AUTOMATIC SAFETY DEVICE FOR TRAVELLING GRATE BOILER WHICH USES A SOLID FUEL

摘要

At the base of the hopper (2) feeding a burner (1) with coal there is mounted, on a shaft (5), a moveable obturating flap (4) which a counterweight (14) tends to move into a closed position against the retaining force of an electromagnetic clutch mechanism combined with a toothed sector gear (9) having a retaining finger (10), this clutch mechanism being controlled by a centralising apparatus connected to various sensors monitoring the running of the burner (1), any anomaly resulting in the closing of the moveable flap (4).
