Abstract:
1. A method of cleaning heat exchange surfaces of a heat exchange system, comprising the steps of: (a) leading an exhaust gas stream by the heat exchange surfaces of a heat exchange system; (b) performing a cleaning cycle on the heat exchange surfaces by cleaning sequentially differently located parts of the heat exchange surfaces with cleaning equipment having an operation parameter status, wherein respective particles are released sequentially from each of the differently located parts being cleaned, and the released respective particles associated with each of the differently located parts being cleaned are entrained sequentially with the exhaust gas stream; (c) measuring the amount and/or type of the respective particles sequentially entrained with the exhaust gas stream so as to create particle measurement data associated with each of the respective differently located parts of the heat exchange surfaces cleaned during a cleaning cycle, and (d) linking together and storing into an electronic memory location information of the respective differently located parts of the heat exchange surfaces that are cleaned during the cleaning cycle and the respective particle measurement data created during the cleaning cycle so as to create fouling information related to fouling on the respective differently located parts of the heat exchange surfaces as a function of the location of the respective differently located parts of the heat exchange surfaces.
