Hydrogen Enrichment Impact on Gas Turbine Combustion Characteristics

Effects of Hydrogen Addition, Oxygen Level, and Strain Rate on Combustion Characteristics of CH4/H2 in Staged MILD Combustion

“…The results indicated that the addition of hydrogen enhances the NNH route while concurrently reducing the fast route and N 2 O intermediate route. Mohammad et al [ 15 ] experimentally studied the effect of the volume change of hydrogen concentration from 0 to 25% on the combustion characteristics of gas turbines under fully premixed conditions on the basis of keeping the combustion chamber outlet temperature constant. The results show that H 2 enrichment has minimal or no effect on NO x levels (up to 25% added).…”

“…The results of the second method study show that the lowest CO 2 emission level that can be achieved by on‐board hydrogen production technology through steam methane reforming is 75.17 g CO 2 /kW, which is equivalent to hydrogen‐rich fuel obtained by hydrogen dilution up to 53%. Bassam S. Mohammad et al [ 15 ] studied the effect of hydrogen enrichment on the combustion characteristics of gas turbines, and the percentage of hydrogen enrichment volume varied from 0% to 25%. The results show that the concentration of hydrogen up to 25% has a limited effect on the NO x emission of perfect premixed combustion.…”
