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.

Investigation of co-combustion characteristics of low quality lignite coals and biomass with thermogravimetric analysis Varol, Murat; Atımtay, Aysel; Bay, B.; Olgun, H. (2010-10-20) In this study, combustion and co-combustion characteristics of three biomass fuels and three Turkish lignite coals were investigated by using a thermo gravimetric analyzer. There are just a few studies investigating the co-combustion characteristics of coal and biomass, and the synergistic effect of their various combinations on the peak temperatures and burnout times.
Influence of transverse crack width on reinforcement corrosion initiation and propagation in mortar beams Sahmaran, Mustafa; Yaman, İsmail Özgür (Canadian Science Publishing, 2008-03-01) This paper discusses the relationship between crack widths, chloride diffusivity, and corrosion rate of cracked mortar beams. Flexural loads are introduced to generate crack widths ranging from 29 to 390 mu m. The specimens were subjected to accelerated corrosion by immersion in a 5% NaCl solution and a constant voltage of 12 V. In addition, salt ponding tests were conducted to determine the chloride ion transport properties. The results showed that as the crack width increased, the effective diffusion coef...
Effect of chromium on the oxidation of steels used in the construction of petroleum refinery heaters Sultan, Abdelrahman Saleh; Karakaya, İshak; Department of Metallurgical and Materials Engineering (2013) Low chromium steels used in the construction of petroleum refinery heaters work in flue gas environments containing water vapor. On the other hand, the higher oxidation rates of chromium containing steels in moist atmospheres have been reported. P-5, P-22, P-11(containing 5, 2.25 and 1.25 %Cr) and C-5 steels, used in petroleum refinery construction, were subjected to isothermal oxidation tests. These steels were tested in two different environments; air and flue gas of natural gas combustion -CO2+2H2O+7.52N...
Influence of reservoir rock composition on the combustion kinetics of crude oil Kök, Mustafa Verşan (Springer Science and Business Media LLC, 2009-08-01) In this research, the effect of different lithology (limestone and sandstone) on the combustion of light crude oils was investigated using thermal analysis techniques. Three distinct reaction regions were identified in all of the crude oil+limestone and sandstone mixtures, known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO), respectively. Kinetic analysis of the crude oil+limestone and sandstone mixtures was performed using Coats and Redfern method and the res...
Influence of fly ash composition on non-gray particle radiation in combusting systems Ates, CİHAN; Selçuk, Nevin; Külah, Görkem (2018-08-01) In this study, chemical composition dependency of both radiative properties of ash particles and radiative heat exchange are investigated for conditions typically encountered in industrial coal-fired furnaces. For that purpose, chemical composition dependent / independent complex index of refraction models are utilized to evaluate (i) spectral particle absorption efficiencies, scattering efficiencies and asymmetry factors, (ii) particle cloud properties representing pulverized coal fired furnaces (PC-Fired)...
