Jones, J R

A series of three extended trial burns, each of three days duration, have been completed at the test cement plant under Phase II of the project. One thousand three hundred thirty-eight tons of refuse-derived fuel have been burned to produce approximately 8,500 tons (or 46,750 barrels) of cement. Fuel savings during the three trial burns totaled over 12 million cubic feet of natural gas. Overall quality of the cement produced is good with some loss of strength noted during the 40% RDF burn. This loss of strength may be attributable to operation of the kiln at lower than normal temperature during the third trial burn -- temporary conditions that were allowed to happen inadvertently due to a malfunction in the chart recorder that indicates kiln temperature. This particular recorder is relied upon by the kiln operator to help maintain stable conditions in the kiln. Results of sampling indicate an increase in the levels of particulate emissions when co-firing RDF with gas -- as much as a 5096. increase in emission when firing 40% RDF. Nevertheless, total particulate emissions at 40% RDF are still within acceptable limits on the basis of the EPA's New Source Performance Standards.
