Abstract: In gas turbine second stage stationary blade, cooling air passage of inner shroud is improved so as to obtain enhanced cooling efficiency.       In inner shroud 126, there are provided leading edge passage 42 and trailing edge passage 44, both extending from blade portion and mutually separated by rib 40, and impingement plates 83, 84 having multiplicity of small holes 101.  Opening portion 68 between the blade portion and the inner shroud 126 is closed by bottom plate 150 and, together with recess portion 100 at bottom portion of the leading edge passage 42, connects to passage 188 of leading edge portion 41 via passage 90'.  Air from the trailing edge passage 44 flows into cavity 45 to be injected through the small holes 101 of the impingement plates 83, 84 for cooling of central portion of the inner shroud 126 and then is discharged as air 60 through passages 92 of the trailing edge portion 43.          Entire amount of the air from the leading edge passage 42 enters the passage 188 to be enhanced of heat transfer effect by turbulators 200 and further flows separatedly into passages 93, 94 of side edge portions for cooling therearound to be then discharged as air 61.  Air amount in the leading edge portion 41 and the side edge portions are increased and cooling effect is enhanced.

Title: Removing hydrogen sulfide from a gaseous mixture using iron hydroxide bonded to calcined diatomite
Inventor: MCMULLIN MICHAEL J
IPC: B01D53/04
Filed: 2001-02-07
Granted: 2004-03-30
Abstract: A process for removing hydrogen sulfide from a gas stream wherein the filtering media consists essentially of calcined diatomite and between 5% and 30% by weight of ferric ions bonded to the calcined diatomite. This process is particularly efficient due to the fact that the removal of hydrogen sulfide from the gas stream is effected with a single pass adsorption performance of up to 45 mg of H2S per gram of filtering media. Other advantages include the fact that the process has the ability to remove H2S form a gaseous mixture, from a concentration of 30,000 ppm down to non-detectable levels in a single pass. Repeated in-situ regeneration of the filtering media has been proven to be a simple matter of blowing ambient air through the filtering media.
