Abstract

802,060. Preventing scale in economizers. NATIONAL ALUMINATE CORPORATION. Oct. 16, 1956 [Oct. 26, 1955], No. 31441/56. Class 123(1) Scale formation in economizers of steam boilers is prevented by adding for example 60-200 milli-grammes per litre of a mixture containing 40-60 per cent by weight of acidic polyhydroxy aromatic compounds and 10-20 per cent by weight of neutral inorganic salts to the feedwater. The mixture may also contain lignin materials, for example, sodium lignosulphonates and anti-foaming ingredients. Glucoside esters which are hydrolizable into polyhydroxy compounds or salts of a weak base containing a polyhydroxy aromatic nucleus may be also used in the mixture.
