Boiler chemical cleaning waste management manual ...

Abstract. Boiler chemical cleaning waste is generated during power plant outages when the water-side of the boiler and condenser tubes are cleaned to remove built-up scale and corrosion products that reduce heat transfer efficiency. The cleaning agents are designed to remove scale and deposits; thus the spent cleaning solutions contain dissolved and suspended metals such as iron and copper with lesser
