“…One of the ways to resist corrosion is to use alloys that resist the corrosion process, especially hot ones, that remove vanadium and sulfur from the fuel before burning it [5,6]. The removal sediment process is carried out by adding capable chemical compounds to raise the melting point and change the structure of the sediment, and this is exactly what happens when add container compounds on magnesium, often when any compound containing magnesium is burned, it passes through the oxide layer It decomposes and tries to bind with oxygen to form magnesium oxide (MgO), which is inhibited by molten sodium Vanadyl Vanadates by the formation of magnesium compounds Magnesium Vanadate (MgxVyOZ) which melts at degrees higher than (C) 1000), and this degree, as it is known, is higher than the degrees Thermal heat formed in the combustion chambers of turbines and commercial boilers fuel, and magnesium oxide (MgO) is A qualified for this role [7,8]. The surveyed studies showed that there is a significant effect for the used fuel on the power plant performance and gas turbine durability.…”

The current review focuses on the utilization of heavy fuel in operating gas turbine and their effect on the power plant performance. The literature survey includes a comparison of the different studies to reveal the effect of the fuel property on the combustion efficiency and fuel consumption. the most important of which is the generation of electric power by heavy fuels in power stations that use turbines. Gas turbine is becoming increasingly widespread in electric power generation and other branches of industry. It is known that the thermal efficiency of an open gas turbine cycle varies according to the type of fuel used in the plant. Gas turbines are particularly suitable for fuels with materials that have physical and chemical properties that help in continuous combustion and therefore the ease inherent in Fuel injection and mixture preparation.

“…The main objective of corrosion inhibitors is to stabilize V by trapping it in new compounds with a high melting point and low chemical reactivity. To date, the most commonly used corrosion inhibitor is based on magnesium compounds that, when reacted with vanadium salts, form the refractory compound Mg 3 (VO 4 ) 2 (melting point of 1074 °C) [7,8,9,10,11]. However, its inhibition capacity is compromised if the S content of the fuel is high [12,13].…”

Rare Earth-Based Compounds as Inhibitors of Hot-Corrosion Induced by Vanadium Salts

In this study, the performance evaluation of lanthanum compounds as corrosion inhibitors of vanadium salts was performed. The inhibitors tested were lanthanum acetate and La2O3. The performance of the inhibitors was tested using sodium metavanadate (NaVO3) as a corrosive medium at 700, 800, and 900 °C. The corrosion inhibitory effect was evaluated on the corrosion process of 304H stainless steel. The corrosion rate of the steel was determined by the mass loss technique after 100 h of immersion in the corrosive salt with and without the addition of the corrosion inhibitor. The results show that lanthanum compounds act as corrosion inhibitors of vanadium salts. The inhibitory effect increases by increasing the concentration and tends to decrease when increasing the test temperature. Lanthanum compounds act as excellent corrosion inhibitors due to their ability to stabilize vanadium cations. Vanadium is stabilized by forming a new compound, lanthanum vanadate (LaVO4), with a melting point much higher than the compounds formed when Mg or Ni compounds are used as corrosion inhibitors.

“…As a method of promoting liquid fuel combustion processes, fuel additives were utilized as octane number improvers, detergents, oxygenates, emission depressors, corrosion inhibitors, and dyes. Many kinds of fuel additives have been studied, including magnetic nanofluids, nano-organic compounds, polymers, nanoparticles, − and so on. In these additives, hydrocarbon additives are generally used because of their low cost, comparatively good miscibility, and high oxygen content and because they are free of other chemical elements.…”

Combustion Mechanisms and Kinetics of Fuel Additives: A ReaxFF Molecular Simulation

Fuel additives are widely used as octane number improvers, oxygenates, emission depressors, and corrosion inhibitors to promote combustion processes of liquid fuel. In this work, six kinds of fuel additives, including ethanol, butanol, dimethyl carbonate, dibutyl carbonate, methyl tert-butyl ether, and tri-tert amyl glycerol ether, were studied by ReaxFF molecular dynamics simulations. The bond dissociation reactions were found to be more dominant at the early stage than oxidation reactions, which means the unimolecular reactions were the main pathways of primary reactions in hydrocarbon combustion. The rate constants of primary reactions of ethanol combustion were much smaller than those of other systems, which were in good agreement with the product distribution analysis and previous work. The main reaction pathway and relative rate constants for all systems were evaluated. Four kinds of main radicals, including ·CH3, ··CH2, ·OH, and ·HO2, were detected, and the number variation with time are presented. The number of ·OH radicals was the largest among those four radicals, and it was found to gradually increase with time except for ether systems; the number of ·CH3 and ··CH2 radicals sharply increased first and then gradually decreased. Hopefully, the results obtained in this work will be helpful to future design and screening of new fuel additives.
