Effects of Turbulent Mixing and Controlling Mechanisms in an Entrained Flow Coal Gasifier

There is a large range of time and length scales of turbulent fluctuations in an entrained flow coal gasifier. To figure out the turbulent effects on coal gasification processes and the controlling mechanisms of different regions in an entrained flow coal gasifier, the characteristic time and length scales for all major processes are estimated.On the basis of the comparisonbetween the length/ti...

Water - Gas Shift Modeling of Coal Gasification in an Entrained - Flow Gasifier

Most of the reaction rates for the water-gas shift (WGS) reaction were obtained from experiments under simplified laboratory conditions with specific catalysts. A few of the reaction rates without using catalysts were obtained under supercritical (water) conditions, with the pressure much higher than those in a typical gasifier. In either case, it is not clear how the published reaction rates c...

Formation characteristics of aerosol particles from pulverized coal pyrolysis in high-temperature environments.

The formation characteristics of aerosol particles from pulverized coal pyrolysis in high temperatures are studied experimentally. By conducting a drop-tube furnace, fuel pyrolysis processes in industrial furnaces are simulated in which three different reaction temperatures of 1000, 1200, and 1400 degrees C are considered. Experimental observations indicate that when the reaction temperature is...

New Correlations for Coal and Biomass Pyrolysis Performances with Coal-Biomass Type Number and Temperature

The pyrolysis of coal and biomass is generally reported as the mass yield of released chemicals at various temperatures, pressures, heating rates and coal or biomass type. In this work, a new coal-biomass type number, NCT, is introduced. This number is constructed from the mass fractions of carbon, hydrogen, and oxygen in the ultimate analysis. This number is unique for each coal or biomass typ...

Pulverized Coal Combustion: the Influence of Flame Temperature and Coal Composition on Thermal and Fuel

A laboratory combustor was used to investigate the factors that influence the conversion of fuel nitrogen in coal during coal combustion. Fuel NO was isolated by experimentation utilizing Argon/Oxygen/Carbon Dioxide mixtures as the oxidant, and care was taken to compare cases with air at matched conditions. For both well mixed and slowly mixed flame types, fuel NO contributed over 75% of the to...
