Combustion of H-Coal and EDS (Exxon Donor Solvent) Coal Liquids in a Tangentially Fired Boiler

摘要

The report describes the results of a test burn of approximately 5000 barrels of H-coal, 1200 barrels of EDS, and 1600 barrels of a mixture of the two coal-derived synthetic fuel oils, conducted at Con Edison's 74th St. Station Boiler No. 122, a tangentially-fired, Combustion-Engineering boiler, rated at 450,000 lbs./hr. steam at 1350 psig and 955 deg F. Baseline testing with No. 6 fuel oil was carried out for comparing boiler performance and flue gas emissions with the synthetic fuels. The report documents emission measurements and boiler performance measurements, and discusses problems experienced in synthetic fuel barge unloading and forwarding to the burners. The special industrial hygiene program developed by plant personnel for handling coal-derived synthetic fuels is also documented.
