1. INTRODUCTION
It is know that gasoline, diesel, and turbine engines
could soon burn cleaner or be more fuel efficient through
the application of Plasma Assisted Combustion. The
technology consists of an electronic device that can be
attached to an existing fuel injector that applies electrical
voltage to the atomized fuel stream prior to combustion -
generating a plasma in the fuel. This effect essentially
breaks down the long chains of hydrocarbons in the fuel
into smaller parts - allowing the fuel to be burned more
completely, resulting in more miles per gallon, or
reducing harmful emissions. The using of plasma for
rocket engineering can to help resolve a series of
additional problems. It is the fuel regression rate [1] or
steerability of rocket engine wholly. The general
advantages of paraffin as a green fuel are high caloricity,
ecological compatibility, safety of keeping and high
chemical inertness to external factors, etc. [2]. The results
of assembly investigations of plasma assisted stearin
combustion and paraffin fusion kinetics are represented in
this work.
2. EXPERIMENTAL SET-UP
104 PROBLEMS OF ATOMIC SCIENCE AND TECHNOLOGY. 2011. № 1.
Series: Plasma Physics (17), p. 104-106.
The commercial stearin was used as a investigated
paraffin. Scheme of plasma dynamic system (PDS) for
plasma assisted stearin combustion (PASC) are shown in
Fig. 1. It consists of main stainless steel chamber (1), in
which through a dielectrics (3) two copper electrodes by
diameter of 4 mm are entered. Transversal blowing arc
(TB-Arc) was used as plasma source. The gas was
injected into the main chamber tangentially to the copper
electrodes and flowed out through the gas gape between
copper electrodes in the form of plasma torch (4) into the
cylindrical stainless steel chamber (6). Plasma torch (4)
was enclosed by cylindrical steel net (5). Steel net (4) by
diameter 1 cm and length of 4 cm was attached to the
cylindrical chamber (6). Space between net (5) and
chamber (6) was filled by the stearin (7). The voltage was
supplied between the water-cooled copper electrodes (2)
with the help of the DC power source (PS) powered up to
10 kV. Air flow was created by compressor and
controlled by rotameter in range from 0 to 500 cm3/s.
Static pressure outside the chamber was ~1 atm.
The flame (8) was formed during the discharge burning in
the stainless steel chamber. The voltage between copper
electrodes was registered by voltmeter (V) with the step
of 200 V. Discharge current was registered by ammeter
(A) with the step of 20 mA.
Fig. 1. Scheme of PDS PASC
Diagnostics of the TB-Arc plasma and PASC was
conducted by means of optical emission spectroscopy.
Optical system consists of optical head (9), which focused
parallel beams on optical fibre input, spectrometer Solar
TII (11), computer (12). Fig. 1 shows scheme of
experimental set-up for diagnostic of the PASC flame (8).
Cylindrical chamber (6), cylindrical net and stearin for
diagnostic of the TB-Arc plasma torch (4) were detached
from the main chamber.
3. RESULTS AND DISCUSSIONS
The typical current-voltage characteristics of the TB-
Arc working with stearin at different airflow rates are
shown in Fig. 2. The voltage was decreased with
increasing of discharge current. Trend lines have
approximately slopes at minimum (grey) and maximum
(black) air flows.
The current-voltage characteristics of the TB-Arc
working with stearin and without stearin at airflow rate
G=55 cm3/s are shown in Fig. 3. Trend line for regime
with stearin have steeper slope than for regime without
stearin. Stearin vapour hindered discharge burning.

and without stearin at airflow rate G=55 cm3/s
Fig. 4. Emission spectra of plasma torch (without stearin) and flame (with stearin)
Emission spectra of plasma torch (without stearin) and
flame (with stearin) at discharge current 300 mA, voltage
0,6 kV, air flow 55 cm3/s are shown in Fig. 4. Emission
spectra were normalized on their maximum of intensity
(with stearin λ=588,99 nm and without stearin
λ=324,75 nm). Bands of hydroxyl OH, monoxide NO and
lines of copper Cu (324,75 nm; 327,39 nm), sodium Na
(588,99 nm; 589,59 nm), potassium K (766,49 nm;
769,89 nm) are in Fig. 4. Emission spectra of flame at
plasma assisted stearin combustion are close to blackbody
spectra.
To determine rotational temperature Tr
* SPECAIR [3]
was used. Rotational temperatures measured by hydroxyl
bands OH were Tr
* = 2700±500 K for regime without
stearin and Tr
* = 2300±500 K for regime with stearin.
Flame temperature was obtained (T= 2500±100K) by
original technique. Emission spectra of blackbody at
different temperatures in range from 1200 K to 3000 K,
with step by 100 K, were calculated and normalized
(λ=900 nm). Equation 1 for spectra calculating was used:

The kinetics of n- paraffin melting (С18Н38 and
С22Н46) was investigated for paraffin temperature above
melting temperature with using of author’s patented
method [4]. The melting was supervised simultaneously
during measurements of shear modulus. The typical time
profiles of shear modulus represented in Fig. 5, 6.
Fig. 5. Time profile rigidity modulus: С22Н46

Fig. 6. Time profile rigidity modulus: С18Н38
It was determined that the time of full melting for
С18Н38 – sample was 14 for fused С18Н38 is null and for
С22Н48 isn’t null. It specifies on that the structure of first
substance melt is the liquid and structure of second is the
elastically - viscosity object.
The time profile of squared diameter changing for
paraffin particles was measured during burning process at
burning kinetics investigation. The combustion of paraffin
particles was made with using stationary torch. The
obtaining experimental results were enabled to define
burning constant rate. It was 0,402 mm2/s.
The paraffin weight in reactor to combustion was 3 g.
The time of full fuel combustion was ~ 20 s for value of
air flow into reactor 150 cm3/s. The steady torch was
existed for ratio of fuel energy to energy that was inputted
to electrical discharge ~ 100 (= 136,8 / 1,2).
4. CONCLUSIONS
The basic components on emission spectra of TB-Arc
plasma are the bands OH, NO and lines of electrodes
material (Cu).
Emission spectra of flame at plasma assisted stearin
combustion were close to blackbody spectra.
Temperature of flame at plasma assisted stearin
combustion was ~ TPASC = 2500±100 K.
Ratio of fuel energy to inputted energy into electrical
discharge was ~ 100.
