Performing Maintenance on a Gas Turbine at the Coal Research Bureau, Morgantown, W. Va.
Date:
1960-1970
Description:
Coal Research Bureau (Bureau of Mines). Charles N. Resenecker of the Bureau's gas turbine staff checks assembly of the bearing between the turbine and compressor rotors. The large bladed rotor at the left contains the new blades, and is the heart of the gas turbine plant. The air compressor is the bladed unit at the right. Hot high-speed gases from the combustion of coal spin the rotor at the left and then leave through an exhaust stack (not shown). The air compresor, rotated by the turbine, supplies air needed to burn the coal. The turbine also drives electric generators (not shown in this photograph).
