ABSTRACT
This chapter provides methods to control specific pollutants. It discusses techniques which specifically control sulfur oxides. The chapter deals with a review of methods which are not specific to any one pollutant but which reduce the damages of air pollution in general. The sulfur dioxide is removed from the boiler along with all the other flue gases and ejected into the atmosphere. Coal beneficiation is a process whereby coal is cleaned before it is shipped away from the mine mouth. The choice of fuels has a critical impact upon potential emissions of sulfur and upon sulfur removal systems. There are a number of ways to control the potential quantity of particulates emitted from a coal fired boiler. One effective method is to use high temperatures and sufficient oxygen for more complete combustion. Electrostatic precipitators attempt to take advantage of the ability of particles to hold a charge.
