ABSTRACT
In order to solve energy crisis, the search
for alternative fuel is extensively important.
Alternative fuels selected should be renewable,sustainable and eco-friendly. In India, kerosene isalso used as a fuel in cooking stove. Kerosene
contains impurities like sulphur, aromatics andhydrocarbons, which causes environmental
degradation. In this experimental investigation,
blends of ethanol and kerosene were used asalternative fuel in kerosene wick stove without
any modification in stove design. The blends
tested were 5%, 10%, 15% and 20% ethanol inkerosene. The experimentations have been
carried out with an aim of obtaining comparative
measures of thermal efficiency and fuelconsumption rate. The values of thermal
efficiency and fuel consumption rate for blended
fuel were found to be comparable with kerosene.
The maximum value of thermal efficiency wasobtained with blend containing 5% ethanol while
the minimum value was obtained with reference
fuel. The fuel consumption rate for blend
containing 10% ethanol was found to bemaximum.

Keywords - Wick stove, Kerosene, Eco-friendly
fuel, Ethanol.

I. INTRODUCTION
Environmental pollution and fossil fueldepletion are matters of concern round the world. Inorder to solve tackle these problems, the search foralternative fuel has become significantly important.
Alternative fuels selected should renewable,sustainable and eco-friendly. In India, kerosene isalso used as a fuel in cooking stove. Kerosene stoves
have replaced the traditional wood-based appliancesthat are unhealthy and inefficient. However,kerosene itself also contains impurities like sulphur,aromatics and hydrocarbons which cause pollution.
On burning, it also produces very unpleasant smell.
Its smoke emissions create various respiratory
problems.
Kerosene is a thin, clear liquid formed fromhydrocarbons. It is obtained from the fractional
distillation of petroleum between 180°C and 250°C,
resulting in a mixture of carbon chains containing 10

to 16 carbon atoms [1]. It is widely used to power jet
engine, for heating and lighting.
In India, it is also used as a fuel in wickstove or pressure to cook food. Some of the fuelsthat can be used in cooking stoves are gaseous fuels
like biogas, solid fuels like wood, charcoal andliquid fuels like vegetable oils and ethanol. Use ofliquid fuels is preferable over solid and gaseous fuels
due to their high energy content, transportability,
storability and availability [2]. However, due to highviscosity and gumming tendency, vegetable oils are
not extensively used in cooking stove. These
disadvantages are not found in ethanol and thus
make it attractive alternative fuel.
Ethanol can be produced from renewable energy
sources such as sugarcane, corn, barley and manyother types of waste materials. Also, it has clean
combustion. Ethanol has lower calorific value anddensity as compared to kerosene.

The aim of this experimental investigation
is to study the effect of using various blends ofethanol and kerosene on performance of kerosene
wick stove. Pure kerosene was used as a reference
fuel. These blends were prepared on volume basis.
The blends tested were 5%, 10%, 15% and 20%
ethanol in kerosene.
The following nomenclature is used in thiswork: K: Kerosene; E05: 5% volume of ethanol and95% volume of kerosene; E10: 10% volume ofethanol and 90% volume of kerosene; E15: 15%
volume of ethanol and 85% volume of kerosene andE20: 20% volume of ethanol and 80% volume ofkerosene. The fuels used for entire testing belonged
to the same supply, to avoid the unnecessary
introduction
ofany
variation
duringexperimentation.

The experimentations have been carried out with anaim of obtaining comparative measures of thermal
efficiency and fuel consumption rate. All
experiments were carried out on unmodified stove.

II. EXPERIMENTAL METHODOLOGY
The experimental setup is shown in the Fig.
1. It consists of weighing balance, kerosene wickstove, a standard aluminium vessel, a stirrer and analcoholic thermometer. The experimental setup
consists of capillary fed wick stove. Test stove has 8
wicks of woven cotton placed in a holder such thatthey can be moved up and down by a control leveror knob. Wicks emerge into an annular spacesurrounded by two concentric perforated steel walls(the flame holder), which are spaced slightly wider
than the wick thickness. The lower ends of the wicks
are dipped into kerosene. The stove is lit byremoving the perforated steel flame holder raising
the wicks and lighting them. The holder is thenplaced again. The flame fills the gap between thetwo walls of the holder and emerges at the top of thestove. The flame can be raised or lowered byoperating the knob, when raised the flame burns
more intensely and the vice versa.

KeroseneIn India, the Bureau of Indian Standards(BIS) has set guidelines for testing the thermal
efficiencies of all types of cooking stove. Forkerosene cooking stove, the thermal efficiencies are

determined according to the specifications provided
by Indian Standards [3]. Following the guidelines,
thermal efficiency of wick stove in the present work
is estimated by conducting the water-boiling test andthe procedure followed is briefly described below[2-5].
The fuel to be tested is to be filled nearly ¾
of the capacity of the fuel tank. The aluminum vessel
was selected as the fuel consumption test. A
thermometer (0-150) was used to evaluate the watertemperature during experimentation. A stirrer madeof aluminum has been made for stirring the water for
uniform distribution of heat. An electronic balance(of least count 1 g) has been used for weightmeasurement of water and stove. The technicalspecifications of electronic balance are shown inTABLE 3.
The weight of vessel with its lid and theweight of water used in the vessel were noted. Initial
temperature of water (T1) was also noted. The
weight of stove along with fuel (W1) was noted. The
stove was lighted and water was warmed up to 800C
and stirred continuously for uniformity oftemperature. When final temperature of water (T 2)
has reached 800C, the stove was put off. Again, theweight of stove (W2) was recorded. The differencein the weight of stove (W2-W1) gives the mass offuel consumed for heating water by temperature (T 2T1). The thermal efficiency of the stove is expressed
as follows:

Where,
Ww = quantity of water in the vessel (kg),WAl= weight of the aluminium vessel (kg),Cw= specific heat of water (kJ/kg-K),
CAl= specific heat of aluminium vessel (kJ/kg-K),
T1= initial temperature of water (K),T2= final temperature of water (K),W1= weight of test stove before warming water (kg),W2= weight of water after warming water to 80 0C(kg).
The experiment was repeated three times
and average of the three values was taken as finalreading. The same procedure was followed for all
fuel blends.

III. RESULTS AND DISCUSSIONS
IV. CONCLUSIONS
Performance of the wick stove has been
evaluated in terms of thermal efficiency and fuelconsumption rate. Subsequent results as shown inbar graphs.
Fig. 2 shows the effect of blending on thethermal efficiency of the wick stove. It is clear fromthe figure that the can be seen that maximum valueof thermal efficiency was obtained with E05 i.e.
blend containing 5% ethanol. The minimum value ofthermal efficiency was 42.1% which was obtainedwith reference fuel operation.
The effect of blending on the fuelconsumption rate of the wick stove is shown in Fig.
3. It can be seen that the fuel consumption rate forE10 i.e. for the blend containing 10% ethanol while
for reference fuel its value was 4.01 x 10-5 kg/s.

The objective of work was to study theeffect of using various blends of ethanol andkerosene on performance of kerosene wick stove.
The blends tested were 5%, 10%, 15% and 20%
ethanol in kerosene. The results show that blends ofethanol and kerosene can be successfully employed
as used as alternative fuel in wick-stove.
Performance of the wick-stove operating on ethanolkerosene blends was evaluated in terms of thermal
efficiency and fuel consumption rate. The values ofthermal efficiency and fuel consumption rate forethanol blended fuel were found to be comparablewith reference fuel. The maximum value of thermal
efficiency was obtained with blend containing 5%ethanol while the minimum value was obtained withreference fuel. The fuel consumption rate for blend
containing 10% ethanol was found to be maximum.
It can be concluded that capillary fed multi
wick stove can be successfully operated withkerosene- ethanol blend up to 20% kerosene without
any design modification and operational difficulty.
