Abstract
(EN)
The present disclosure relates to a device for reducing fouling in tubes of a heat exchanger and heat exchangers comprising such anti-fouling device(s). The anti-fouling device comprises an elongated displacement body insertable in the heat exchanger tube to reduce the flow cross-sectional area in a portion of the tube. It further comprises a mount 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 disclosed anti-fouling devices effectively reduces fouling in heat exchangers in a reliable manner over an extended period of time without requiring maintenance or external controls, can be provided at relatively low cost, is easily installable and can be retrofitted also to existing heat exchangers. It is particularly useful for mitigating 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.
