• GTI will substantially reduce gas turbine unabated NOx levels.

• Steam is injected into the combustors and power turbine to increase the mass flow, which then results in increased power output.
• The steam also provides a thermal heat sink in the combustor that lowers the temprature reducing the creation of thermal NOx.

• El vapor se inyecta en las cámaras de combustión y en la turbina de potencia para incrementar el flujo másico, lo cual produce una mayor potencia de salida.
• Además, el vapor proporciona un disipador térmico en la cámara de combustión que baja la temperatura y disminuye la producción de NOx térmico.

• The application of steam injection can occur at various injection levels. In general, at levels less than 5%, wear and tear on the turbine is negligable.
• Additionally, any increased maintenance that is required is greatly over shadowed by the increase in net power and the reduction in fuel use.

• La aplicación de la inyección de vapor puede producirse en varios niveles. En general, en niveles menores al 5%, el desgaste de la turbina es mínimo.
• Además, cualquier mantenimiento mayor que se necesite pierde su importancia ante el incremento de la potencia neta y la disminución en el uso de combustible.

• Each gas turbine will require a unique amount of water supply based on the steam injection rate.
• For the Frame 7FA, with an air mass flow = 3,381,000 lbs/hr and based on 5% steam injection:The amount of water required is: 3,381,000 lbs/hr x .05 = 169,050 lbs/hr steam = 169,050 lbs/hr water
• This equates to 337.5 GPM.

• Cada turbina de gas necesita una cantidad de agua diferente según la proporción de la inyección de vapor.
• Para el armazón 7FA, con un flujo másico de aire = 3,381,000 lbs/hr y con una inyección de vapor de 5%:  la cantidad de agua que se necesita es: 3,381,000 lbs/hr x .05 = 169,050 lbs/hr de vapor= 169,050 lbs/hr de agua
• Esto equivale a 337.5 GPM.

• Water injection is in principal like steam injection however, it is not as efficient for power augmentation or NOx control.
• Water when it is injected into the GT combustor absorbs more heat energy than steam. The resulting loss of energy robs power from the GT thus making it less efficient.

• En principio, la inyección de agua es similar a la inyección de vapor. Sin embargo no resulta tan eficaz en cuanto al incremento de la potencia o al control de NOx.
• Cuando el agua se inyecta en la cámara de combustión de la turbina de gas, absorbe más energía térmica que el vapor. La pérdida de energía resultante le quita potencia a la turbina de gas y, por lo tanto, hace que sea menos eficaz.
