Multi-Nozzle Quiet Combustors (MNQC) and single nozzle diffusion combustors provide the capability to some gas turbines to burn liquid fuels and gases with high CO2, CO or H2 content. In the case of these systems, water and steam are often injected into the combustor as a means of reducing/controlling emissions levels. However, it should also be noted that water or steam injection can also be used as a means of gas turbine power augmentation. Table 3 illustrates a classification of the main alternative fuels and their “parent” primary energy sector: oil, gas, coal, residual and renewable, accessible to gas turbines Gas Turbine Exhaust Heat Recovery The economics of.
