Product Development Using CFD Simulation of Energy Efficient Institutional Bio-char Rocket Stove



Globally, biomass accounts for ten percent of energy production, two-thirds of which is used for cooking and heating purposes in developing countries. Environmental degradation and natural resource depletion are also serious issues as a result of cutting trees to serve as fuel wood; biomass will govern household energy of the countries in the near future and increased afforestation, reforestation, and forest management to increase carbon sequestration in forests and woodlands. This study was product development using CFD simulation, of modified rocket stove that is energy efficient for institutional cooking. The stove design was selected for both the computational fluid dynamic (CFD) simulation and prototype production. ANSYS fluent work bench was used for CFD simulation the wood combustion and pyrolysis of woodchip to form multi-face exhaust holes syngas flow to stove combustion chamber. Gasses start to come out from the pyrolysis chamber through the exhaust outlet after 8 minutes of pyrolysis, and pressurized gasses come out at this time, and start burn in combustion chamber. At 60 minutes pressurized Syngas stops and gives low combustion.
