摘要
The burner is mounted in a cylindrical sleeve (4) which is included in the base of the furnace. The gas is admitted in the pipe (14) to an external manifold (13). The gases passes through the holes (15) into the burner. The air is admitted through the annular passage (11), the air gas mixture being aspired by a motor driven fan (10). The mixture is forced into the burner which consists of two concentric cylinders, fitted inside the main cylinder. Each cylinder including the main one, is perforated, and combustion takes place outside the burner. Secondary air is admitted through the annulus (3).
