A Review of Biomass Cofiring As An Effort for Maintaining Steam Power Plant Performance In Indonesia
Keywords:
Biomass, Cofiring, Power Plant, BoilerAbstract
Nowadays, fossil fuel like coal, oil, and natural gas represents primary energy resources in the world. However, the depletion of fossil fuel reserves and human population growth contrast with human energy needs. It also created more environmental problems such as global warming and high carbon emissions. Biomass is one of the earliest sources of energy with specific properties. It can be converted into any other form of fuel but needs special treatment. Co-firing biomass with coal can provide a range of opportunities, such as reducing fuel costs for some companies and minimizing greenhouse gas emissions to protect the environment. In this review, several aspects which are associated with cofiring biomass in boilers have been investigated such as the effect after using biomass to equipment performance, exhaust gas emissions, and any other problem like slagging or fouling in boiler caused by biomass, what we can do to improve biomass quality in the future to implemented high percentage cofiring. From this review, we want to show what the best way Biomass cofiring for maintaining Steam Power Plant performance in biomass cofiring in Indonesia such as Pellet Biomass. There are more than 85 million ton / year pellet potential in Indonesia with some power plant already using biomass to cofired with coal more than 29 thousand ton per year in East Indonesia Region power plant. The future of biomass in Indonesia depends upon the development of the markets for fossil fuels and on policy decisions regarding the biomass including the premium price of biomass, the ability to establish stable feedstock supply chains, and a range of technical challenges.
