Emission and Energy Characteristics of the Combination Use of Coal and Biomass in Circulating Fluidized Bed Boilers (CFBB) in Steam Power Plant

Currently there are still many power plants using fossil fuels, including oil, gas and coal to produce electricity. The problem recently received by developing countries, Indonesia, is environmental degradation due CO, SO2 NOx emissions. Co-burning of biomass with in most countries one the economical technologies available today for significant pollutant reduction. This study tested combined combustion a direct co-firing Circulating Fluidized Bed Boiler (CFBB) two treatments, namely 5 wt% sawdust 95 coal, woodchip coal. results tests were compared parameters when 100 aims (1) analyze energy produced from burning combination biomass, (2) emission content, SO2, NOx. mixture produces 82 MWh gross electricity, higher than woodchips requires smallest amount fuel, 18.7 tons per hour. emitted lowest emissions other 2 cases, 71.5 mg/Nm3 222.4 CO was issued mixture, 4.0 ppm.
