Abstract:
The gaseous and particulate emissions from 14 cutters and boats in the First Coast Guard District have been measured under typical operating conditions. These measurements were performed on 57 diesel engines and boilers configured as main propulsion units, ship-service generators and hotel-service boilers. The diesel engines varied in size from two-cylinder, naturally aspirated, 35 h.p. units to 3600 h.p. turbo-charged units. The gaseous emission concentrations measured were carbon monoxide, carbon dioxide, total hydrocarbons, and oxides of nitrogen. Particulate emission rates by gravimetric technique as well as smoke levels were also documented. These measured concentrations were reduced to mass emission notes by appropriate computer programs.
