ICESP X CONFERENCE PAPER ABSTRACTS 10B SERIES

Held in Cairns, Australia
June 25 - 29, 2006

The International Conference on Electrostatic Precipitation (ICESP) is the official conference of the International Society for Electrostatic Precipitation (ISESP).  

The following is a list of the Abstracts for the 10B Series papers from the X ICESP Conference.  

10B1
DEVELOPMENT OF ELECTROSTATIC PRECIPITATOR
FOR ROAD TUNNEL
KAZUAKI MIYAKE, HIDEKATSU FUJISHIMA, YASUTOSHI UEDA

Abstract

Since Japan has a geographical feature with a lot of mountains, many long tunnels such as exceeding 2 km have been constructed. In the case of long tunnel, problem of insufficient visibility is sometimes caused by large vehicles of diesel engine. To keep driverís visibility, electrostatic precipitator (ESP) has been installed in by-pass tunnel of the main tunnel. Furthermore, not only in mountainous area but also in metropolitan and suburb areas, many tunnels have been constructed to avoid traffic congestion in recent years and ESP has been installed in ventilation tower in order to reduce external emissions as well. ESP installed in ventilation tower is required small installation space and large volume air flow rate.

Based on many experiences and technologies on ESP for industrial applications, we have developed the technology of new (spiked) plate type ESP for road tunnel requirement instead of wire type ESP which is often adopted in earlier ESP for road tunnel or in air purifier installed in air conditioner.

This paper describes the introduction of new (spiked) plate type ESP and its application for road tunnel in Japan. Furthermore, ozone (O3) reduction method using the intermittent energization of high frequency power supply is introduced as well.

10B2 
HIGH VELOCITY ELECTROSTATIC PRECIPITATOR
FOR ROAD TUNNEL
HENDRE D GROBBELAAR

Abstract

The probe of this instrument can be inserted into the flue directly for testing the specific resistivity of fly ash. It adopts the ceramic filtration catcher and iso-speed sampling based on static pressure balance technique with parallel short-tube. The collection efficiency of ceramic filtration catcher (h) can reach even exceed 99.9%, and the error of sampling in different velocities is less than or equal to 5%. All these make the sameness between samples and the actual fly ash in many facets, including size distribution, carbon content, element compositions, etc. The coefficient of optimizing ringed electrode for concentric cirques k is 14.6, which can adapt all kinds of fly ash whose specific resistivity is in the range from 104 to 1013 cm ◊ W . In addition, the ceramic filtration catcher made of white corundum powder can endure high temperature, high voltage, and acid cauterization. So this test instrument can work well under the conditions in which the flue temperature is from room temperature to 300oC and in the caustic gas. Ceramic filtration catcher also has many excellences, such as avoiding disassembly, cleaning ash easily, repeating use for long time. This instrument has obtained the invention patent in China and applied widely in the domestic range.
