Abstract
Methods and systems for cleaning inner surfaces of tubes in a heat exchanger. Some systems include a cleaning device having a nozzle configured to inject cleaning fluid into first and second tubes to perform different first and second cleaning cycles on the tubes, respectively, a controller configured to determine delivery parameters for the cleaning cycles based on a characteristic of each tube, and to control the cleaning device to perform the cleaning cycles based on the delivery parameters. Some methods include determining, with a controller, a tube in the heat exchanger engaged with a nozzle of a cleaning device for injecting a cleaning fluid into the tube during a cleaning cycle, a characteristic of the tube, and a delivery parameter of the cleaning cycle for the tube based on the characteristic of the tube; and performing the cleaning cycle for the tube based on the delivery parameter.
