Atmospheric fluidized bed combustion gas erosion solution
The Westwood Generating Station is a 30 MW, anthracite culm-fired plant located near Joliet, Pennsylvania. The culm firing technology is based on the Combustion Engineering-Lurgi circulating fluidized bed combustion (CFBC) technology first introduced in this country in boiler applications in the mid-80`s. This unit went into commercial operation In July 1988 and is the second of its type in service in this country. It is located on the original site of the Westwood Colliery that was in operation from 1920 to 1950 preparing anthracite coal for the commercial market and leaving behind a 15 year fuel supply of anthracite culm, a coal screening waste, that is now the fuel for this station. This paper documents the investigations and corrective actions taken to stop severe tube erosion encountered in the combustor and heat recovery surfaces of the unit. This erosion is attributed to high gas velocities due to changing operation requirements and gas flow distribution.
