<p><P>PROBLEM TO BE SOLVED: To provide a method for preventing the fluctuation of pressure in a carbonization chamber in the charging of powdery material with a gas, especially preventing the pressure fluctuation at the start of charging and the end of charging causing large pressure fluctuation. <P>SOLUTION: The fluctuation of the pressure in a carbonization chamber is prevented in the case of feeding a powdery material under pressure into the carbonization chamber of a coke oven using a forced feeding apparatus provided with a gas-boosting apparatus, a forced feeding tank, a supplying apparatus for carrier gas of the powdery material, a gas supplying apparatus, a powder-separating apparatus, an exhaustion apparatus and a charging door to open and close the powder-charging port of the carbonization chamber. The charging door is opened after adjusting the quantity of supplied gas from the gas supplying apparatus to be equal to the quantity of exhaust gas, the supplied gas quantity is readjusted to be larger than the exhaust gas quantity and the powder is forcibly fed from the forced feeding tank with pressure. The supplied gas quantity from the gas supplying apparatus and the exhaust gas quantity are adjusted also at the end of forced feeding of the powder. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
