Definitions
- a fuel tank unit A fuel tank unit
- the present invention relates to a fuel tank unit for storing liquefied gas fuel and liquid fuel comprising a first fuel tank for liquefied gas fuel and a second fuel tank for liquid fuel according to the preamble of claim 1 .
- Such a fuel tank is particularly advantageous in storing fuels for use in marine vessels and land based power plant provided with a large gas engine where the main fuel is gaseous fuel which is stored as liquefied gas and the pilot fuel is liquid fuel such as light fuel oil or marine diesel oil.
- the fuel tank unit is of elongated form having a length, width, height and longitudinal axis lengthwise the unit, and the second shell has, perpendicular to the longitudinal axis, a circular cross section.
- the unit comprises a fuel conduit extending through the second shell and the third shell and the vacuum insulation to the first tank and that the fuel conduit is enclosed with an insulation.
- the second tank comprises at least two separate compartments, wherein advantageously a first compartment of the second tank has a volume which is 1 - 5% of the volume of the first tank.
- the first compartment is configured to store necessary volume of pilot for to enable a gas mode operation of an internal combustion engine.
- Figures 3 - 8 illustrate cross sectional views ll-ll of the figure 1 according to different embodiments of the invention.
- the space between the first shell 18 and the second shell 20 constitutes a heat insulation for the first fuel tank 14.
- at least two walls of the third shell are arranged only in the vicinity of the second shell i.e. there is a small gap arranged between the shells.
- FIG 4 there is shown an embodiment of the invention where two of the walls of the third shell 22 are connected with each other by a rounded fillet complying with the rounded shape of the vessels deck structure 12 or a hull.
- FIG. 5 there is shown an embodiment of the invention where the third shell 22 is integrated to the vessel's deck and/or hull structure.
- the vessel's deck and/or hull wall forms the third shell 22.
- the third shell 22 encloses only partially the second shell 20.
- the second fuel tank 16 is arranged to the end of the tank unit such that the third shell 22 covers substan- tially only the dome-like end part 20' of the second shell 20.
- the third shell 22 is circular having a diameter less than or equal to the diameter of the second shell 20.
- the heat insulation between the first wall and the second wall is a vacuum insulation configured for insulation of liquefied gas.
- the space may also be filled with expanded perlite particles.
- the heat conductivity of the heat insulation is below 0,0023— .
- the tank unit 10 is configured to supply fuel to a so called dual fuel engine where the liquefied gas is used as the main fuel and the liquid fuel, such as a marine diesel oil or light fuel oil, is used as pilot fuel for igniting the main fuel in a combustion chamber of the engine.
- the first compartment 16.1 is dimensioned to contain the pilot fuel for the engines which consume the liquefied gas as the main fuel.
- the volume of the first compartment 16.1 of the second tank 16 has a volume which is advantageously 1 - 5% of the volume of the first tank 14 and therefore the volumes correspond substantially the ratio of the consumption of the pilot and the main fuel.
