Abstract
The use of renewable energy resources is broadly increasing for power generation, so the engine quality producer gas which comes from gasifier must be evaluated for engine applications. The Internal Combustion Engine (ICE) generates electricity for lighting & other end uses. The system consists of a gasifier coupled with ventury scrubber, coarse filter filled with wood chips; two fine filters filled with saw dust and one security fabric filter. The gases produced are cooled in water scrubber and then tar is removed in subsequent filters and gases are supplied to Spark Ignition Engine for operating AC Generator set. The unit is tested with resistive loading, which increases gradually from 20 %, 40 %, 60 %, 80 % & 100%. The cold and hot gasification efficiencies are 75.41% & 80.85 % respectively. The biomass consumption rate is 27kg/h. The air and gas flow rate are measured 20.79 m3/h and 79m3/h respectively.The temperature above the grate is 603℃. The tar level after gas cooling and cleaning unit is counted 9 mg/Nm3.
Highlights
Though producer gas as a fuel has been known since 1785, gasifier use with engines for power generation came into existence only around 1920
The possibilities of using this gas for heating and power generation was first realized by Europe, this gas emerged in Europe producer gas system which used charcoal and peat as feed material
Mukunda [5] suggested the use of dry sand filters after a wet scrubber to be an effective way of removing particulates and tar from producer gas
Summary
Though producer gas as a fuel has been known since 1785, gasifier use with engines for power generation came into existence only around 1920. The possibilities of using this gas for heating and power generation was first realized by Europe, this gas emerged in Europe producer gas system which used charcoal and peat as feed material. Sims [1] suggested the wood biomass as a greatest potential fuel for electricity generation in New Zealand. Narvaez [2] reported biomass gasification with air and effect of several variables on performance of gasifier. The dry sand bed was used to remove additional tar and dust from gas. Mukunda [5] suggested the use of dry sand filters after a wet scrubber to be an effective way of removing particulates and tar from producer gas.
