Evaluation of cofiring application in power plant's coal combustion

Abstract

Steam Power Plant (PLTU) is a power plant that uses coal as an energy source to generate electricity. Burning coal to produce energy will produce residues in the form of carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), as well as bottom ash and fly ash which is harmful to health and the environment. To reduce pollutant emissions, RS-PLTU has implemented a co-firing system using sawdust. After 8 months of testing, it was seen that there was a decrease in exhaust emissions which could be monitored from CEMS. The total use of sawdust was 10,313.9 tons, which was only 0.54% of the initial consumption target. While the total KWh green produced is 11,108 MWh. The sawdust used comes from the waste from the local wood industry to build the local people's economy.
