Filed: 1980-08-22
Abstract: PURPOSE:To prevent a combustion chamber from unfavorable sludge deposition by forming a sludge layer exfoliating film utilizing difference between trends of ionization on surfaces of portions such as combustion chamber wall, etc. on which sludge tends of deposit. CONSTITUTION:A sludge layer exfoliating film 11 comprising heat resisting resin, etc. such as fluorine resin containing mixture of two kinds of flaky metal powders 8, 9 differing from each other in trends of ionization like combination of Zn and Al is formed on a surface such as wall surface of combustion chamber 4 on which sludge tends to deposit. When steam, sulfuric acid components, etc. in burnt gas permeates into sludge layer A formed on the surface of the film 11 to contact the film 11, local battery reaction is produced between metals 8, 9 in the film so that the metal power 9 having larger trend of ionization is corroded by reaction to water content. As this corrosive reaction proceeds, reaction product increases its volume larger than the original metal powder 9 and thickness of the film 11 locally increases. Thus, the layer A floats up from the surface of the film 11 and is eventually divided and exfoliated.
