6 FAQs about [The temperature of the air inlet at the generator excitation end is high]

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.

What is a primary turbine inlet temperature?

The primary turbine inlet temperature is 1800 K. The gas enters an adiabatic, reversible secondary turbine that produces net power. The turbine exhaust enters a heat exchanger (HEX) , the heat from which is used for space heating an interior space maintained at the dead state temperature in a cogeneration application.

How to investigate the heat transfer law of a turbine generator?

To investigate the heat transfer law of the studied turbine generator, it is necessary to analyze the temperature distributions, expecially the heat transfer of the air-gap. 1. Temperature distribution in the axial cross section of the turbine generator

What is a gas turbine inlet temperature control system?

These systems include methods for intake heating under low loads and intake cooling under basic loads, which can be used to change the intake temperature of the compressor under a variety of operational conditions. The heat exchanger of gas turbine inlet temperature control system is a key equipment.

What happens if inlet temperature regulation is not taken?

Moreover, if inlet temperature regulation measures are not taken, severe deviation of the airflow angle of the compressor blades may cause surges, overstressing the gas turbine. This, in turn, could severely affect the safe operation of the power plant.

What is a special heat exchanger for inlet gas temperature control?

The special heat exchanger for inlet gas temperature control of gas turbine has the characteristics of large span, windward surface and high position layout. So, the selection and design of heat exchanger have special and stricter requirements [14, 15].
