Technology Solutions and Effect of Boiler Changes Burning Datong Bituminous Coal
Based on 4×325 MW units have been used for more than 20 years,the boiler＇s aging has caused the decline of efficiency.And also because of the difficulties of purchasing original designed meager-lean coal,power plant decided to change meager-lean coal to Datong bituminous coal,in order to extend the range of coal and improve the efficiency and reliability of the boiler.Through the reform of coal pulverizing system,burner system and local heating surface,power supply coal consumption and NOx emissions decreased significantly.By now,the reform of 4 units has been accomplished,the effect of energy-saving and emission-reduction is very obvious.
