if u have worked on a power plant , could you tell me
1- efficiency of a gas power plant in single mode.
2- efficeincy of a furnace oil runpower plant in combined cycle mode .
3- Efficiency of a furnace oil run plant on single mode .
4- Efficency and diesel consmption per kwthr in a power plant in combined cycle mode .
Nandi pur is no 2 type , if you know ,you will come to know the answer of your all questions and also that it is not possible produce a unit at Rs 40 kwthr.
I am not questioning the pricing my question is the intent of installing a CCGT plant, the price of fuel has a direct impact on cost of electricity. The fuel prices have been through the roof for the past year they have only crashed in the last few months, had it not been then it was clearly as obvious as you don't buy a car that runs on aviation fuels.
Clearly there are a few points that I would like to mention, CC plants are highly efficient. The Latest GE CCGT Series offer upto 54% (Electrical efficiency) . (Yes They mention 60% plus in their catalogs, that is if you take distirict heating in the scheme of things, In variably the Thermodynamic efficiency). Now, These are absolute Laboratory condition efficiency I am talking about.
1. Now, a Fuel oil CC plant is a CCGT plant which is essentially has a fuel oil gassification Unit and which allows the GT to function and hence multi mode fuels are used. gassification is an energy intensive process. So that will take down your efficiency *consume more auxiliary power*.
2. the Absolute Lab conditions are where intake air is dry and low temp all year round. Hot and humid air intake will significantly dent the plant (gas turbine) efficiency. Hence you see these types of plants usually cold countries of Europe and China and USA (The regions where you have warm summers and cold winters). It will have devastating Efficiency and huge costs if they are utilized as base load plants in Tropical countries, they can be good for commercial peak load plant, where electricity pricing in the grid is dynamic.
So it was a bad choice for a plant in the first place. Should have used a low cost fuel High temperature, [example Łagisza power plant, Poland its still in Tech Demonstartion stage but its becoming proven with each passing day] (super/ultra critical units) and the more number of days the plant is shut, costs increase without return.
so in essence you may have an advantage of 9-10% in power output but your costs are up by 70-80% not much of a difficult choice to make there.
