Take the following as truth: 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.
Then the following statement: "The gas temperature upstream of the electrostatic precipitator is in the range of 280-300 degrees F." is true, false, or inconclusive?
