Energy (Coal Reserves of Pakistan)

The hot gases and heat energy produced converts water – in tubes lining the boiler – into steam. The high pressure steam is passed into a turbine containing thousands of propeller-like blades. The steampushes these blades causing the turbine shaft to rotate at high speed.

Effect of operating parameters on coal gasification

Coal combustion and gasification are the processes to utilize coal for production of electricity and many other applications. Global energy demand is increasing day by day. Coal is an abundant source of energy but not a reliable source as it results into high CO2 emissions. Energy industries are expected to decrease the CO2 emission to prevent global warming. Coal gasification is a process
