Abstract:
This invention relates to a composition containing calcium and aluminum, preferably in the ratio Ca/3Al, or calcium and aluminum in combination with Si, preferably in the ratio between about Ca/3Al/2Si and Ca/3Al/4Si (all calculated as metal weights); and to the use of such composition in petroleum fuels which contain vanadium, particularly in combination with sodium, for example in residual fuels so as to inhibit corrosion in the system, particularly in gas turbines. These compositions are superior to magnesium as an additive to such fuels, particularly in fuels which are high in sodium.
Abstract:
This invention relates to chemical compounds or composite materials which, when exposed directly to an open flame, give the flame a sustained pre-determined color. Such chemical compounds can be used in a solid, jelly, liquid or gaseous form.
Abstract:
A gas turbine process includes supplying a fuel to a gas turbine, combusting the fuel in the gas turbine with a hot gas path temperature reaching at least 1100° C. during operation of the gas turbine, and supplying an inhibition composition including at least one yttrium-containing inorganic compound to interact with the vanadium and inhibit vanadium hot corrosion in the gas turbine caused by vanadium as a fuel impurity in the fuel. A process includes supplying an inhibition composition including at least one yttrium-containing inorganic compound to a hot gas path or a combustor of a gas turbine. A fuel composition includes a fuel including at least one fuel impurity including vanadium and an inhibition composition including at least one yttrium-containing compound. An atomic ratio of yttrium to vanadium in the fuel composition is in a range of 1 to 1.5.
Abstract:
A denatured fuel ethanol composition for blending with fuels, including gasoline and diesel fuel. The composition includes an ethanol composition comprising at least 92 wt. % ethanol; and from 95 wppm to 1,000 wppm isopropanol; and at least 1.96 vol. % fuel denaturant.
Abstract:
A process for operating a utility boiler. The process has the following steps: (a) providing fuel to the boiler; (b) providing one or more additives selected from the group consisting of (i) one or more slag control agents, (ii) one or more oxygen-generating agents, (iii) one or more acid mitigation agents, (iv) one or more fouling prevention agents, (v) one or more oxidizer agents, (vi) one or more heavy metal capturing agents, and (vii) any combination of the foregoing to the boiler or an auxiliary device thereof; (c) providing air to the boiler; (d) burning the fuel in the boiler to generate heat and an exhaust gas; (e) intermittently or continuously monitoring one or more physical and/or chemical parameters of the fuel and/or intermittently or continuously monitoring one or more emissions variables of the exhaust gas to obtain one or more values therefor; and (f) varying or maintaining the rate at which either or both of the fuel and the one or more additives are provided to the boiler based on the one or more values obtained.
Abstract:
A liquid fuel composition for a lamp for producing a colored flame is provided comprising: (a) a liquid fuel consisting substantially of ethylene glycol, and (b) a flame coloring agent such as boric acid or a metal compound capable of producing a flame of a determined color. Also provided are an oil lamp comprising at least one chamber containing the liquid fuel composition, with a pouring hole and one or more nozzles, and one or more wicks, each wick placed over the one or more nozzles and extending into the liquid composition; and kits for producing such oil lamps.
