Feasibility Studies of in-Situ Coal Gasification in the Warrior Coal Field. Quarterly Report

Description: Studies in support of in-situ gasification involved experiments in bench-scale combustors where three parameters were varied independently: initial fuel bed temperature, applied air flow and water vapor influx rate. Methods for measuring the thermal conductivity of solids at high temperatures were evaluated and measurements of the thermal conductivity and thermal diffusivity were made over a temperature range for several samples of coke.

Feasibility Studies of in-Situ Coal Gasification in the Warrior Coal Field. Quarterly Report

Description: Laboratory studies on a research combustor were used in an attempt to determine the length of oxidation and reduction zones. Unfortunately the buoyant effects of the heated gases caused the burn to proceed along the upper portion of the horizontal combustor. This made the interpretation of uncertain value. Methods of measuring the thermal conductivity and chemical reactivity of coke are discussed. A bibliography of the physical and chemical properties of coke is appended. (LTN)

Feasibility Studies of in-Situ Coal Gasification in the Warrior Coal Field. Quarterly Report

Description: Because of high internal temperatures, the external temperature has no effect upon the reaction rate of coke particles with air for temperatures above 750/sup 0/K. Reactions could not be initiated below that temperature. Chemical reaction rate was not found to be a rate-controlling step: both extra-particle and intra-particle diffusion are important and limit the rate of oxidation. The observed values of k/sub c/, the extra-particle mass transfer coefficient were found to be in good agreement w… more

Novel Corrosion Sensor for Vision 21 Systems Annual Report: 2005

Description: Advanced sensor technology is identified as a key component for advanced power systems for future energy plants that would have virtually no environmental impact. This project intends to develop a novel high temperature corrosion sensor and subsequent measurement system for advanced power systems. Fireside corrosion is the metal loss caused by chemical reactions on surfaces exposed to the combustion environment. Such corrosion is the leading mechanism for boiler tube failures and has emerged to… more

Displacement Cascades in Diatomic Materials

Description: A new function, the specified-projectile displacement function p/sub ijk/ (E), is introduced to describe displacement cascades in polyatomic materials. This function describes the specific collision events that produce displacements and hence adds new information not previously available. Calculations of p/sub ijk/ (E) for MgO, Al/sub 2/O/sub 3/ and TaO are presented and discussed. Results show that the parameters that have the largest effect on displacement collision events are the PKA energy … more

Permeability Changes in Coal Resulting From Gas Desorption

Description: Eventually, the weight stabilized and the measurements commenced. Helium pressure was increased slowly and carefully, first to 15 psig then to 28 psig. The readout for the balance unit continued to exhibit unexplained fluctuation and output. Buoyancy of the empty pan was measured at pressures ranging up to 800 psig measured at approximately 100 psig increments. The balance weighing unit exhibited a progressive increase in weight with increasing pressure demonstrating that the displacement volum… more

Permeability Changes in Coal Resulting From Gas Desorption

Description: The goal of this task is to accurately measure the elongation and shrinkage exhibited by coal as it sorbs and desorbs methane gas at elevated pressure. Our research group has discussed several possible methods to measure this strain, including: optical microscopy, laser interferometry, conventional strain gauges, and LVDT strain gauges. There are advantages and disadvantages of each method. We had planned to use optical microscopy but, on further investigation, this approach will be less satisf… more

Permeability Changes in Coal Resulting From Gas Desorption

Description: This report documents studies on the effects of gas sorption on coal, with the intent of eventually evaluating how sorption and strain affect permeability. These studies were, carried out at the University of Alabama during the period from 1989 through 1992. Two major experimental methods were developed and used. In the strain experiments, electronic strain gauges were attached to polished blocks of coal in order to measure linear and volumetric swelling due to gas sorption. The effects of bedd… more

Coal-Sand Attrition System and Its' Importance in Fine Coal Cleaning

Description: The product size depicted by the median size and d{sub 90} as well as the corresponding specific energy for the series of tests with silica sand and steel shot respectively are given in Table 3. It is obvious from these results that the products from both systems have a similar degree of fineness. but the silica sand system uses a relatively lower specific energy than the steel shot system. Depending on the experimental conditions, the energy input ratio of the steel and sand media systems vari… more
