System for connecting burners to chimney with coaxial pipe

摘要

Each burner has a coaxial pipe (4) leading from the burner to the chimney (5). The inner pipe (7) of the coaxial pipe is connected to a chimney flue gas pipe (8), while the outer pipe (6) is connected to a chimney-air pipe (10). The chimney wall(9) has a first and at least one second opening for the same number of fireproof sleeves. The inner pipe of the coaxial pipe goes through the first fireproof sleeve. A pipe socket (11) goes through the second fireproof sleeve and is connected to the outer pipe of the coaxial pipe.
