Come stricter.Such as《Fossil-fuel power plant atmospheric pollutant emission standard (GB 13223-2011)》Define the thermal power generation of key area
The flue gas pollutant concentration of emission limit value of factory is：SO2 50mg/m3, NOx100mg/m3, dust 20mg/m3；And National Development and Reform Committee,
Chinese Ministry of Environmental Protection, National Energy Board combined what is printed and distributed in 2014《The energy-saving and emission-reduction of coal electricity upgrade and transformation action plan (2014-2020
Year)》, the flue gas pollutant concentration of emission limit value in the thermal power plant of some areas is entered one and is reduced to：SO2 35mg/m3,
NOx50mg/m3, dust 10mg/m3.In addition, the provincial standard more tightened up than national standard, such as Shanxi have also been put into effect in some provinces
General office of provincial people's government《On promoting the implementation guideline of the whole province's Thermal generation unit minimum discharge》, the firepower of Shanxi Province is sent out
The flue gas pollutant concentration of emission limit value of power plant enters one and is reduced to：SO2 35mg/m3, NOx50mg/m3, dust 5mg/m3.And
And issued according in November, 2016《Control pollutant emission licence system embodiment》, the discharge implementation total amount control of pollutant
System, it is meant that under certain condition, the concentration of emission of pollutant will further decrease.Therefore, skill is administered for atmosphere pollution

It is bigger to rush the change of transformer, typically more than 30, and the no-load voltage ratio of armature winding and secondary windings is big, and system inductance is big, pulse
Forward position is delayed, so that reactor energy injection efficiency is low, energy consumption is big, and high energy consumption seriously constrains pulsed plasma flue gas one
The development of body purification techniques, in the demonstration project of some early stages, power consumption is about the 2% of power plant generated energy, therefore, the skill
Art occurred so far, not realizing large-scale engineer applied from 1986；It is used for gas cleaning in another aspect conventional art
Pulse generating unit voltage waveform in, rising edge is too slow, cause unit of electrical energy produce plasma it is less efficient, so as to
Constrain gas cleaning efficiency, it is impossible to meet increasingly strict flue gas pollutant emission concentration standard.
