AB  - The low-low temperature electrostatic precipitator (LLT-ESP), a combination of a 
      traditional temperature electrostatic precipitator (ESP) and a non-leakage media 
      gas-gas exchange (MGGH), could reduce the inlet flue gas temperature below the 
      dew point and improved the performance of the ESP. Particulate matter (PM) from 
      the stationary sources contains filterable particulate matter (FPM) and 
      condensable particulate matter (CPM). In this study, coal with a high ash content 
      (coal-HA) was burned, and the emission characteristics and removal efficiencies 
      of the particulate matter in an LLT-ESP were investigated. The standards used to 
      test filterable and condensable PM were ISO standard 23210-2009 and U.S. EPA 
      Method 202, respectively. The LLT-ESP was efficient in removing filterable PM, 
      with a total filterable PM removal efficiency as high as 99.6%. The removal 
      efficiency of filterable PM increased with increasing particulate size and 
      decreasing imported flue gas temperature. The LLT-ESP also provided excellent 
      removal of condensable PM with a condensable PM removal efficiency exceeding 77%. 
      Upstream of the LLT-ESP, the concentrations of filterable PM were much higher 
      than those of condensable PM. Downstream of the LLT-ESP, the relationship between 
      the quantities of condensable and filterable PM reversed. To reduce the emissions 
      of PM from coal-fired power plants, more attention should be paid to controlling 
      condensable PM. The temperature of the flue gas upstream of the LLT-ESP played an 
      important role in eliminating condensable PM. At lower imported flue gas 
      temperature operation conditions, the removal efficiency of the LLT-ESP for the 
      condensable PM and the escaping mass concentration of condensable PM increased. 
      Among the organic fraction of the condensable PM, hydrocarbons and esters were 
      dominant. Meanwhile, SO(4)(2-) was the primary component, followed by Cl(-) in 
      anions. Na(+), Ca(2+), and Fe(3+) were the main components in metal ions. 
      Particles with diameters >/= 10 mum, which contained most of the Si and Al, were 
      dominant in the fly ash collected from sections 1 and 2 of the LLT-ESP. The main 
      particles in sections 3 and 4 were PM(10), which contained the highest 
      concentrations of Ca and Fe.
