Jan 15, 2019 Thermal Power Plants contribute maximum to the generation of Power for any country. Thermal Power Plants constitute 75.43 of the total installed captive and non-captive power generation. In thermal generating stations coal, oil, natural gas etc. are employed as primary sources of energy.
Proper design and operation of the pulverized coal burners protects the pulverizing system from ignition from the furnace fire. The coal air mixture enters the furnace through a burner nozzle at velocities in excess of the flame speed. Thus, the flame front is held stable at a distance away from the end of the nozzle where
