Emissions and Control Technology (pages 1-40).
NIOSH 1978 Feb:1-40
Emissions and control technology for diesel equipment used in underground mines is discussed based on engine types, duty cycles, fuel additives, maintenance, engine size, fuel, emission control, inlet air to the engine, emission characterization, and the potential for future engines. Recommendations for further study call for evaluations of exposure and health effects for emission characterization; comparisons of engine types and of emissions typified by extensive adverse health effects; collection of mining duty cycle information to determine relationships to existing emission data; compilations and performance of field research on environmental effects on the inlet air of diesel engines; acquisition of data on engine maintenance; development of a combined emission control system, comprising advanced catalyst, water scrubber, and particulate filtration technology; and investigations of methods for reducing fuel sulfur to the lowest practical minimum. It also is recommended that smoke suppressant additives be eliminated because of their negative effect on engine life and their influence on exhaust particulate emissions; fuel characteristics be studied; further research be concentrated on developing combined devices for emission control; and comprehensive analysis of diesel applications be conducted.
