| Popis: | Design defects in a reactor often results in poor reactor performance. This study examined the effects of variations in burner holes and air to fuel ratio on thermal efficiency and emission characteristics of three locally fabricated gas cooking stoves with 48, 96 and 144 burner holes. The purpose of the study was to use the stove design with optimal efficiency and lowest emissions, as a model for improving the design of a gas-fired pyrolysis reactor that had air-fuel intake port defect with consequent incomplete combustion. The results of the study showed that stove with 96 burner holes produced the lowest emissions of 89.672 mg/m3 while stove with 144 burner holes was found to be the most fuel efficient with efficiency of 69.0. The results imply that a trade-off exists in the design of the burners to achieve either the most environmentally-friendly or most fuel-efficient burner. However, a compromise of the two objectives of maximizing fuel efficiency and minimizing emissions was reached by choosing as a model, the burner having 96 holes with thermal efficiency of 64.3% and emissions of 89.672 mg/m3 over burner having 144 holes with thermal efficiency of 69.0% and emissions of 258.974 mg/m3 .
