Air Pollutant Control Techniques for Crushed and Broken Stone Industry

摘要

Air pollutant control technologies for the control of particulate emissions from crushed and broken stone production facilities are evaluated. Specific control technologies considered include the use of local ventilation followed by fabric filter collection and wet dust suppression techniques. Performance data based on mass particulate measurements and visual observations are presented. In addition, the capital and annualized emission control costs for several model plant sizes are estimated. The environmental and energy impacts associated with each control technology evaluated are also presented. Alternative regulatory options available are identified and evaluated in terms of their enforceability, impact on the environment, cost and impact on energy.
