Blowing Characteristics:

The lance with two opposite, high-performance nozzles helically moves intothe flue gas passthe flue gas pass.

The blowing process may begin as soon asthe two nozzles have passed through theboiler wall.

During the blowing process the lance tubecontinues to move helically into the flue gascontinues to move helically into the flue gaspass.

On reaching the front-side end position theg pdirection of movement changes and thelance tube returns to its starting position.
