Maintaining fouling-free tubes is considered a critical factor for reliable and efficient operation of heat**exchangers and boilers in plant settings. However, time-dependent natural deposition of unwanted substances**on the interior surface of tubes leads to the corrosion and tube failure, increasing energy loss and maintenance**costs. Therefore, investigation of site-specific fouling substance is required to identify the fouling mechanisms**and to propose optimal operational parameters for mitigation of fouling.**To this end, Dr. Hyo-Jick Choi, principal investigator of a new state-of-the-art research facility at the**University of Alberta (U of A), and IRED Thermal Ltd, a leading provider of testing and inspection services**based in Alberta, have come together to investigate site-specific fouling substances. This synergistic**collaboration offers unique technical strength and excellent infrastructure capability- Dr. Choi has over 20**years of multidisciplinary expertise in materials science, chemistry, biotechnology, and chemical engineering;**IRED Thermal Ltd is a pioneer in investigating fouling in a plant setting. As a result, the probability of meeting**the objectives of this proposal and realizing an innovative solution is high. Findings of this research will**supplement IRED's core portfolio with diagnostic/cleaning capabilities, enabling IRED to provide the**diagnostic service to a plant facility along with existing inspection service.**Dr. Choi and his lab will analyze the site-specific fouled tubes to determine the fouling mechanism and identify**quantitative/qualitative fouling patterns. This research will be carried out by a research associate and an**undergraduate student, using world-class characterization facilities available at the University of Alberta and**National Institute for Nanotechnology (NINT). IRED will provide hands-on training for the collection and**handling of on-site samples. Added capabilities emanating from this research will substantially promote**research excellence in Canadian plant industries, providing economic benefits to the IRED and its customers,**and ushering in a new area of advanced fouling mitigation diagnostics.

维持无污染管被认为是在工厂环境中可靠和有效地运行热量和锅炉的关键因素。但是，不需要物质的时间依赖性自然沉积**在管的内部表面上导致腐蚀和管失败，增加了能量损失和维持**成本。因此，需要对特定地点结垢物质进行调查，以确定污染机制**，并提出最佳的操作参数以减轻污染。艾伯塔省（Alberta）聚集在一起研究特定地点的污染物质。这种协同的**合作提供了独特的技术实力和出色的基础设施能力 - 崔博士拥有20多年的材料科学，化学，生物技术和化学工程学的多学科专业知识；结果，达到本提案的目标和实现创新解决方案的可能性很高。这项研究的结果将通过诊断/清洁功能来补充IRED的核心投资组合，使IRED能够为工厂设施提供**诊断服务以及现有的检查服务。** DR。 Choi和他的实验室将分析特定地点的污染管以确定污染机制并确定**定量/定性犯规模式。这项研究将由研究助理和**本科生进行，使用艾伯塔大学的世界一流表征设施和**国家纳米技术研究所（NINT）。 IRED将为收集和处理现场样品提供动手培训。从这项研究中获得的增加功能将大大促进加拿大植物工业的卓越研究，从而为IRED及其客户提供经济利益，并迎来了高级缓解缓解诊断的新领域。
