It helps ensure you choose the right equipment, spare parts, and maintenance practices for optimal performance. Why Compare Gas Turbine and Steam Turbine Parts? At first glance, both turbines may seem similar\u2014they each have a rotor, casings, bearings, and auxiliary systems. However, their design, operating principles, and parts requirements differ because they rely on different working fluids: Gas turbines use combustion gases generated by burning fuel. Steam turbines use high-pressure steam produced in a boiler. These differences influence the types of parts used, their durability, and their maintenance needs. &nbsp; Key Differences Between Gas Turbine and Steam Turbine Parts 1. Combustion System vs. Boiler Gas Turbines: A significant part of a gas turbine is the combustion system, which mixes fuel (like natural gas or liquid fuel) with compressed air and ignites it. The hot gases expand through turbine blades to produce power. Steam Turbines: Steam turbines do not have a combustion system inside the turbine itself.

Steam Turbines: Bearings in steam turbines must manage large axial loads caused by steam pressure and moisture forces. They often need robust sealing systems to prevent steam leakage.
