Description

Technical Field

[0001] This utility model belongs to the field of ash removal technology, specifically a waste heat boiler ash removal device. Background Technology

[0002] Waste heat boilers are boilers that utilize waste heat generated during industrial production to produce steam. Their core function is to recover and utilize high-energy-consuming waste heat that would otherwise be lost to the environment, significantly improving energy efficiency, reducing production costs, and minimizing environmental pollution from waste heat emissions. However, dust, particulate matter, and oil in the flue gas easily adhere to the inside of the boiler, forming ash deposits. These ash deposits severely affect heat transfer efficiency, leading to a decrease in boiler output. Therefore, regular ash removal is necessary to ensure efficient and stable boiler operation. Currently, ash removal for waste heat boilers typically involves spraying ash removal agents, but these agents cannot be sprayed evenly and comprehensively, resulting in defects in the ash removal operation. Therefore, improvements are needed to address these issues. Utility Model Content
