Zusammenfassung:	1,255,304. Electrostatic separators. FRIED KRUPP G.m.b.H. 28 Aug., 1970 [29 Aug., 1969], No. 41627/70. Heading B2J. A method of preventing dust deposits on the gas-washed insulators of an electrostatic filter in which pyrophoric dust from CO- containing converter waste gases is precipitated in a reducing atmosphere consists in supplying to the insulators a hot oxidising gas at a temperature such that its density is less than that of the gas to be freed from dust. As shown apparatus for carrying out the method comprises a burner 9 supplied with fuel from a pipe 10. Air is added to the burnt fuel through a pipe 12 by a blower 13. The oxidising gas flows through a pipe 15 to a housing containing the insulator 4.
