6 FAQs about [Generator inlet air temperature is low]
Can Inlet air temperature improve gas turbine efficiency?
The results show that an increase in inlet air temperature has considerable potential for improving gas turbine efficiency due to the increase in compressor and turbine efficiency. This finding is different from traditional viewpoints. Meanwhile, each partial load has an optimum heating temperature which becomes higher when the load is lower.
Does inlet air heating affect gas turbine efficiency under partial load?
A novel heating technology is presented to analyze the influence of inlet air heating on gas turbine efficiency under partial load. This technology uses the waste heat of a low-temperature heat sources, which includes but is not limited to the exhaust gas of a combined-cycle heat-recovery steam generator or a single-cycle gas turbine.
What are the requirements for a gas turbine inlet temperature regulator?
The gas turbine inlet temperature regulator has strict requirements for the resistance of the air flow outside the tube. Generally, the operating resistance is required to be controlled below 150 Pa, which requires that the air flow speed should not be too high.
Does changing turbine inlet temperature increase net power?
For this purpose, based on the energy, exergy, environmental, and economic (4E) analyses, the effects of changing turbine inlet temperature (TIT) on a gas turbine power plant in northeastern Iran were studied. The results showed that increasing TIT enhanced net power and efficiency, so that increasing TIT about 10 K enhanced net power by 1.7%.
Can Inlet air cooling improve the performance of intercooled gas turbine power plants?
In hot climates, the entry of high-temperature air into the compressor of intercooled gas turbine power plants (IcGTCC) can lead to reduced electricity production during peak demand periods. To address this issue, this study proposes a novel inlet air cooling (IAC) system for improving the performance of IcGTCC in hot regions.
Can a novel inlet air cooling system increase power output?
A novel inlet air cooling system for intercooled gas turbines is proposed. The proposed system is able to increase power output by 19% and efficiency by 2.3%. The novel system offers 8–18% better efficiency than existing designs in literature. The new system generates substantial annual profits.
