Abstract

In 2021, Indonesia’s renewable energy usage reached 15%, short of the 23% target set for 2025. To increase the renewable energy mix, PLN implemented biomass co-firing in existing coal-fired power plants. Indonesia’s industrial waste has a biomass potential of 15,635.7 MWe, which still needs processing and adaptation to the current boiler specifications to keep investment costs low. Tests were conducted on a 300 MW pulverizer-type boiler power plant, designed for coal with a heating value of 4,200 kCal/kg, using 5% sawdust biomass. The purpose was to assess the impact of sawdust addition on plant equipment and emissions by comparing coal-biomass mixture combustion to 100% coal combustion. Sawdust, having lower sulfur content, lower heating value, and higher volatile matter than coal, led to the mill working harder, as shown by increased mill current and outlet temperature. However, the air heater’s performance and steam production remained unchanged. Specific Fuel Consumption decreased by 0.01 kg/kWh during co-firing. Environmental emissions also changed, with SO₂ emissions reducing by 14.54 mg/Nm³ and NOx emissions by 4.95 mg/Nm³ during co-firing compared to using coal alone.
