| 摘要 |
The invention relates to a burner, particularly for the gasification of solid carbonaceous materials by partial combustion. The burner comprises a central channel (2) and at least one coaxial channel (6), the channels leading from a upstream supply side to a downstream discharge end. The channels (2, 6) are defined by concentric walls (3, 5) having free downstream outer ends profiled to define an annular slit (10) forming a discharge end of the coaxial channel (6) and converging towards an adjacent discharge end of the central channel (2). A connection block (11) intersects at least the coaxial channel (6), and optionally also present cooling jackets. The block (11) is provided with one or more openings (12) in line with the corresponding channel parts at both sides of the block (11). |
