Energy Reduction from Coal Handling in Indonesia
Energy

In accommodating customer demand and blending various coal types, the utilization of Low CV coal sourced from third parties has been favored. However, this type of coal tends to cause blockages within chutes during the rainy season, disrupting the seamless transfer of coal between conveyors. Such blockages not only prolong cleanup efforts but also interrupt loading processes. Traditionally, chute blockages were managed using labor-intensive techniques like high-pressure water spraying or manual removal, which were constrained by limited staff availability.
In response to the operational inefficiencies and environmental concerns linked to excessive water usage, Bontang Coal Terminal (BoCT) in Indonesia introduced an innovative solution in March 2022: “the installation of air cannons in transfer chutes”. These cannons autonomously release periodic air blasts to clear material buildup. Since implementing this system, remarkable improvements have been observed:
80% reduction in delays and cleanup times due to chute blockages
5% increase in gross loading rate
Annual reduction in energy consumption by approximately 538 MWh, leading to a decrease in GHG emissions of around 125 tCO2e per year.
These outcomes underscore the effectiveness of the air cannon system in enhancing operational efficiency while mitigating environmental impacts.
