Which gas turbine is the best for my combined cycle power plant conversion?




The objective of this experiment is to discover the gas turbine important to handle 58 MW of aggregate net force for the transformation of a steam turbine to a joined gas-steam cycle while giving the largest amount of cycle warm effectiveness.


The fumes gasses from the gas turbine are utilized to hotness up steam through three Hrsgs (Heat Recovery Steam Generators) in arrangement. The steam is then utilized as a part of the concentrated on steam turbine which is involved two "chambers" in arrangement.

The main hotness exchanger gives the steam conditions for the turbine delta.
The second HRSG is utilized between the two barrels, as an incitement, to expand the mass stream experiencing the last chamber and additionally to superheat the liquid to guarantee proper liquid quality before the condenser, subsequently boosting turbine dependability.

At long last, the third high temperature exchange goes about as a middle of the road before the first recuperator. Along  these  lines the steam entering it is as of now preheated and the steam temperature leaving the second heater might be higher, subsequently giving additional enthalpy to the stream after the blending.

The gas turbines picked for this experiment were chosen focused around their hotness rate, deplete temperature and mass stream and generated force around the library components inserted inside Axcycle™. The effects of this experiment are displayed in the table underneath.

From the outcomes displayed one can see that the cycles with the GE 6581b, the Siemens SGT-900 Westinghouse 251 B10a and B12 and also the Alstom Gt8 are the main ones that meet the obliged net force creation of 58 MW. The cycles offering the B12 and the Gt8 produce noteworthy additional power because of the bigger limit and this suggests that the gas turbine value and expense of operation will be expanded past essential. We are then left with the other two cycles, the unified with the GE 6581b which gives the most note worthy consolidated cycle warm proficiency because of its high fumes gas temperature and mass stream rate and the one offering the B10a which falls just quickly behind.
