  • Patent number: 9964302
    Abstract: The present invention relates to a system for utilizing liquid fuels, such as diesel and gasoline, in a catalytic reactor for producing clean heat from the fuel. In particular it relates to a fuel injection system for a catalytic burner (310, 313). It includes preheating elements (308?, 309, 315; FT) for preheating the catalytic burner (310, 313) and primary fuel supply elements (307) for supplying fuel to the catalytic burner (310, 313). The preheating elements (308?, 309, 315; FT) and the primary fuel supply elements (307) are provided in separate compartments (310, 312), the compartments being connected with each other via a channel (CH).

  • Patent number: 9857075
    Abstract: A combustor for providing homogeneous combustion of liquid fuels includes an essentially tube shaped combustion body, including a combustion chamber having a plurality of reaction zones, one of which is an injection zone, the others being combustion zones for staged homogeneous combustion of evaporated fuel and air. A swirler, including a base and swirler elements, is configured to operate at a swirl number between 0.6-2.5 in combination with a flow constriction plate whose size is such that the ratio of the open diameter (De) of the constriction to the diameter (D) of the combustion body is <0.7 and the constrictor plate is placed at a distance (L1) from the base of the swirler base so that L1/De>1. A primary mixing plate is placed downstream from the constriction plate at a distance (L2) so that the ratio L2/L1<1 to allow maximum mixing of the homogeneous combustion.

  • Patent number: 9618198
    Abstract: A burner includes a generally cylindrical reactor chamber (1) including a housing (1?) having a proximal end (1p) and a distal end (1d). In the distal end of the reactor chamber (1) there is provided a catalyst (4). A fuel inlet (7) is provided in the proximal end of the reactor chamber. There are also a plurality of air inlets (22, 23; 24) arranged in the reactor wall at the proximal end. The inlets are configured to provide a rotating flow of the air injected into the reactor chamber. There is also provided a flow homogenizer (8; 30) extending over the cross-section of the reactor chamber at a position between the fuel inlet (7) and the catalyst (4).

  • Patent number: 8641789
    Abstract: A reformer reactor is provided for converting hydrocarbon fuel into hydrogen rich gas by auto-thermal reaction process. The reformer reactor has a preferably cylindrically shaped, double wall housing with an inner wall and an outer wall and two side faces, wherein the inner wall and the two side faces form a reaction chamber. Additionally, the inner wall is charged with a first electric charge which prevents the hydrocarbon fuel molecules injected into the reaction chamber by a fuel inlet from hitting the warm inside surfaces of the reaction chamber and burn to soot, subsequently.
