    • Abstract
  • The installed capacity of coal gangue power plants in China has reached 30 000 MW, mercury pollution from coal gangue power plant can not be ignored. In order to establish and perfect the theoretical basis of mercury control technology, the release law and kinetics of mercury in coal gangue combustion were systematically studied, the results show that the release rate of mercury in coal gangue increases with the increase of combustion temperature and residence time; the law of mercury release conforms to the first-order kinetic equation, the activation energy E of mercury release reaction in 1# gangue and 2# gangue is 25.25 kJ/mol and 18.77 kJ/mol respectively, the frequency factor A is 0.796 min-1 and 0.189 min-1 respectively.
