DEVELOPMENT PROGRAM FOR AN IONIZER PRECIPITATOR FINE PARTICLE DUST COLLECTION SYSTEM AS APPLIED TO COAL-FIRED UTILITY STEAM GENERATORS Volume II

摘要

This work was directed at developing more effective electrostatic precipitation of fine particulate, particularly of high resistivity fly ash, by imposing a higher degree of charge on the particles. A unique electrode assembly results in an intensely ionized flue gas which leads to a particle charge as high as four times greater than is currently being achieved. Such an ionizer would be the first or charging stage of an improved two-stage power station electrostatic precipitator immunized against high resistivity dust.nGenerally, laboratory analyses and testing have provided the data necessary to proceed with the design of a larger scale field pilot. Economic evaluations of the concept based on laboratory data are included. The evaluations indicate potential cost savings on new systems' and retrofit upgrades.
