The thermal (steam) power plant uses a dual (vapour+ liquid) phase cycle. It is a close cycle to enable the working fluid (water) to be used again and again. The cycle used is Rankine Cycle modified to include superheating of steam, regenerative feed water heating and reheating of steam. Fig. 5: Modified Rankine cycle used in power plant for ...

Bowl mills of slow and medium speed (for both pressurized & suction environment) for coal fired thermal stations with capacity from 10 T /Hr to 120 T/ Hr suitable upto 1000 MW thermal power stations. Ball Tube mills for pulverizing low-grade coal with high ash content from 30 T/ Hr to 110 T/ Hr catering to 110 MW to 500 MW thermal power

1 EIA, an independent arm of the Department of Energy, is the primary public source of energy statistics and forecasts for the United States. The estimated amount of new generating capacity is taken from the Excel output spreadsheet for the Annual Energy Outlook 2008 report. Note that EIA forecasts assume no change to the laws and regulations
