Emission Factors from Burning Agricultural Wastes Collected in California.

摘要

This project determined the pollutant emission factors from burning 31 field, vine and orchard crops and weeds in an out-of-doors, instrumented burning tower. Carbon monoxide, hydrocarbons, weight and size distribution of smoke particles were determined. Field crops and weeds produced considerably more of all three pollutants than did orchard and vine crops. Back firing field crops resulted in lower emissions of particulates when compared with head firing but this was not so for carbon monoxide or hydrocarbons. Rolling orchard fuel on to existing fires significantly increased emissions in most cases. Most particles from all fires were submicron in size. Back firing produces significantly smaller particles than did head firing. Additionally drying orchard fuels had no real effect on particle size but the roll-on orchard fires produced significantly larger particles than the first fire of the pair.
