Suitability of Indian Coal For Coal-Fired MHD Generators
The electrical conductivity of seeded (with potassium) combustion products of six varieties of Indian coal with enriched air have been analytically evaluated to investigate the feasibility of using them as working fuels for coal-tired MHD generators. The analysis takes into account the effect of sulphur and ash on the conductivity of combustion products.
متن کاملCombustion kinetics of coal chars in oxygen-enriched environments
Oxygen-enhanced and oxygen-fired pulverized coal combustion is actively being investigated to achieve emission reductions and reductions in flue gas cleanup costs, as well as for coal-bed methane and enhanced oil recovery applications. To fully understand the results of pilot scale tests and to accurately predict scale-up performance through CFD modeling, accurate rate expressions are needed to...
متن کاملSurface characterisation of synthetic coal chars made from model compounds
Knowledge of surface properties is essential for understanding the reaction mechanisms involved in several coal conversion processes. However, due to the complexity and heterogeneity of coal this is rather difficult and the use of known model compounds could be a valuable tool. Single model compounds have been widely used, but they give a quite simplified picture. In this work a mixture of mode...
متن کاملCO2 Gasification Reactivity of Chars Derived From Zhundong Coal
Coal gasification with carbon dioxide is a process for generating clean gaseous fuels and relieving greenhouse effect. Zhundong coal has high alkali and alkali earth metals (AAEMs) content, medium volatile and low ash in nature. Isothermal CO2 gasification of char derived from Zhundong coal (R-char) and char from acid washing R-char (AR-char) are performed in thermo-gravimetric analyzer (TGA). ...
متن کاملExperimental Study of Hydrogasification of Lignite and Subbituminous Coal Chars
The experimental facility for pressure hydrogasification research was adapted to the pressure of 10 MPa and temperature of 1300 K, which ensured repeatability of results and hydrogen heating to the process temperature. A hydrogasification reaction of chars produced from two rank coals was investigated at temperatures up to 1173 K, pressures up to 8 MPa, and the gas flow rates of 0.5-5 dm(n)(3)/...
