What should be monitored to prevent hazards in gas turbine systems?

Monitoring various parameters in gas turbine systems is crucial for ensuring safety and efficiency. Each of the listed items—surface temperature, fuel leakage, and airflow rate—plays a significant role in the overall operation and safety of gas turbine systems.

Surface temperature must be closely monitored because elevated temperatures can indicate potential overheating, which may lead to equipment failure or even fires. Keeping track of these temperatures helps maintain the integrity of the turbine components.

Fuel leakage is a critical concern due to the risks it poses. Fuel leaks can lead to hazardous conditions such as fire or explosion. Regular monitoring for any signs of leakage allows for immediate rectification actions to prevent these dangers.

Airflow rate is essential for maintaining optimal combustion and system performance. Insufficient airflow can cause incomplete combustion and increase emissions, while excessive airflow may spoil the fuel-air mix. Monitoring this parameter ensures that the gas turbine operates efficiently within its design parameters.

By monitoring all these factors, a comprehensive safety strategy is developed, leading to the prevention of potential hazards in gas turbine systems. Therefore, the answer that encompasses all these critical areas is the most appropriate choice.
