When cleaning a boiler, what method is commonly used?

When cleaning a boiler, brushing and vacuuming is a commonly used method because it effectively removes soot, debris, and other buildup from the surfaces inside the boiler. The brushing action helps to dislodge any deposits that have accumulated, particularly in areas that are harder to reach. Following the brushing, vacuuming is employed to collect the dislodged materials, ensuring a thorough clean. This method not only improves the efficiency of the boiler but also helps to maintain safe operating conditions.

Using water for washing may not be appropriate due to the risk of causing corrosion or damage to sensitive components. Chemical cleaners, while effective in some scenarios, may not address all types of buildup found in boilers and often require careful handling and compatibility considerations. Sweeping and scraping can be less precise and might not adequately remove finer particles or reach tight spaces within the boiler system, making brushing and vacuuming a superior choice for effective and safe maintenance.
