Description:
The report gives results of an evaluation of coal cleaning as a means of controlling SO2 emissions from coal-fired stationary sources. Coal cleaning was examined in the light of various existing and proposed SO2 emissions regulations to determine applications in which the technology would be most useful. Barriers were identified that prevent wider application of coal cleaning. Actions are described which should be taken to overcome these barriers. Much information about coal is compiled as resource data on the coal reserve base, present and projected coal production, coal cleanability, current and projected coal use by utilities and industry, size and age distribution of coal-fired facilities, and the nature of coal contracts. Environmental impacts of coal cleaning are compared with those of other sulfur removal strategies such as flue gas desulfurization and the use of low-sulfur coal. Similarly, costs of the various SO2 control alternatives are compared. Cost analyses show an economic superiority for physical coal cleaning generally, even if supplemental application of another method, FGD, must be used to achieve full compliance with NSPS or SIP emission limits.
