Definitions

  • the invention relates to the fuel system of a large vessel running on heavy fuel oil. More specifically it relates to a system for extracting heated heavy fuel oil from an elongated storage tank with low height.
  • EP2630402 B1 describes a storage tank for heavy fuel oil or other high viscous fluids which is equipped with a convection shield with heating elements inside enabling pumping from the tank without having to heat the complete tank according to patent.
  • the object of the invention is to solve the mentioned problems and supply a reliable flow of fuel also during cold conditions.
  • the invention describes a system for extraction of heated heavy fuel oil from an elongated heavy fuel oil storage tank.
  • the system comprises a convection shield with closed top and side and a substantially open bottom, wherein the convection shield is mounted with a clearance between the bottom of the storage tank and the lower edge of the convection shield to allow for entry of heavy fuel oil into the convection shield through the open bottom,
  • the system further comprises a heating element arranged inside the convection shield for heating the heavy fuel oil inside the convection shield and a fuel suction line arranged inside the convection shield for extracting heated heavy fuel oil from the heavy fuel oil storage tank.
  • the system further comprises an elongated inflow convection shield, which in turn comprises a closed upper part comprising a top and sides, a lower part, with openings for throughflow, positioned at the same height or lower as the lower edge of the convection shield to allow entry of heavy fuel oil into the inflow convection shield through the lower part.
  • the inflow convection shield is connected to the lower edge of the convection shield, sharing a common interior allowing unhindered flow of heated heavy fuel oil from the inflow convection shield to the convection shield.
  • An inflow heating element is positioned along the length of and inside the inflow convection shield for heating the heavy fuel oil inside the inflow convection shield, and the inflow convection shield extends along the bottom of the storage tank in its longitudinal direction.
  • the inflow heating element is a heating pipe running inside the inflow convection shield in a loop out from the convection shield (2) to the end piece and back again.
  • the inflow convection shield has the shape of an elongated rectangular volume with a top, two sides and an end piece at the outer end of the inflow convection shield and a bottom with a plurality of openings.
  • the inflow convection shield extends along more than 10 % of the length or width of the storage tank, preferably more than 30 % of the length of the storage tank.
  • the convection shield has a bulk heating valve mounted at the top of the convection shield.
  • the system is provided with a second stage heater downstream of the convection shield, wherein the second stage heater comprises a second stage convection shield with a closed top and sides and a mainly closed bottom, a second stage heating element positioned inside the second stage convection shield, a second stage channel leading partially heated heavy fuel oil from the top of the second stage convection shield to the bottom of the second stage heater and a fuel suction line positioned inside the inflow convection shield.
  • a fuel suction line is positioned inside the second stage convection shield near the top.
  • the second stage convection shield has a bulk heating valve mounted at the top of the convection shield.
  • the second stage convection shield has drain holes in the bottom of the second stage convection shield.
  • Fig. 1 shows a convection shield having an inflow convection shield mounted.
  • Fig. 2 shows a heavy fuel oil fuel tank with convection shield having a inflow convection shield mounted.
  • Fig. 3 shows a cross section of an embodiment of an inflow convection shield mounted.
  • Fig. 4 shows the embodiment from fig. 2 with a second stage heater mounted and a typical flow pattern of heavy fuel oil through an active system.
  • Fig. 5 shows a flow pattern in a storage tank using an embodiment of the invention with an open bulk heater valve.
  • the system as seen in fig. 1 and 2, comprises a convection shield 2 having a closed top 8 and closed sides 9 and a mainly open bottom side.
  • the convection shield 2 is box shaped, or alternatively has the shape of an upside-down bucket or a hollow cylinder with a circular top.
  • a heating element 3 is positioned inside the convection shield 2 and a convection flow 6 emerges when the heating element is heating the heavy fuel oil.
  • An exemplary flow pattern is seen in figure 2.
  • the heated heavy fuel is extracted from inside of the convection shield 2 by means of a fuel suction line 4.
  • the intake of the fuel suction line 4 is positioned in the upper end of the convection shield near the top where the temperature of the heavy fuel oil is high.
  • the convection shield 2 is mounted near the bottom of the storage tank f, but with a clearance between the bottom of the storage tank f and the lower edge of the convection shield to allow for entry of heavy fuel oil into the convection shield 2 through the open bottom.
  • the clearance between the lower edge of the convection shield and the bottom of the storage tank is between 5 and 70 cm, more preferably between f0 and f5 cm.
  • the invention describes an elongated inflow convection shield 10 with a closed upper part f f comprising a top 12 and sides 13 and an end piece 14 at the outer end of the inflow convection shield 10.
  • the inflow convection shield further comprises a lower part 16 with openings 17 and is mounted at the same height, or lower, as the lower edge of the convection shield to allow entry of heavy fuel oil into the convection shield through the openings in the lower part bottom.
  • the inflow convection shield 10 has the shape of an elongated rectangular volume with an open bottom. The inflow convection shield is connected to the lower edge of the convection shield.
  • an opening matching the cross-section of the inflow convection shield is cut into the lower side of the convection shield where the inflow convection shield is fastened, to allow unhindered flow of partially heated heavy fuel oil from the inflow convection shield 10 into the convection shield 2 for further heating.
  • the convection shield and inflow convection shield are sharing a common interior allowing unhindered flow of heated heavy fuel oil from the inflow convection shield to the convection shield.
  • a second stage heater 21 is connected downstream of the convection shield.
  • the purpose of the second stage heater is to provide a more stable temperature because the low height of the convection shield, and consequently also the low height of the heating element 3, results in larger variations in the temperature of the heavy fuel oil entering the fuel suction line 4, which may result in the suction line clogging up.
  • the second stage heater 21 comprises a second stage convection shield 19 with a closed top 9 and sides 8, a mainly closed bottom 24 and a second stage heating element 20.
  • the bottom 24 of the secondary convection shield must be mainly closed in order to create a suction of heated heavy oil from the convection shield 2 to the secondary convection shield 19 because of the secondary fuel suction pipe 23 extracting heavy fuel oil from the secondary convection shield.
  • the bottom 24 has drain holes.
  • a second stage channel 22 leads partly heated heavy fuel oil from the top of the convection shield to the bottom of the second stage heater 21.
  • a second stage fuel suction line 23 is positioned inside the second stage convection shield 19. Inventory
