The use of Exxon Donor Solvent (EDS) as a utility boiler fuel was evaluated at Southern California Edison Company's Highgrove Unit 4, a Combustion Engineering 44.5 net Mw wall-fired boiler. The EDS evaluated was a full range solvent oil produced at the Exxon Coal-Liquefaction Pilot Plant in Baytown, Texas. This evaluation involved modifying the boiler equipment and operating procedures for EDS, and then firing 4500 barrels of EDS in the boiler. The resulting boiler performance and emissions with EDS were compared to those with a blended low-sulfur petroleum distillate similar to No. 4 fuel oil and with natural gas. The boiler was operated over a range of load and excess air conditions during the tests. The potential for NO/sub x/ reduction with a burner out of service (BOOS) was also evaluated. Boiler performance, including excess air requirements, maximum load, thermal efficiency and heat rate efficiency was similar to that with oil. The NO/sub x/ emissions with EDS were about 12 percent higher than with oil. NO/sub x/ reduction with BOOS was about 20 percent with both oil and EDS. EDS use did not result in an increase in particulate emissions. Submicron particulate, however, was increased with EDS. Required equipment modifications at Highgrove primarily involved material compatibility with EDS, fuel system capacity, and the burner nozzles. The use of EDS required the implementation of health and safety procedures due to the adverse health effects that could result from prolonged exposure to the fuel. The results of the evaluation demostrated that EDS can be used in a utility boiler designed for oil with only minor modifications.
