Wais (Waste automotive ignition stove): an eco- efficient stove with automated oil control mechanism
Keywords:
Waste Automotive Ignition, Stove, Fuel Efficiency, Environmental Impact, Emissions, DurabilityAbstract
This study investigates the development and performance of the Waste Automotive Ignition Stove (WAIS) prototype, designed to use waste engine oil as a cooking fuel. The primary objective was to assess its efficiency, environmental impact, durability, and economic feasibility as an alternative cooking solution. The WAIS prototype demonstrated a heat output of 4.5 kW, which was superior to charcoal stoves (3.2 kW) and comparable to butane stoves (4.0 kW), while maintaining a fuel consumption of 0.35 liters per session, highlighting its fuel efficiency. In terms of environmental impact, WAIS reduced waste oil disposal by 85% and emitted 50 ppm CO and 35 ppm NOx, which was lower than charcoal stoves but higher than butane. The stove's automated oil control system reduced fuel wastage by 30% and mitigated fire risks. Durability tests revealed that the prototype required minimal maintenance, with only one check-up in six months.
Based on the findings, it is recommended to enhance emission control through filtration technology and further improve the stove’s combustion efficiency. Additionally, long-term studies should be conducted to assess the stove’s durability and real-world performance, while efforts to promote waste oil recycling and user safety should be prioritized for broader adoption.
