使得过热器化学清洗具有可行性。
Abstract
The technical difficulties of chemical cleaning were analyzed
such as insoluble ferric oxides
corrosion controlling and blockage in vertical bend tube.Thus
the composition and technique of chemical cleaning using recombination citric acid was developed.This cleaning solvent can dissolve oxides scale rapidly with little exfoliation and no blockage in U-type or W-type tubes.Moreover
it has extremely low corrosion rate on metal
and has no bad effect on the super heating system.Thus
