Design of Automatic High-Pressure Water Jet Air Preheater Cleaning Device and Optimization of Online Cleaning Methods
Regenerative air preheaters are critical heat exchange components in coal-fired power plants and industrial boiler systems, but they are prone to ash and ammonium salt deposition, reducing efficiency and increasing energy consumption. This paper proposes an automatic cleaning device design based on high-pressure water jet technology and analyzes optimization paths for online cleaning methods. By optimizing nozzle layout, target distance control, and automation system integration, the device addresses issues of uneven cleaning, low efficiency, and metal damage in traditional methods. Experiments and case studies demonstrate that the device significantly reduces air preheater pressure differences, improves heat recovery efficiency, and prevents secondary issues such as filter bag adhesion. Air preheater fouling, caused by ash and viscous ammonium bisulfate (ABS) deposits, remains a persistent issue in power generation and industrial boiler systems. Traditional manual cleaning methods are labor-intensive, inefficient, and pose safety risks. In contrast, automated high-pressure water jet systems offer a robust solution for continuous operation. This article explores the design principles, technical advancements, and practical implementations of such systems, emphasizing their role in enhancing boiler efficiency and reducing downtime.
