Abstract

Disclosed is a burner for particulate fuel, in particular made of biomass, with a primary tube and a core tube arranged in the primary tube. The primary tube and the core tube form a primary tube gap and the primary tube gap is configured to guide a flow of particulate fuel and gaseous combustion means from an inlet-side end to an outlet-side opening of the primary tube. In order to prevent the drawbacks occurring when using coarse-grain particles, preferably biomass, as a fuel for dust firing, or at least to reduce them without having to accept an increased outlay for equipment and / or additional energy losses, at least one device is provided for centring the flow within the primary tube in the region of the outlet-side end of the primary tube.

Description

BACKGROUND OF THE INVENTION

[0001] 1) Field of the Invention

[0002] The invention relates to a burner for particulate fuel, in particular made of biomass, with a primary tube and a core tube arranged in the primary tube, the primary tube and the core tube forming a primary tube gap and the primary tube gap being configured to guide a flow of particulate fuel and gaseous combustion means from an inlet-side end to an outlet-side opening of the primary tube.

[0003] 2) Description of Prior Art

[0004] Burners for the combustion of particulate fuels, such as, in particular, coal, in a combustion chamber have been known for some time. Dust firing is also referred to in this connection.

[0005] A burner of this type is described, for example, in EP 0 571 704 A2. The burner has a core tube, which has air flowing through it, and has a burner gun for igniting the particulate fuel. Arranged concentrically with respect to the core tube is a primary tube, which, with the core tube, forms an annular gap, whi...
