    The characteristics of the power requirement of a moving bed with mechanical agitation have been investigated. The torque of agitation and pressure drop of the solid-gas moving bed were measured under various experimental conditions.
    The amount of decrease in the torque by the flow-down of solid particles can be characterized by a dimensionless parameter defined by the ratio (F/ρα Vagl) of solid particles flow rate due to the gravity force, F and the convective flow rate by mechanical agitation, ρα Vagi, On the other hand, the amount of decrease in torque due to blowing air in the particles bed has been well interpreted in terms of a dimensionless pressure drop Δp/Δpmf, where Δpmf is the pressure drop at the minimum fluidization velocity, umf.
    The general correlating equation for agitating torque has been provided. The power requirement for the moving bed with mechanical agitation has been well correlated by the various experimental parameters within an accuracy of ±30%.

    The most common problems of discharge electrodes in electrostatic precipitators are associated with failures of mechanical, electrical and chemical factors. We carried out tests utilizing an electro-charged water column for discharge electrodes instead of the wires. This system is applied to both a wet and dry process. In the former process, the electro-charged water column and electro-charged droplets are generated by the application of a high voltage directly to water. Dust particles are collected by electrostatic force and scrubbing. In the latter process, an electro-charged water column is produced to use a straight nozzle and is charged negatively with a 10-30kV power supply. Calcium carbonate is used for the test powder.
    The main results are summarized as follows: (1) Although this system is looked forward to as being a new precipitator type having two features, both electrostatic precipitators and scrubbers in a wet process, it is similiar to the collection mechanism in comparison with the conventional wet type of electrostatic precipitators; (2) In a dry process, the electrical characteristics of an electro-charged water column have advantages over that of wires. This system is achieved to attain the maximum electric power and the maximum field strength without rapping.
    However it is necessary to establish a method of making a water column, about 5m in length. The electro-charged water column in a dry process has been proven advantageous for specific applications.
