Abstract
This research paper introduces an automated online boiler cleaning system using compressed air as the cleaning medium to address the challenges posed by deposits on boiler surfaces in thermal power plants. These deposits, such as fouling and slagging, have a significant impact on plant performance, leading to reduced electricity generation capacity, decreased boiler efficiency, and increased maintenance costs. The proposed system utilizes real-time conditions within the boiler to initiate the cleaning process, ensuring effective heat transfer without causing damage to internal components. It consists of a monitoring and control system, along with a deposition removal technology. The monitoring system continuously assesses the level and distribution of deposits, providing feedback for optimal cleaning. The control system activates the cleaning process during boiler operation, maximizing cleaning efficiency while minimizing downtime. A case study conducted at the XYZ Thermal Power Plant in Zimbabwe validates the effectiveness of the system, demonstrating a remarkable improvement in plant availability by reducing forced outages caused by tube failures. Additionally, the system contributes to improved thermal efficiency, resulting in lower specific coal consumption and reduced emissions. The successful implementation of this automated online boiler cleaning system offers several benefits, including increased plant availability, reduced operational and maintenance costs, and enhanced environmental sustainability.
