The application of high-energy physical field

as well as medium-and-low energy physical fields

in coal-fired flue gas desulphurization and denitrification has been summarized up.The high-energy physical fields

such as the high-energy radiation chemical method

the micro-wave induced plasma method

the micro-wave discharging method

and micro-wave heating method etc.

are commonly used for directly changing the reaction mechanism in desulphurization and denitrification

however

the medium-and-low energy physical fields

including the electrostatic sprayer method

the charge drying sprayer method

the magnetic fixed bed method

the magnetically fluidized bed method

the low-temperature iron-base SCR denitrification technology

and the micro-wave induced catalystic reduction desulphurization and denitrification technology etc.

are commonly used for changing the physical process of desulphurization and denitrification.Along with the modification of physical process

the efficiency of flue gas desulphurization and denitrification can be further enchanced.
