Burner tile assembly.

摘要

A high-speed type burner tile assembly comprises a cylindrical mixing tile (2) having a central through-hole (10), and a combustion tile (3) having a tip portion (11) aligned with the mixing tile. The tip portion of the combustion tile is coaxially extended into the central cylindrical through-hole of the mixing tile to provide diffusion air delivery passages (14) extending parallel to the axis of the mixing tile between the tip portion and the inner surface of the through-hole of the mixing tile. This construction can supply a large amount of diffusion air at low pressure and can increase linearity of the combustion gas supplied into a furnace.
