Abstract:
The method according to the invention in its broadest aspect is a method for generating a homogeneous mixture of oxidant(s) and vaporized fuel for a catalytic process in a reactor having a reaction space. In particular it comprises a method for generating a homogeneous mixture of oxidant(s) and vaporized liquid fuel for a catalytic process in a reactor having a reaction space (8; 14), and a catalyst (6), comprising the steps of providing a fuel having a boiling point range; providing one or more oxidants and introducing said oxidants in said reaction space (8; 14); heating the oxidant(s) to a temperature above the boiling point range of the fuel, and introducing the fuel into the oxidant(s) in said reaction space; wherein the reaction space is restricted in size such that the dwelling time of the fuel and oxidant mixture is below the explosion limit of the fuel, is outside the cool flame regime, and is not below 25 ms.
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 said fuel. In particular it relates to a fuel injection system for a catalytic burner (310, 313). It comprises preheating means (308', 309, 315; FT) for preheating the catalytic burner (310, 313) and primary fuel supply means (307) for supplying fuel to the catalytic burner (310, 313). The preheating means (308', 309, 315; FT) and the primary fuel supply means (307) are provided in separate compartments (310, 312), said compartments being connected with each other via a channel (CH).
Abstract:
The invention relates to a burner, comprising a generally cylindrical reactor chamber (1) comprising 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).
