ABSTRACT

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 inner diameter of 15mm, and gap diameter of 2.5mm between each ports were adopted in this design. The results obtained show that an average efficiency, minimal efficiency, optimal efficiency of 56.894 %, 46.02 %, and 63.87 % respectively were obtained. Also, an average mass of water of 3.5 kg, an average evaporated mass of water of 0.0208 kg, and an average mass of fuel of 0.0551 kg were obtained. With this designed and adoption of two face biogas fuel stove as means of cooking, the usage of wood and fossil fuel will be reduce, thus preventing the liberation of hazardous gases to our eco-system and increases cooking speed.

CHAPTER ONE

INTRODUCTION

  • 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.

 

 

  • Statement of the Problem

In an effort to develop an economical means of cooking, different people and institutions have come up with different designs and innovations of cooking gadgets. Nevertheless, each design comes up with its peculiar limitation especially with reference to the environment in which it is being used. A look at the different types of burners available helped us to understand the importance of this particular work. Many burners currently in the market are single faced. With this, cooking slows down since one thing must be cooked before the other is started. This causes wastage of time and resources

Although there are already developed two face burners in the market, most of them do not utilize the principle of minimal gas combustion. Since they are two faced, they waste more fuel than required. This study tends to curb the current problem by designing a two face gas burner capable of asynchronous usage, generate minimal heat and minimize fuel usage.

  • Aim and Objectives of the Study

The main aim of this study is to construct a two face gas burner. To achieve the stated aim, the following specific objectives were laid out:

  1. Construct a burner that does not pose health risk to the user and is environment friendly, i.e. applies complete combustion of gas.
  2. The burner should be safe, simple and easy to operate and maintain
  • The burner should be able to produce enough useful heat with minimum energy loss.
