'A small portion of the hot ash-laden gas stream entering the turbine is continuously removed by this ash-sampling unit. Data from the operation of this unit is analyzed to determine the concentration, size, and composition of the ash in the hot gases entering the turbine.'
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.
This mock-up shows the new blade design being tested by the Bureau of Mines. The base of the blade is thicker and there is a strip of titanium carbide at the point of previous severe erosion. If used, please credit Bureau of Mines, U.S. Department of the Interior.During LDC's final 1,100-hour run, this rotor blade (arrow) was undercut by ash flowing along the rotor past the tips of the stator blades.
