Abstract (en)
[origin: WO2007006293A1] The invention relates to a method for cleaning the flues or similar of combustion systems, especially for cleaning the heat exchangers and membrane walls located in the flues of furnaces of power plants during operation of the furnace. Methods known in prior art are suitable only to a limited extent for cleaning during operation of a furnace because the hot internal fittings placed in the furnace are distorted and the heat exchangers tend to lose their sealing capacity. According to the novel method, fine-grain, solid material which is blown against the surfaces that are to be cleaned with the aid of compressed air is used as a cleaning medium.
