| Summary: | Coal is a fossil fuel commonly used as a source of energy in various sectors. Coal
consumption needs to be reduced because it emits large amounts of greenhouse
gasses (GHG). Co-firing coal with alternative fuels such as refuse-derived fuel
(RDF) and rice husks is expected to reduce coal consumption. Emissions from cofiring coal with alternative fuels need to be studied to evaluate and control
environmental impacts. This research objective is to determine the effect of cofiring on its emission characteristics. The fuel samples used consisted of coal,
mixtures of coal and RDF, and mixtures of coal and rice husk with alternative fuel
compositions of 0%, 5%, 10%, and 15% by mass. The parameters measured consist
of the composition of black carbon in fine particulate matter (PM2.5) and the
concentration of CO2, CO, NOx, and SO2 gasses. Based on the result of the study,
the measurement of black carbon by optical methods is not accurate in emissions
with high concentration of particulates. Co-firing with RDF reduces NOx and SO2
emissions. Co-firing with rice husk reduces SO2 emissions. Implementation of cofiring of coal with 10%-heat of rice husk at PLTU Suralaya Units 1-4 reduces GHG
emissions by 10.60%. |
