Abstract

A boiler comprises: a burner (1) connected to a stoking piping (2) fitted with a solenoid valve (3) which closes or opens the stoking; a combustion chamber (4) open toward the room housing the burner; a hood (6) for a chimney (7) with a cavity (8) open toward said room; a first temperature sensor (10) located below the burner (1); a second temperature sensor (11) is located near the cavity (8); the first and second sensors (10,11) are electrically connected to a safety device (12) for boilers, via a first conductor (13) and a second conductor (14), respectively. The device (12) is connected to a generator (15) and to solenoid valve (3) by means of a third conductor (15) and of a fourth conductor (17), respectively.
