Document Type and Number:
Japanese Patent JP2015102266
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas turbine combustor capable of maintaining high combustion reliability and suppressing NOx emission even if a composition and a calorific value of fuel containing hydrogen change in a wide range using combustion air having a high moisture content.SOLUTION: A gas turbine combustor of the present invention is a gas turbine combustor 3 mixing moisture to combustion air, mixing a mixture of the combustion air and the moisture with fuel containing hydrogen and firing a resultant mixture which includes a plurality of moisture injectors 28 and 29 injecting moisture 15 into the combustion air to be supplied to this gas turbine combustor 3, so that the ratios of the moisture injected from the moisture injectors 28 and 29 into upstream combustion air and downstream combustion air in a combustion chamber, respectively are regulated depending on an operating state of a gas turbine plant including the gas turbine combustor 3.
