Assessment of Needs for Environmental Controls for Burning a Coal-Oil Mixture in a Slot Forge Furnace

摘要

An environmental study was completed on the use of a 56% powdered coal - 44% fuel oil slurry as fuel in an experimental slot forge furnace designed by Hague International. Measurements were made on the stack emission levels for particulates, NO/sub x/, SO/sub x/, and chlorine. Noise and particulate levels in the working area were also determined. Also, estimates were made of ambient particulate concentrations. The data show that the coal-oil mixture can be used as a fuel in a slot forge furnace in many areas but some stack particulate collection will be required in some states. A 75% reduction in particulate emissions would allow the furnace to be located in all but one of the states. Routine use of the fuel will require some minor furnace modification to satisfy OSHA ambient work area regulations. (ERA citation 05:034123)
