yes, it is a heat engine. A heat engine is one that extracts heat energy and converts it to mechanical energy.
In an open cycle gas turbine, the gases that are produced by combustion go directly into the atmosphere, though the heat produced can sometimes be reclaimed. In a closed cycle gas turbine, the gases produced are reused and are not emitted into the atmosphere.

1. The working gas is compressed in compressor and directed towards the heat exchanger (Air heater), where heat is being added to the compressed gas before it enters the turbine. 2. The heat is supplied by an external source such as a nuclear reactor, or some other heat source. 3. The hot gasses then expend and accelerate through a nozzle which drive the guide vanes of the turbine and then shaft. 4. At last, the remaining exhaust gasses pass through a cooler and directed towards the compressor inlet.
Brayton cycle: It is open cycle. Rankine cycle: It's close cycle. Brayton cycle: Mostly used in gas turbine engine. Rankine cycle: Mostly used in power generation plant. Brayton cycle: Resemble less to Carnot cycle. Rankine cycle: Resemble is more to Carnot cycle.
An open cycle gas turbine (OCGT) is a type of gas turbine that converts fuel energy into mechanical energy through a continuous process. In this system, air is drawn in, compressed, mixed with fuel, and combusted, generating high-temperature exhaust gases that drive a turbine. The exhaust gases are then released into the atmosphere, making the cycle "open." OCGTs are often used for peaking power plants due to their quick startup times and ability to meet fluctuating energy demands.
Depends on what type of gas, plant size and cycle and carriage.

Check the engine thermostat. Its probably stuck open.
In Boiler follow turbine mode , Boiler produces a constant pressure behind throttling valve and throttling valve adjusts necessary pressure and required steam as High Pressure steam for entering the turbine . In Valves Wide Open (VWO) mode the efficiency is maximum and we haven't any loss. (It's nearly 106% Turbine MCR) . In Turbine MCR , we have a little loss and consequently a little bit worse heat rate . In partial load , loss is more and efficiency worse.
Check to see that the heat control is working, and water is flowing through the heater core. Make sure that the engine thermostat is not stuck open, and the engine coolant is full.
Overheating if stuck closed, no engine heat if stuck open.
If the thermostat is stuck open, the radiator is able to cool the antifreeze faster than the engine can heat it.
