Therefore, injection of sorbent, and possibly water for humidification, will most often be performed downstream of the air preheater and upstream of the electrostatic precipitator, where the gas temperature is typically in the range of 280-300 eF.
The gas temperature upstream of the electrostatic precipitator is in the range of 280-300 degrees F.
The information on the three documents had to be of sufficient detail to allow an effective comparison to occur.
