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.

保持管道无污垢被认为是工厂环境中热交换器和锅炉可靠、高效运行的关键因素。然而，随着时间的推移，不需要的物质**会自然沉积在管道的内表面上，从而导致腐蚀和管道故障，从而增加能量损失和维护**成本。因此，需要对特定地点的污垢物质进行调查，以确定污垢机制**并提出减轻污垢的最佳操作参数。**为此，新状态的首席研究员 Hyo-Jick Choi 博士-**阿尔伯塔大学（阿尔伯塔大学）的先进研究机构和 IRED Thermal Ltd（位于阿尔伯塔省的领先测试和检验服务提供商**）携手合作，调查特定地点的污垢物质。这种协同**合作提供了独特的技术实力和卓越的基础设施能力 - Choi 博士在材料科学、化学、生物技术和化学工程领域拥有超过 20** 年的多学科专业知识；**IRED Thermal Ltd 是研究污垢的先驱植物环境。因此，满足**该提案的目标并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/清洁功能补充 IRED 的核心产品组合，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结垢管，以确定结垢机制并确定**定量/定性结垢模式。这项研究将由一名研究员和一名**本科生进行，使用阿尔伯塔大学和**国家纳米技术研究所 (NINT) 提供的世界一流的表征设施。 IRED 将提供现场样本收集和**处理的实践培训。这项研究产生的附加功能将极大地促进**加拿大植物行业的卓越研究，为 IRED 及其客户带来经济效益，**并开创先进的污垢缓解诊断的新领域。
