Particulate fouling in gaseous waste heat-recovery processes reduces heat transfer efficiency and increases operational costs. This paper presents the industrial validation of developed equipment, building on earlier laboratory studies, to identify and characterize fouling capabilities in diverse applications. The device enables to work with a wide range of particulate deposition rates for different types of fouling particles and operating conditions such as temperatures, flow rates, and different heat transfer surface geometries. Industrial tests on operating process streams allow real-time assessment of fouling behavior. The results confirm the equipment’s capability to capture key fouling parameters, aiding process optimization reliably. Insights from the collected data support recommendations on heat exchanger geometry and operating conditions to mitigate fouling, helping extend equipment lifespan and reduce maintenance. Results of industrial validation confirm that the device can be used as a reliable and versatile tool to help the industry make better use of waste heat, save energy, and reduce problems associated with particulate deposition.
