“…The experiments were carried out to measure the energy consumed for supplying suitable heat required to heat 5 kg of water to boiling point (100 o C), sensible heat to heat the vessel to 100 o C and, heat of vaporization of a known quantity of water at 100 o C at atmospheric pressure and the heat of combustion of the fuel consumed. Thermal efficiency is calculated using the formula given below [4], [18], [19]:…”

“…This value is close to the thermal efficiency with kerosene of about 30%. As a comparison, Makonese [19] observed that vegetable oil showed ±41% thermal efficiency compared to ±30% thermal efficiency with kerosene. From these studies, it is clear that VCO gives an average more efficiency than kerosene with the VOPS due to the higher calorific of VCOs and good atomization of VCOs produced to have better combustion.…”

Liquid petroleum gas (LPG) and kerosene can be substituted by vegetable cooking oils (VCOs) as fuel using the pressurized cooking stove. The higher of ignition values, density, and viscosity of VCOs compared to other oils, such as kerosene was a basic consideration to modify the vegetable oil pressure stove (VOPS). The VOPS design employed with spiral coil pipeline as oil preheater that was intended to reduce viscosity and ignition values of VCOs. The spiral coil pipeline in this VOPS will auto preheat the oil to decrease its viscosity and to produce smaller droplets before being combusted. The performance indicators fuel/stove/vessel combination were conducted by measurements, calculations, and experiments. The performance parameters were represented by fuel characteristic, oil droplet diameter, combustion flame and fuel consumption. The main purpose of this experiment was to study the use of VCOs as alternative fuels as well as combustion performance and economic evaluation. The experiment was conducted by using three kinds of VCOs as fuel; used vegetable oil (UCO), crude VCO and fresh UCO on VOPS. The VCOs could be burned in a red-bluish flame with a maximum flame temperature of flue gases of 1100 °C, 1042 °C, and 920 °C, respectively. Atomization of all VCOs could produce fuel droplets diameter of 155 µm-650 µm and lower viscosity and lower ignition values of the fuels. The efficiency of the VOPS was 20%-32% calculated by the fuel consumption rate (FCR) of ±1.50 L/h and gave the economic values were cheaper than using kerosene or LPG as fuel.

“…The emission factors are reported on a fuel mass basis, normalised to 0% excess oxygen, over a full 60 minute combustion cycle. Of the three devices/fuels tested, only the methanol stove reports a combustion efficiency below the SABS reference valuethe SABS 1906 [15](2009) code for liquid fuelled stoves specifies that the CO/C02 ratio should be below 2%. Despite the particular make and model of the kerosene stove being certified to comply with the SABS 1906, the combustion efficiency of the tested model was 2.3 times higher than the limit.…”

Research has shown that there is a clear link between emissions from inefficient domestic cooking appliances and the prevalence of respiratory infections and cardiovascular diseases. This has prompted the need for the development and dissemination of efficient clean cookstoves for cooking and heating purposes. Although liquid fuels are rated cleaner than traditional solid fuels, their combustion in basic and poorly designed stoves leads to problems of household air pollution and fire hazards. Information on the combustion, pollutant emissions and thermal performance of liquid fuel stoves is still scarce and there is a need to address this gap. This study characterises emissions and thermal performance of three liquid fuel stoves -kerosene stove, an ethanol gel stove and a prototype methanol stove. Kerosene/paraffin stoves are widely used in the low-income settlements in South Africa, while the ethanol gel and methanol stoves are new entrants in the market place. The 'hood' method was employed to collect the flue gases and particulate emissions, and to measure emission factors for the devices. The SeTAR Centre heterogeneous stove testing protocols (HTP) was employed to determine the average CO and PM25 emissions, as well as the CO/C02 ratio and thermal efficiency of each device. The methanol prototype stove reported better combustion efficiency compared to the ethanol gel and the kerosene stoves. Although the methanol stove has improved combustion efficiency compared to the other stoves, the fire-power is below the recommended standard and user expectations.

Abstract. Vegetable cooking oils (VCOs) and used vegetable cooking oils (UCOs) can be considered as alternative fuels which will provide the household with low price fuel and may solve the problem of getting rid of waste VCOs. Their utilization as cooking fuel can bring numerous benefits not only for urban but also for rural communities in Indonesia. The paper focuses on characterizing VCOs and UCOs as fuels for the household cooking application using a modified pressurized cooking stove. Physical properties such as auto-ignition point, auto-ignition time, flash point, density and viscosity of VCOs play the vital role in the combustion. Some properties of these oils were measured and characterized according to ASTM standards. The oil was used directly as a fuel using in a design modified pressurized cooking stove. Adjusting the temperature of vegetable cooking oils used as fuel, it is possible to improve their combustion performance, thus reducing ignition time and incomplete combustion. The main target of the research is to determine the quality and performances of these oils combustion. The auto-ignition point for the several oils was determined to be as follows: UCO: 460 o C, crude VCO: 406 o C, fresh VCO: 405 o C and the peanut cooking oil did not auto-ignite. Crude VCO gave the shorter auto-ignition time than other oils within 30 s. The efficiency of the pressurized stove using UCO, crude VCO and fresh VCO as fuel were observed 23.65%, 25.99%, and 31.57%, respectively. The highest flame temperature of 942ºC in these experiments was achieved by burning fresh VCO as fuel in this modified pressurized cooking stove. UCOs tended to produce luminous flames compared other oils.
