Abstract

Microstructural analysis of MgO-MgAl{sub 2}O{sub 4} refractory bricks corroded at 1,400--1,500 C by calcium aluminosilicate slag reveals secondary spinel, monticellite, merwinite, and MgO as microscopic corrosion products, generally forming in this sequence as the brick is penetrated. The secondary spinel forms an incomplete layer close to (but not at) the MgO grain. Thermodynamic calculations are used to support a detailed model of the corrosion mechanism.

Effects of alternate fuels Refractory Test Facility (RTF) test 1. Analysis of selected aluminosilicate refractory bricks, mortars, and fibrous insulations degraded by domestic residual oil combustion products

Technical Report Pasto, A.; Tennery, V.

Industrial conversion in the U.S. to alternate fuels from natural gas is presently underway and is anticipated to accelerate rapidly in the next few years. Currently the prime alternate fuels are distillate and residual oils. Conversion to residual oils for high-temperature process heat applications is anticipated to result in accelerated refractory and insulation corrosion and degradation due to reactions between fuel impurities and the ceramic linings of high-temperature equipment. Analyses are presented of several generic types of refractories and fibrous insulations which were exposed to residual oil combustion products under well-controlled conditions for times ranging from hundreds to thousands ofmore »« less

Influence of Al{sub 2}O{sub 3} Level in CaO-SiO{sub 2}-MgO-Al{sub 2}O{sub 3} Refining Slags on Slag/Magnesia-Doloma Refractory Interactions

Journal Article Chen, Liugang; Malfliet, Annelies; Jones, Peter; ... - Metallurgical and Materials Transactions. B, Process Metallurgy and Materials Processing Science

The influence of the Al{sub 2}O{sub 3} level in CaO-SiO{sub 2}-MgO-Al{sub 2}O{sub 3} (CSMA) stainless steel refining slags on the degradation of magnesia-doloma refractories was investigated through static refractory finger corrosion tests. The tests were performed at 1620 °C under Ar atmosphere, using slags with Al{sub 2}O{sub 3} contents of 5, 10, and 20 wt pct, respectively. The results indicate that the formation of 2CaO·SiO{sub 2} at the slag/refractory interface was suppressed by increasing the Al{sub 2}O{sub 3} content to 20 wt pct, thereby changing the corrosion mechanism from an indirect dissolution to a direct dissolution of CaO and MgO from the refractories.

Evaluation of ceramic refractories for corrosion behavior by molten slag-seed mixture of a coal-fired open-cycle MHD system

Technical Report Singh, R.; Kennedy, C.; Fousek, R.; ...

In an investigation of the possible use of a refractory material on the water walls of a radiant boiler in a coal-fired open-cycle MHD plant, the corrosion of a wide variety of commercial refractories was studied under reducing conditions at approx. 1500/sup 0/C in a coal-ash slag/potassium seed mixture. For several refractories, the results appear promising. Compared with earlier results obtained with slag only at approx. 1500/sup 0/C, the presence of approx. 10 mass percent K/sub 2/O seed in the Montana Rosebud slag did not result in increased corrosion, and may actually have improved the corrosion resistance of many ofmore »« less

De-SO sub x catalyst; The role of iron in iron mixed solid solutions spinels, MgO ter dot MgAl sub 2 minus x Fe sub x O sub 4

Journal Article Yoo, J; Bhattacharyya, A; Radlowski, C; ... - Industrial and Engineering Chemistry Research; (United States)

This paper discusses the iron mixed solid solution spinels, MgO {center dot} MgAl{sub 2{minus}x}Fe{sub x}O{sub 4}, prepared by the coprecipitation method, and the role of iron in these spinels examined for the de-SO{sub x} chemistry. The iron in the mixed spinels exhibited a dual function, namely, the catalytic oxidation of SO{sub 2} to SO{sub 3} and the dramatic lowering of the sulfate reduction temperature. In short, the iron mixed solid solution spinels performed much better as a de-SO{sub x} catalyst than their single solid solution counterpart without iron, Ce/MgO {center dot} MgAl{sub 2}O{sub 4}. The fractional substitution of the Almore »« less

Phase analysis program for magnesia refractories

Journal Article Tsambourakis, G - American Ceramic Society Bulletin

Dead-burned magnesia is one of the major raw materials used in the manufacture of refractories that does not melt below 2,500 C. The MgO content, in itself, is not the only factor that is industrially important. Impurity levels are equally important and can affect the slag resistance and high-melting-point properties of the product caused by the formation of low-melting phases, such as monticellite (CMS, CaMgSiO{sub 4} or CaO{center_dot}MgO{center_dot}SiO{sub 2}), merwinite (C{sub 3}MS{sub 2}, Ca{sub 3}Mg(SiO{sub 4}){sub 2} or 3CaO{center_dot}MgO{center_dot}SiO{sub 2}) and bredigite (C{sub 7}MS{sub 4}, Ca{sub 7}Mg(SiO{sub 4}){sub 4} or CaO{center_dot}MgO{center_dot}4SiO{sub 2}). The presence and proportion of these phases aremore »« less
