| 摘要 |
<p>The invention relates to a tubular burner (1) for industrial furnaces (2). Said burner comprises an end section that extends into a combustion chamber (7) which is supplied with secondary combustion air (6). It also comprises a plurality of separate annular supply channels for combustion gas (9) and fuel (8) which are limited by tubular walls that are coaxially nested into one another. Individual nozzles (16) are distributed in a substantially ring-shaped configuration on the front face (17) of the combustion gas supply channel that faces the combustion chamber. In order to achieve a good combustion gas/combustion air fuel ratio, at least one outer annular supply channel (13) is substantially configured as a fuel supply channel while the combustion gas supply channel that is provided with individual nozzles is mounted radially (11) within said fuel supply channel.</p> |
