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.
The open cycle exausts the gases (produced by combustion) directly to atmosphere, sometimes the heat can be reclaimed to be utilised in a combined system (Rankine cycle added to gas cycle). Where as the closed cycle will reuse the gasses from the exaust instead.
Depends on what type of gas, plant size and cycle and carriage.
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.

A semi-closed cycle is a closed cycle which incorporates internal combustion with controlled removal of excess carbon dioxide and water, and controlled addition of a corresponding amount of fuel and oxygen as dictated by the power generation needs. Use of air instead of oxygen is would create a build-up of nitrogen in the working fluid, and increase NOx pollutants. Recirculation of some of the carbon dioxide closes the cycle.
A gas turbine is one type of power plant. It produces power by burning gas to turn the turbine.

yes, it is a heat engine. A heat engine is one that extracts heat energy and converts it to mechanical energy.

gas turbine are used for expansion of high pressure gas,which rotates the rotor coupled with generator and hence electricity is finally produced.Gas turbine operate on brayton cycle.
You can use the bio gas to fuel either a steam cycle generator or a gas turbine.

Gas turbine engines and airbreathing jet engines use the Brayton Cycle.
