Abstract
An anti-fouling device includes an elongated displacement body insertable in a heat exchanger tube to reduce the flow cross-sectional area in a portion of the tube. A mount is connected to the elongated displacement body for attaching the device to an end of the heat exchanger tube. The mount is configured to hold the displacement body, when inserted into the tube, in a spaced relationship to the inner surface of the tube. The device reliably reduces fouling over an extended period of time without requiring maintenance or external controls, is easily installable, and can be retrofitted to existing heat exchangers. The device mitigates fouling related issues in heat exchangers subjected to hot combustion or process gases such as those encountered in the production of carbon black, fumed silica or other particulate matter, without contaminating the product recoverable from the process gas or having an adverse influence on the properties thereof.
