摘要
针对液化石油气家用燃气灶,提出将铸铁材质的引射器、燃烧器头部改用铝合金材质。对采用两种材质燃气灶的关键位置温升、热效率、折算热负荷进行了实测计算。采用铝合金材质时,引射器、燃烧器头部温升较高,但其他部位的温升未受影响,未对燃气灶的热效率、折算热负荷产生不良影响,折算热负荷仅有小幅下降。
Based on the principle of cathodic protection and the changes of the cathodic protection standards NACE RP 0169 - 1969, the minimum pro- tection potential and maximum protection potential for the cathodic protection criteria are analyzed. The differences, similarities and correlations among differ- ent standard versions of cathodic protection criteria are discussed. The various cathodic protection criteria are not exclusive, but rather complementary to form a complete evaluation system.
