Industrial boiler cleaning requires choosing between sandblasting and slag removal methods, each serving distinct maintenance needs. Sandblasting uses high-velocity abrasive materials for comprehensive surface cleaning, removing corrosion, scale, and deposits while preparing surfaces for inspection. Slag removal targets specific hardened combustion deposits through chemical, thermal, or mechanical approaches. The optimal method depends on boiler type, fuel source, deposit characteristics, and downtime constraints. Coal-fired boilers typically need aggressive slag removal, while gas-fired units may require gentler sandblasting approaches. Professional assessment ensures the right technique for maintaining heat transfer efficiency and minimizing maintenance costs.
