Abstract (en)

[origin: JPH0686947A] PURPOSE: To prevent the formation of an explosive dust mixture by using an inert gas heated or preheated to a temperature higher than the dew point temperature of the residual moisture of a dust mixture during transportation or intermediate storage of the dust mixture. CONSTITUTION: Flue gas and hot process gas flow in a mill, drying plant and the moist explosive gas, dust mixture and more particularly coal dust mixture at fluidized transportation and storage of the dust generated are to be problem. The pressure portion of a refractory lining 6 is, thereupon, provided with a pipe coil 7 in the longitudinal direction of this lining. An inlet pipeline 8 and an outlet pipeline 9 for the additive external inert gas heated to the temperature higher than the dew point temperature of the hot process gas and the residual moisture of the dust mixture are connected to this pipe coil 7. The cold inert gas is supplied via a corresponding valve by the inlet pipe 8 and the outlet pipeline 9 is connected to a distribution system communicating with a storage bin or transporting pipeline.
