Gas turbine firing temperature is the temperature at which the fuel and air mixture is ignited and burned in a gas turbine engine. This temperature is typically between 1500°C and 2000°C.
Gas turbine firing temperature is important because it directly affects the efficiency and power output of the gas turbine. A higher firing temperature can lead to higher efficiency and power, but it also puts more stress on the engine components and can reduce the lifespan of the engine.
Gas turbine firing temperature is controlled through a combination of fuel flow rate, air flow rate, and the design of the combustion chamber. Modern gas turbines also use advanced technologies such as variable inlet guide vanes and active clearance control to optimize firing temperature.
Factors that can affect gas turbine firing temperature include ambient temperature, humidity, compressor efficiency, and fuel quality. Changes in these factors can impact the amount of heat energy produced during combustion, and therefore affect the firing temperature.
High gas turbine firing temperature can result in increased NOx emissions, which contribute to air pollution. It can also lead to higher maintenance and repair costs due to the increased stress on engine components. In extreme cases, it can even cause engine failure, resulting in costly downtime and potential safety hazards.
