ABSTRACT

In order to decrease air pollution caused by coal combustion and increase its utilization as an alternative to oil, coal must be burned in an environmentally clean and economical manner. This chapter explains the measurement of the collection efficiency of calcium magnesium acetate and calcium magnesium carbonate ash to fine particles and the effect of chemical engineering parameters on the collection efficiency. Ferrous sulphate particles were used to simulate very fine air toxin particles. The chapter presents a brief review of air pollution caused by coal combustion, the various methods of capturing fine particles, and the physical mechanisms for particle removal. filter. The most common approach in determining the collection mechanisms is focused on a single fibre. There are three basic mechanisms to describe the deposition of aerosol particles on a fibre: diffusion (Brownian motion), interception and inertial impaction. The ferrous sulphate particle size was measured directly from scanning electron micrographs.
