High-temperature corrosion and wear of boiler water wall tubes have always been serious problems that are widespread in power systems

High-temperature corrosion and wear of boiler water wall tubes have always been serious problems prevalent in power systems. Their direct hazards mainly lie in two aspects: 1) Thinning of the tube walls, with an average annual thinning rate of around 1 mm; in severe cases, this rate can reach 5–6 mm per year. This creates serious risks to safe operation, increases the workload related to temporary repairs and major overhauls in power plants, and results in significant economic losses for these facilities. 2. A sudden tube burst in the water wall occurred, forcing an emergency shutdown for repairs. This not only disrupted the normal power generation operations of the power plant and reduced its revenue from power production, but it also increased the workload on the workers and led to additional repair costs. It had a direct impact on the profitability of the enterprise, while at the same time disturbing the normal operation of the regional power grid and affecting local industrial and agricultural activities, thus causing significant social consequences as well.
Your statement is already very clear. For further summary, refer to the following concise overview: High-temperature corrosion and wear of boiler water wall tubes are serious problems that are common in power systems. Their main consequences include: 1. Significant thinning of the tube walls (typically about 1 mm per year; in severe cases, 5–6 mm per year), which creates safety hazards and increases the workload for maintenance as well as resulting in economic losses. 2. It may cause sudden tube failures, leading to emergency shutdowns for repairs, disrupting the normal operation of the power plant, reducing the company’s profitability. It also affects the proper operation of the regional power grid as well as local industrial and agricultural production, resulting in significant social impacts. .
