Description

Fuel nozzles play a highly significant role in the gas turbines. They act like the gateways from where the gas enters the gas turbine. They are typically positioned in the combustor around its circumference. The primary purpose is to atomize the incoming gas in a controlled and uniform manner. The liquid fuel is not pumped into the combustor all at once; instead, the nozzles break it down into a fine mist of tiny droplets through atomization.

Additionally, the design of nozzles is vital for optimal engine performance, which increases the fuel surface area. It allows the compressed air and the fuel to mix more efficiently within the combustor. This mixing is essential for the complete combustion and minimizes the formation of pollutants like soot. For this purpose, some gas turbines are designed to reduce emissions, which is further contributed by the fuel nozzles with multiple outlets for efficient fuel delivery.

Moreover, the nozzle is exposed to high temperatures, which means the combustion process can be harsh on them. It requires the nozzle to be manufactured of high-temperature resistant materials that can withstand extreme conditions. However, regular maintenance and cleaning of nozzles are crucial for the proper functioning and delivering optimal fuel atomization. Otherwise, clogged or malfunctioning nozzles can lead to inefficient combustion, reduced engine performance, and increased emissions. So, ensure the controlled and efficient fuel delivery through proper atomization, promoting clean and efficient combustion for optimal engine performance.
