Abstract
A simple process model was used to study the effects certain variables had on the product gas composition from a subbituminous, steeply dipping underground coal gasification field test. The authors found that two key model input parameters were (1) heat loss and (2) the ratio CO/CO/sub 2/ in the carbon oxidation equation. An increase in the heat loss parameter was generally accompanied by a decrease in the CO/CO/sub 2/ parameter in order to fit the field test data. The heat loss parameter increased as the field test progressed, suggesting increased rock fall or ground water influx. Very late in the field test, the only way to fit the data was by substituting a ''fictional'' coal having a high char/volatile ratio. The authors conclude that as the process module aged, the production of char (relative to volatiles) increased.
