Abstract

This paper describes an environmental monitor method. Here we describe a method for measuring the amount of soot and dust discharged from the plant and incinerator. The principle of method is based on the electrostatics. When the soot and dust pass through the strong electric field, these contact to the ionized air and are charged. These induce the change in the electrostatic field near the electrode in the downstream when passing through near it and the small current occurs in the electrode. The current is proportional to the amount of electric charge of the soot and dust, and the amount of soot and dust is proportional to the charge. Thus, the soot and dust amount can be estimated from the current. Here, a mathematical model that relates the current and the mass flow rate of the soot and dust is constructed, and a new measurement method based on the model is presented. The validity of the method is experimentally examined.
