Kind Code:
A
Abstract:
A method and device for continuously cleaning the pipe walls (2) of a heat exchanger (1), in which cleaning bodies, such as sand particles, are passed through a heat exchanger (1) together with a solids-laden gaseous medium to be cooled, Having passed the heat exchanger (1) the cleaning bodies are separated from the gaseous medium, collected in a vertically arranged elongated vessel (7), in which the cleaning bodies are brought in a fluidized state for removing contaminations and for generating a driving force, which is sufficient for recirculating the cleaning bodies to the heat exchanger.
