Problems solved by technology

Furthermore, suspended particles and cooling water can over time lead to a narrowing of the cooling water channel in the region of the burner nozzle tip or even to a blockage of the cooling water channel, which entails increased maintenance requirements in order to be able to detect this in good time. kind of narrowing
[0006] In addition, the materials used to produce the burner tip are expensive and the machining is complex, since the components for forming the burner tip have to be welded together

Embodiment Construction

[0034] Refer below figure 1 The principle configuration of a burner for a synthesis gas reactor is described.

[0035] The burner is designed rotationally symmetrically about a burner axis A and comprises a tubular introduction section and a burner nozzle tip 1 connected to the introduction section, which surrounds a burner opening 3 .

[0036] The burner comprises an outer first burner element 2 , which is formed in a tubular section of the burner from three collapsed tubes 4 , 6 , 8 . Between the tubes a cooling fluid inlet channel 7 and a cooling fluid outlet channel 9 are formed, via which cooling fluid can be fed into the burner nozzle tip 1 or discharged from said burner nozzle tip. In particular water is considered as cooling fluid. In the region of the burner nozzle tip 1 , the outer burner element 2 deviates from a purely tubular shape and is inclined in the direction of the center of the burner outlet 3 . Furthermore, it has a cavity in the region of the nozzle ti...

Abstract

The tip has a burner tip portion (21) provided with a burner tip wall (21A). The burner tip portion is provided with a hollow space that extends to an end wall (47). The burner tip wall is provided with an inner side that faces toward the hollow space. A displacement body (15) is arranged in the hollow space. The displacement body is provided with an outer side that faces toward the inner side of the burner tip wall. A flow channel (20) is formed between the inner side of the burner tip wall and the outer side of the displacement body.

Description

technical field [0001] The invention relates to a burner tip, in particular for high temperature applications in synthesis gas generation plants. Furthermore, the invention relates to a burner, in particular a burner for a synthesis gas generation plant. Background technique [0002] A burner for a synthesis gas reactor is schematically described in DE 10 2008 006 572 A1. The synthesis gas reactor comprises an outer burner element, in the nozzle tip of which there is a cavity with an extrusion body arranged therein. Cooling water channels for cooling the burner nozzle tip are guided around the extruded body. The burner also includes an inner burner element disposed concentrically with the outer tube. A channel for conveying combustion dust, for example coal dust, is formed between the inner burner element and the outer burner element. In the region of its nozzle tip, the inner burner element also has a cavity with an extrusion body arranged therein in order to conduct co...
