008 - Application of Wet Type Electrostatic Precipitator for Boiler Plants

Mitsubishi Heavy Industries, Ltd.

Abstract
Dust emission level is recently required to be more and more severe in advanced industrial countries

In Japan , very low emission level which would realize an almost invisible stack is required especially for new installation of power station near large cities.

In Europe and USA , meanwhile, there are problems of bluish smoke due to SO3 mist.

As the countermeasure, wet type Electrostatic Precipitator (wet type ESP) is applied in Japan .

The application of wet type ESP for boiler plants is described as follows.

021 - Improving Collection of Toxic Fine Particles in ESPs
Norman Plaks
Consultant

Abstract
A modern ESP performance prediction mode, ESPVI 4 0a, is used to evaluate the effect upon penetration of both the submicron and rapping reentrainment fractions from various designs and upgrade approached, submicron particles are the size range in which non volatile toxic materials, when present, mainly reside.  A powerful tool is presented for predicting the reduction in particulate emissions by size fraction prior to an ESP initial design or later upgrade.

027 - An Experimental Study of the Performance of an ESP Operating Downstream From a Semi-Dry Desulphurization Unit

Abstract
Semi-dry desulphurization processes such as spray-drying (S), in duct injection, or circulating fluidized bed are cost-effective retrofit technologies for low to medium capacity coal power plants.  However, it is critical to the technical and economical viability of these FGD technologies that the performance of the existing and probably old ESP, operating under the new conditions, be good enough to maintain emissions levels within legal standards.  This paper collects and discusses data from an SD/ESP pilot plant located at the Los Barrios Power Plant ( Cdiz , Spain ).  A series of tests with two SO2 concentration levels, two flyash load levels, three Ca/S ration levels, and three sulfur removal yields was run in a six-month experimental program.  Particle  load and size distribution, ESP penetration and emissions level, electrical operating point (V-I), and power consumption were measured in order to evaluate the SDs impact on the ESP by means of comparing these measures with those obtained at baseline conditions, i.e., bypassing the SD.  The use of intermittent energization has also been analyzed as a means of reducing power consumption.
