Abstract

PURPOSE: To provide the silencer with a function as an automatic damper while improving silencing effect by a mechanism wherein a blast fan is mounted and resistance by blast air pressure is formed.
CONSTITUTION: A blast fan 4 is also driven at the same time as a burner when lighting the burner, but since the blast fan 4 does not reach full revolution yet exhaust gas is exhausted to the outside through the whole inside of the first inner cylinder 6 and the second inner cylinder 9, and a sudden inner pressure rise in case of ignition is moderated. When a fixed time passes after ignition, the blast fan 4 is fully rotated, air pressure is generated between the first inner cylinder 6 and the second inner cylinder 9, and air resistance is formed. Thus, combustion exhaust gas is exhausted to the outside only through the inside of the second inner cylinder 9, a diamter of exhaust becomes smaller, and the leakage of sounds to the outside can be reduced.
