Abstract
A method and apparatus is provided for controlling a variable feed rate of a lance on a cleaning device for cleaning one or more tubes in a heat exchanger. Different regions of the tubes within the heat exchanger are identified as hotter regions and cooler regions depending on a temperature gradient of fluid moving through the heat exchanger. The hotter regions tend to develop more fouling on the inner surface of the tube. The lance uses the variable feed rate to spend more time cleaning the hotter regions with more fouling than the cooler regions with less fouling. This enables a more optimized cleaning profile to be implemented to efficiently clean the tubes in the heat exchanger.
