Development of 1500ﾟC Class Gas Turbine Combustor for IGCC.1st Report:Design Study and Combustion Test of a Combustor.

概要 （図表や脚注は「報告書全文」に掲載しております）

概要 （英文）

Gas turbine power-generation systems operating on 1500ﾟC firing temperature have higher fuel-to-electricity efficiencies than any other commercially available technology.Less cooling air and higher emissions would be expected under the condition of 1500ﾟC-class gas turbine.Combustion test is conducted using low-Btu coal gases with 1300ﾟC-designed combustor and several technical problems are clarified.As a result,combustor liner temperature is kept almost constantly below permissible temperature.More COand NOx are exhausted owing to fuel-rich condition in combustion chamber.There are two basic problems associated with the use of low-Btu coal gases at 1500ﾟC design point:low fuel-NOx combustion technology by optimization of air distribution and advanced liner composite with higher cooling efficiency.
