A heat exchanger cleaning system comprises: a target rotating body which rotates around a rotation axis; a first inlet through which first gas on the target rotating body is introduced; and a first soot blower located in the inner space of the first inlet and including a first injection port through which a first substance is injected and a second injection port through which a second substance is injected, wherein a first distance of the first injection port from the rotation axis is substantially the same as a second distance of the second injection port from the rotation axis. A heat exchanger cleaning method using the heat exchanger cleaning system comprises: a step for positioning the first soot blower; a step for spraying the first substance and the second substance at the same time; and a step for removing foreign substances.

Effluent containment devices are made of flame-resistant material having a Flame Spread Index of greater than zero and less than 30. The material may also have anti-static properties, such as being formed of a dissipative material or one that resists flow electrification.

A system (100) for servicing a heat exchanger is disclosed that includes a clog detection assembly (108) which further includes a light source (110) configured to be positioned on a first side of a component associated with the heat exchanger and illuminate the component. The clog detection assembly (108) further includes a light detector (112) configured to be positioned on a second side opposite the first side of the component to detect transmitted light and correspondingly generate a first signal. The system (100) further includes a processing device (102) communicatively coupled to the light detector (112). The processing device (102) analyzes the first signal to detect presence of a clog in association with the component. The processing device (102) may further cause a cleaning nozzle to move across the component, to perform a cleaning operation on the component.

A cleaning method for a heat exchanger is a cleaning method for a heat exchanger which includes a header passage and a plurality of internal passages connected to the header passage, that includes: a step of supplying a cleaning fluid, via the header passage, to some of the plurality of internal passages connected to the header passage, selectively.

A device and method for increasing accuracy in the determination of fouling in a heat exchanger in which heat is transferred from a first medium to a second medium, wherein a value for a variable characterizing the fouling is determined from a value for a first variable influenced by the fouling and a value for a second variable, where the second variable compensates for a change in the first variable caused by a change in flow of the first and/or second mediums through the heat exchanger, where the first variable can be a thermal transmission resistance, a thermal transmittance or a thermal transmission coefficient, where the first and second variable are determined from values measured totemperaturesr and flows of the first and second mediums without using material properties of the first and second mediums and structural properties of the heat exchanger when determining the first and second variables.

Disclosed are methods for cleaning of devices, such as heat exchangers, in particular to methods wherein machine learning systems, such as trained neural networks are used for indicating the fouling status the during the cleaning processes.
