Abstract
PURPOSE: To convey powdered coal through an anti-explosion mechanism by air.
CONSTITUTION: Powdered coal is taken out from a storage vessel 1 through a feeder 2 and drops into a conveyance pipe 3. The powdered coal is moved to the burner 6 of a furnace 5 by a rapid air flow from a blower 4 so that the powdered coal is burned. At that time, an open/close valve 7 is open position. When the pressure in the conveyance pipe 3 has become lower than that in the furnace 5 at the starting or stoppage of air conveyance equipment, a controller 11 operates on the basis of the output signal of a pressure detector 10 to stop supplying the powdered coal and close the valve 7 to shut off the flow in the conveyance pipe 3. When the pressure in the conveyance pipe 3 is lower than that in the furnace 5, the flame of the burner 6 is going to enter into the pipe 3 but the flame collides against the element 8 of the valve 7 and is cooled and extinguished by the heat transfer and accumulation of another valve element 9 made of a porous material.
