CHAPTER ONE
INTRODUCTION
1.1 Background of the Study
Fuel
burning devices are devices that produce heat (thermal energy), derived
from burning fuel and required for technological processes especially in
the industry [Kittle, 2000]. There are so many types of burners with
different fuel types. Examples of such fuel are the biodiesel, ethanol,
vegetable oil etc. Burning devices that make use of this fuel are
classified as the oil burners, liquid fuel burners, and the combined gas
liquid fuel burners. Apart from its classification by the type of fuel
used, a burner can also be designed based on factors like the combustion
chamber geometry, type of oxidizer and also heat transfer requirements
which include flame temperature and heat distribution etc. Typical
examples of burners which are developed based on the type of oxidizer
are the oxy-fuel burner and air fuel burner [Baukal, 2014].
Various
works relating to the construction and testing of burners were studied,
they include: Development of a high velocity burner for furnace
operation. The main components of this burning device are the burner
nozzle, mixing tube, downstream section and a cross-connected regulator
for air fuel ratio control. It employs forced draft in mixing the fuel
and air [Ighodalo, 2010]. Design, Construction and Performance
Evaluation of a Biogas Burner, the work was geared towards modification
and improvement of the burner and its efficiency [Obada, 2018]. Porous
Radiant Burners which make use of liquid petroleum gas were also
developed and tested for cooking applications [Mishra et al., 2013].
Other authors studied the Design and Construction of Atmospheric Gas
Burners where they dwelt most on the theory of flow of gas through
different types of orifice [Walter, 2017].
In University of
Maiduguri’s Faculty of Arts, burners of different types have been
constructed for use in the kiln for firing or drying of things such as
the bricks. A typical example is a burner that uses kerosene only as its
fuel. The burner is made up of the nozzle, manual pump, hose and the
fuel tank. The pressure required for ignition is supplied by the manual
pump which is fixed at a small opening on the fuel tank. Kerosene then
passes through the nozzle as it comes in contact with heat supplied by
the rings in the kiln. This type of burner is classified as a liquid
fuel burner.
Similarly, a burner that uses only used or waste engine
oil has its fuel tank located at a certain height and uses electricity
which powers the electric motor and helps rotate the blower which
supplies the air required for combustion as the used engine oil flows
through the burner. Despite the presence of the few types of burner,
they are not constructed for carrying out foundry applications. Also,
considering the availability of used engine oil, there stems the need to
construct an admixture burner for the purpose of carrying out foundry
operations.
This paper therefore presents the result of the design,
construction and test of a two-faced gas burner for users as an
alternative to electric burners. The construction of a two-face gas
burner will go a long way in achieving portability of gas burners and
also enable asynchronous usage as two objects can be placed on the
burner at the same time. It is a starting point of actualizing a
functional technology in the country. Irrespective of the fact that
there are several breads of gas burners in the market, especially the
ones imported, we deemed it necessary to work further on it as a way of
modifying the brand with cast not left out in such modification.

ABSRACT - [ Total Page(s): 1 ]This project deals with the construction and fabrication of a two face gas burner. The gas components consists of the following major components; burner, injector opening, mixing tube, burner support, etc. The gas stove was constructed from medium carbon steel material. The choice of the selected material has to do with cost, and local availability. The distance between the cooking pot and the stove burner is 40mm, and the gap between each of the port is 5 mm. Mixing tube lengths of 80mm, tube i ... Continue reading---
