Embodiment Construction

[0042] Refer to the following figure 1 One embodiment of a fuel supply device (hereinafter, may be simply referred to as a "fuel supply device") including a specific gravity monitoring control device according to the present invention will be described. The fuel supply device 12 provided with the specific gravity monitoring control device 11 is as follows: figure 1 As shown, it can add water stored in the water tank 14 to the fuel oil (such as C heavy oil) stored in the fuel tank 13 to make water-emulsion fuel, and supply the water-emulsion fuel to the fuel supply device 12 Connected diesel engine 15.

[0043] Furthermore, the fuel supply device 12 can make the water addition weight ratio Sγ of the water-emulsion fuel actually produced and supplied to the diesel engine 15 coincide with, for example, a preset target water addition weight ratio Tγ, or allow water addition weight ratios Kγ1 to Kγ2. As a result, it is possible to prevent water-emulsion fuel having an unexpected ...

Abstract

Provided is a specific gravity monitoring control device capable of measuring and monitoring the specific gravity of fuel oil actually used when water emulsion fuel is produced by adding water to the fuel oil, and capable of producing the water emulsion fuel with an accurate target additional water weight ratio by adjusting the amount of the water to be added to the fuel oil using the specific gravity of the fuel oil obtained by the measurement. The specific gravity monitoring control device has a configuration in which when fuel oil is emulsified by adding water to the fuel oil, water emulsion fuel with a desired accurate target additional water weight ratio (T) can be produced by measuring the specific gravity of the fuel oil by a first specific gravity measuring unit (21), making a calculation using a first measured specific gravity (go) obtained by the measurement by the first specific gravity measuring unit (21), and adjusting the amount of the water to be added to the fuel oil on the basis of the result of the calculation.

Description

technical field [0001] The present invention relates to measuring the specific gravity of fuel oil actually used when water is added to fuel oil to produce water-emulsion fuel, and using the measured specific gravity of fuel oil to adjust the amount of water added to fuel oil, thereby being able to A specific gravity monitoring and control device for water-emulsion fuel with a desired target water addition weight ratio and a fuel supply device equipped with it are fabricated. 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. Using this water-emulsion fuel as a fuel for an internal combustion engine can reduce NO in exhaust gas X The technology of the composition has been generally recognized and can also be applied to marine diesel engines. [0003] However, the NO in the exhaust based on the use of the water-emulsion fuel X In the reduct...
