The Performances of Okpara Coal, Enugu State, Nigeria, in Fluidized Bed Combustion

摘要

A fluidized bed, using locally available material for the combustion of Okpara coal for generating steam to drive turbine for electricity generation, has been designed, constructed and commissioned. Two areas of investigation were looked into in this research. These were combustion at different coal particle sizes from 4.5-50.0 mm and steam generation at constant coal particle size with bed temperature ranging between 700 and 900°C. Results shows that a temperature of 153°C maximum was obtained at atmospheric combustion and much higher temperature could be anticipated at higher pressure with this type of bituminous coal and combustor.
