Air/exhaust gas structure for a burner has an inner exhaust gas outflow pipe aligned at the required angle with clip rings within a horizontal channel for the air flow to be covered when in place

摘要

The channel for air and exhaust gas at a combustion system, which is independent of its local environment air, has a channel section (1) at the chimney composed of an outer pipe to carry the air flow and an inner pipe (5) for the exhaust gas outflow. The outer pipe has a longitudinal channel (6), mounted to the wall, with clip rings (9) to hold the inner pipe (5). The holders give a defined angular pitch to the exhaust pipe (5) within the horizontal outer pipe and, when in place and in the required alignment, the channel is covered.
