J.P. McGee, Acting Research Director, and Jack Smith, in Charge of the Gas Turbine Development Project discuss proper positioning of the turbine rotor in its casing.

1. Proper Positioning of the Turbine Rotor in Its Casing

IDNO:
002648
Title:
Proper Positioning of the Turbine Rotor in Its Casing
Date:
1960-1970
Description:
J.P. McGee, Acting Research Director, and Jack Smith, in Charge of the Gas Turbine Development Project discuss proper positioning of the turbine rotor in its casing.
'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.'

2. Sampling Hot Ash-Laden Gas

IDNO:
002686
Title:
Sampling Hot Ash-Laden Gas
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.
