- Schematic Diagram of Coal-Fired Gas Turbine
- Date:
- ca. 1960-1970
- Description:
- Coal crushed to 3/16-inch by 0 is pumped to a pulverizer that grinds it to 90-per cent hrough 200-mesh. The product is mixed with air and burned in the combustors. Hot high-speed gas from the ash separators drives the turbine, air compressor, and electric generators. Exhaust from the turbine passes through a regenerator that preheats compressed air to the combustors. If used, please credit Bureau of Mines, U.S. Department of the Interior.
