The properties of vegetable cooking oil as a fuel and its utilization in a modified pressurized cooking stove

Abstract

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.

Characteristics Study of Liquid Fuel From Pyrolysis of Polyethylene Plastic Waste

“…These physical properties were measured using volumetric glassware and hydrometer, respectively according to appropriate procedures. The obtained value of PLF density and viscosity was used to determine the oil energy content (heating value) of the oil according to a widely used and high accuracy correlation equation [13,14]. ASTM D92-2005 of Cleveland open cup standard test method was adopted to evaluate the combustion properties of smoke point, flash point, auto-ignition point [15].…”

Fuel Oil from Municipal Plastic Waste through Pyrolysis with and without Natural Zeolite as Catalysts

“…The viscosity of the fuel oil was measured by utilizing the Cannon-Fenske type 200 viscometer as suggested by ASTM D445. The fuel oil viscosity is calculated by the following equation [13]:…”
