| Bark has been widely used as the primary fuel of bubbling fluidized bed (BFB) boiler plant in pulp industry, but due to current technology, bark has become more valuable in many other sectors such as medicine, etc. Therefore, primary fuel transition from bark to palm wastes will be one of the solutions. This research brings up the feasibility study on burning palm wastes as primary fuel transition from bark into the existing BFB boiler in order to have further understanding on direct impact to boiler steam capacity, temperature and pressure. This research analysis will be based on assumption experience synthetic methods. The operational and performance test was carried out by analyzing the fuel (palm wastes as primary fuel), ash and sand sample, to evaluate its chemical composition and physical properties for better understanding on combustion process, where boiler process parameters from installed sensors/transmitter were monitored directly through display control system (DCS). At the end of test, boiler burning palm wastes were only able to generate 129 ton/hr - 482°C – 62 kg/cm2 which corresponded with 65% maximum continuous steam rate (MCR) compare to original design using bark as primary fuel – 200 ton/hr – 490 °C – 84 kg/cm2. |
