2 What is IGCC Power Plant?  In IGCC power plants, the coal is not burnt in a conventional steam power plant,butisinitiallydriedandsuppliedtoaGasifier,inwhichhigh temperatures prevail. Here, the dried coal is subjected to pressure and is converted into combustible or reactive gas using air or pure oxygen.

3 How it works?  IGCCusesacoalgasificationsystemtoconvertcoalinto asynthesisgas (syngas) and produce steam. The hot syngas is processed to remove sulfur compounds, mercury and particulate matter before it is used to fuel a combustion turbine generator, which produces electricity. The heat in the exhaust gases from the combustion turbine is recovered to generate additional steam. This steam, along with that from the syngas process, then drives a steam turbine generator to produce additional electricity.

6 Theplant includes….  Coal preparation  Air separation  Coal gasification  Ash removal  Syngas cooling  Acid gas removal  Sulphur gas recovery

7 Benefits  High combined cycle power plant efficiencies.  Modular IGCC concepts to enable phased construction.  Less use of water than conventional coal based power plant.  Easy separation of CO2.

8 Drawbacks  High capital cost  More components, more heat exchangers increase maintenance costs and outage times.  The start up times of IGCC will be more than Pulverized Coal fired power plant due to the large number of sub systems. This makes the IGCC suitable only for base load operation.

9 Some IGCC Power Plant across the globe  Polk Power Station in Tampa, FloridaTampa, Florida  Wabash River Power Station in West Terre Haute, IndianaWest Terre Haute, Indiana  Pinon Pine in Reno, NevadaReno, Nevada  In India there is no IGCC power plant.
