The Difference Between Steam and Gas Turbines

· This water-based cycle is the Rankine Cycle Unlike turbines turbines dont have an air compressor or system but rather a rotors that transfer thermal energy into mechanical energy and a casing area that ensures the contacts the blades under pressure

Natural Gas Fired Boilers

Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion Coal fired boilers normally operate with 3-35% O2 (about 20% excess air) Whereas natural gas boilers normally operate at 1-15% O2 (about 7% excess air)? Steam and exit gas temperatures
