The principal purpose of the electrostatic precipitator in the cement industry is prevention of air pollution and collection of valuable materials escaping from the whole processes. Among the various conditions which E.P. performance depends upon, the high resistivity of the particles is the main deteriorating factor. In order to improve the E.P. performance, humidification system that controls the resistivity with moisture is used in general. In this paper, some studies are made on the humidication system using two-fluid nozzles at E.P. inlet as well as on the cause of the E.P. troubles and their counter-measures.

Plane and space movement of an object or section's shape should be indicated by mathematic equations. The error of mathemtic equation is less then the other model. In this paper, general curve X²+C₁Xy+C₂y²+C₃X+C₄Y+C_(5)=0 is chosen to the data which are parabola, circle, ellipse, etc., rotated and translated with respect to the axes. Then LSE method is applied to determine the parameters Ci to transform quardratic curve into standard equation.
