Operators of coalfired power plants seek ways to increase the efficiency and extend the working lives of their plants by improving the operational flexibility and reducing the environmental impact. two possible options are explored combining solar energy with coalfired power generation, and cofiring natural gas in coalfired power plants.
Mhps has a strong track record in coalfired ultrasupercriticalpressure thermal power plants. such plants are capable of achieving the worlds highest level of thermal efficiency in coalfired power generation by applying high temperatures and high pressure to steam, while at the same time enabling reductions in co 2 emissions.
The 250mw barapukuria thermal power plant in dinajpur is the only operational governmentowned coalbased power plant being run by the power development board pdb, where the barapukuria coal mining company limited supplies coal. pdb has recently started commissioning of the third unit 275mw of the plant.
