Abstract:
A method of removing dust from a combustion gas, comprising:channeling said combustion gas to a dust collecting apparatus including a ceramics filter, said ceramics filter having an inlet end and an outlet end wherein a differential pressure across said ceramics filter is defined as a difference between an inlet pressure of said combustion gas at said inlet end and an outlet pressure of said combustion gas at said outlet end, said combustion gas being channeled to said dust collection apparatus at an inlet flow rate;supplying a de-sticking agent comprising at least one of a group consisting of MgO, MgCO.sub.3, and Mg(OH).sub.2 into said combustion gas upstream of said ceramics filter; andregulating said supplying of said de-sticking agent in relation to one of said differential pressure across said ceramics filter and said inlet flow rate of said combustion gas so as to reduce an attraction between particles in said ceramics filter and reduce said differential pressure across said ceramics filter.
