Shortage of natural gas is reviving interest in low-btu fuel gas made by gasifying coal in fixed-bed producers. The Bureau of Mines gasified strongly caking Pittsburgh bed coal over test periods lasting 4 days in an experimental gas producer located at Morgantown, West Virginia. Mechanical stirring throughout the fuel bed was effective for keeping the fuel moving and this stirring made the operation successful; hence, the gas producer was named the stirred- bed producer. Nuclear density gages were applied as control instruments to indicate coal flow and fuel level and to record the frequency and location of void spaces in the bed. The gas, of nominal 140 to 165 btu scf calorific value, could be burned in a boiler for generating steam.
