Evaluation Test on a Refuse Incinerator at Stanford University Environmental Safety Facility, Stanford, CA

摘要

An evaluation test was conducted to determine the emissions from an Environmental Safety Facility refuse incinerator. The refuse incinerator exhaust gas passes through a sodium hydroxide scrubber, then a natural gas-fired reheater before the gas is vented to the atmosphere. The incinerator was operated at average burn rates of approximately 550, 620, 725, and 805 pounds of refuse per hour on successive days during the test period. Daily average oxygen concentrations ranged from 9.5 percent (%) to 11.5% and the carbon dioxide concentrations ranged from 5.5% to 7.0%. The dioxin emissions from the stack ranged from 0.2 nanograms per second (ng/sec) for tetrachlorodioxin (TCDD) to 4.2 ng/sec for the heptachlorodioxin (HpCDD). Furan emission rates from the stack ranged from 0.5 ng/sec for the tetrachlorofuran (TCDF) to 10.1 ng/sec for the pentachlorofuran (PeCDF). The hydrochloric acid emission rates at the caustic scrubber inlet ranged from 6 to 9 pounds per hour and at the scrubber outlet ranged from 0.006 to 0.034 pounds per hour.
