).

Description

technical field [0001] The present invention relates to a fuel supply device equipped with a flashing prevention device for supplying water-emulsion fuel mixed with fuel oil and water to a stationary or mobile diesel engine (engine), especially a ship. Background technique [0002] as NO in the exhaust of internal combustion engines X Cutting technology has a water-emulsion fuel obtained by mixing water with fuel oil and stirring it. Use this water-emulsion fuel as fuel for internal combustion engines to reduce NO in exhaust gas X The technology of the composition is generally recognized and can also be applied to marine diesel engines. [0003] However, in this marine diesel engine, heavy oil C can be used as fuel oil, and when water-emulsion fuel is used, heavy oil C can be used as the base fuel oil. [0004] However, the viscosity of the water-emulsion fuel based on this C heavy oil is very high, and it needs to be heated to 100 degreeC or more in order to lower a visc...
