Combustion Characteristics Modeling of Rice Husk as Fuel for Power Plant in Indonesia

Abstract:

This study was conducted to obtain a model combustion characteristic of rice husk as fuel at power plants in Indonesia. It is expected to be one of the solutions to meet the needs of electrical energy in Indonesia. Modeling characteristics performed using Ansys Fluent software. Modeling results obtained maximum gas temperature at bed about 1600 K. Temperature and CO₂, CO, H₂O occurs fluctuation in the combustion zone to at distance of 4.66 m from the fuel inlet. Maximum combustion temperature at the base of the furnace about 1600 K and the furnace exit around 967 K. Temperature distributions in the bed and the furnace is uneven due to incomplete combustion of gas in the bed and the fuel air mixture ratio is not appropriate (stoicheometric). Combustion gases in the furnace, ie CO₂, CO, H₂O fluctuations at the basic furnace, the furnace chamber, and the furnace exit. It was concluded that the model of combustion characteristics of rice husk can be used as a basis for assessing the feasibility of utilization as fuel for power plants.
