Özet

The oxidation behaviours of three different steels used in the construction of petroleum refinery heaters were investigated by thermogravimetric analysis (TGA) technique. C-5, P-11 and P-22 steel samples were tested in two different environments: air and CO2+2H2O+7.52N2, a gas composition which simulates the combustion products of natural gas, at 450 and 500 degrees C. P-22 steel had the best oxidation resistance at both temperatures in air. In CO2+2H2O+7.52N2 environment, the oxidations of all the steels were accelerated and C-5 exhibited better oxidation resistance than P-22 and P-11.
