3 Titan 250 Gas Turbine

3.1General Description

The two-shaft Titan 250 gas turbine (Figure 3) is a completely integrated and self- contained prime mover. The Titan 250 gas turbine combines high performance operation with rugged industrial construction. This design philosophy allows for high efficiency, low maintenance, and a long service life. The Titan 250 gas turbine is designed for a high degree of compliance with American Petroleum Institute (API) requirements.

3.1.1Principles of Operation

During the typical combustion process (Figure 4), air is drawn into the gas turbine air inlet and is compressed by the multi-stage, axial-flow engine compressor. The compressed air is directed into the annular combustion chamber at a steady flow. Fuel is injected and mixed with the compressed air and ignited during the start cycle. Continuous combustion will be maintained as long as there is an adequate flow of pressurized air and fuel. Hot- pressurized gas from the combustor expands through and drives the turbine, dropping in pressure and temperature as it exits the turbine. This combustion cycle converts the energy in the fuel into kinetic rotating power at the turbine output shaft.
