The Collection of Silica Fume with an Electrostatic Precipitator

Combination of Electrospray with Electrostatic Precipitator for Collection Efficiency Enhancement of Fine Particles

Electrospray was employed upstream of an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with a size range from several tens to several hundreds μm. The visible combined effect of the ESP with the electrospray was found for the collection of particles larger than about 20...

Power Electronic Modelling and Emulation of an Electrostatic Precipitator

In this paper a power electronic emulation of an electrostatic precipitator is presented. Precipitator power supplies can be tested under real power and operating conditions up to 200 kVA. Energy consumption of the system is very low, because the energy which is drawn by the emulation converter is fed back into the power grid. Therefore, just the power losses have to be provided by the grid. It...

Removal of Serratia marcescens aerosols using an electrostatic precipitator.

We characterized the efficacy of an electrostatic precipitator (ESP) air-cleaner in reducing the concentration of Serratia marcescens in an enclosed space. We used an experimental room (4.5 x 3 x 2.9 m) in which electrostatic aircleaners were located. Two air-cleaners enhanced the equivalent ventilation rates in the chamber by about 3.3 air changes per hour (ACH) over the 2 ACH provided by the ...

Modern High-Voltage Control of an Electrostatic Precipitator

Improving the workability and strength of silica fume concrete by using silane-treated silica fume

Mortar with high workability even without a water-reducing agent and with high tensile and compressive strengths (3.1 and 78 MPa, respectively) was obtained by using as an admixture silica fume that had been surface treated with a silane coupling agent. The treatment enhanced the wettability of silica fume by water, thereby increasing the workability of the mortar mix. It also enhanced the bond...
