CWF firing experience in the Sundbyberg Heating unit
This paper describes Combustion Engineering's participation in a Swedish research program designed to demonstrate the use of coal-water slurry fuel (CWF) in a previously oil-fired, 18 MWt district heating plant boiler. Program emphasis was placed first on defining the technical specifications for the conversion of the boiler to CWF firing, and second on the demonstration of boiler operation with CWF for several heating seasons. Long term boiler operation on CWF has been an integral part of the program in order to make a valid technical and economic evaluation of the fuel as a substitute for conventional fuel oil. This paper highlights activities surrounding the supply, initial trials and long term testing of these burners. Approximately 2000 hours of boiler operation during the 83, 84 and 85 heating seasons has confirmed the suitability of CWF as an alternative boiler fuel. The long term testing identified the need for further equipment upgrades predominantly in the flue gas and ash handling systems. These equipment modifications have been completed, with additional boiler operation on CWF to follow.
