Numerical Investigation Effect of the addition of palm fronds on the burning of coal-fired boilers tangentially

Biomass co-firing is an appropriate and cheap solution for achieving renewable energy targets towards net zero emissions because it can reduce the potential environmental impacts associated with burning fossil fuels. CFD simulations were carried out by adding palm frond biomass with a ratio of 5% and 95% LRC coal, which was injected into the boiler combustion furnace. The boiler operational parameters used in this simulation are a coal flow rate of 151.75 tons/hour and an airflow rate of 1184.33 tons/hour on the research subject PLTU Pacitan with a capacity of 315 Mw. The results show that adding palm frond biomass to burning coal changes calorific value, affecting the combustion process's high temperature. However, it has a good impact from the operational side of burning coal particles.
