PROBLEM TO BE SOLVED: To provide a method for preventing the corrosion of an injection pipe in a pulse-jet type bag filter apparatus and the pulse-jet type bag filter apparatus the injection pipe of which does not corrode. SOLUTION: Exhaust gas is prevented from intruding into the injection pipe by making compressed air flow in the injection pipe even when the compressed air is not jetted so that the pressure of the inside of the injection pipe is kept higher than that of the outside. An exhaust gas purging pipe and a flow rate regulating valve are arranged on the injection pipe of the pulse-jet type bag filter apparatus. COPYRIGHT: (C)2004,JPO&NCIPI
