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.
Depends on what type of gas, plant size and cycle and carriage.

convection currents r a cycle of heat in the mantle. the energy is produced by the heat in the core. the heat rises it becomes cooler and has a greater density. when the desity starts to decrease, it gets hotter and goes round and round in the cycle for many years. but, when the heat is on the top and it rises, the mantle can open up and cause sea floor spreading to occur.
Check the engine thermostat. Its probably stuck open.
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.
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.
If the thermostat is stuck open, the radiator is able to cool the antifreeze faster than the engine can heat it.
Overheating if stuck closed, no engine heat if stuck open.
