ABSTRACT

This project is an equipment which been fabricated for the principle purpose of producing heat energy for commercial use by burning solid fuel like briquette. The project which is the fabrication of briquette stove was made from preferentially selected engineering materials like mild steels of different gauge member and metallic rod.

These metallic materials posses some mechanical properties like malleability, ductility, static strength and have the capability of with standing high tensile stress which can be noted in the area of filming of the materials used in the fabrication.

During fabrication, the follow sequence of operation was undergone. This includes design-material selection-fabrication evolution-and possible redesign and or modification. Screw design was found to be an area requiring major design improvement. Several experiments were conducted with different screw design, and an optimum design was arrived at. Problems concerning screw life was studied to enhance operating life of screws. Prototype briquetting machines were also fabricated after adaptive research in early day when briquette stove fabrication and construction.
The fabrication process of the metallic materials (briquette stove) include measuring out, marking out, cutting, filing, welding and painting as finishing touches. The materials used in the fabrication of this equipment are selected in order to withstanding the service environment like corrosion due to external agent; air, moisture and also due to continuous production of flame and heat especially on the reflector, gauze and top plate of the equipment stove.

The technology did not attract enough attention until recent time when the consumption of energy escalated to a greater height; an attempt was made to introduce this technology to Nigeria to alleviate the problem of energy and cooking equipment.
After the fabrication of the project, the efficiency of the briquette stove fabricated was tested and raised to be 89% effective, which shows and vindicates that the aim of the fabrication was achieved.

At the end of the fabrication, the cost of materials, labour and overhead costs were calculated on analytical bases, to ensure accuracy of the fabrication and its general usage.

CHAPTER ONE

INTRODUCTION
About fifty percent of the ten million rural household lack access to electricity. To improve this situation, the government approved in 1996 a plan to electrify sixty percent of the households by 2000 and seventy percent by 2010. Despite an aggressive grid bases rural electrification program, there will remain over 3million rural household having no access to electricity in 2010.

Nigeria is well endowed with renewable energy resources. Which could be used to generate electricity to serve rural communities and the national grid in an effective, economic and environmentally way. Hydropower potential for small-scale generation (under 10 mw/site) is estimated at about 2,000 mw. With sugar and rice production expanding rapidly, opportunities exist for economic power generation using bagasse and rice husk. Solar radiation levels are good in the southern and central regions (with an average sunshine duration of 2,750 hours/year). Wind speeds are adequate to good in the coastal arrears and offshore islands. Over the past two decades many pilot projects have been undertaken in Vietnam to demonstrate the technical feasibility of renewable energy technologies for remote power supply. These demonstration projects have built indigenous technical capacity in small hydro, solar PV and small wind turbine.

The infrastructure facilities in Vietnam are adequate to manufacture heated-die screw-press briquetting machines based on adaptation and modification of foreign briquetting technologies. With this background, the sida-funded project attempted to develop a market for briquette and briquetting machines in the country.

To gather expertise in the technology, institute of energy of Vietnam sent researchers to AIT as well as to Bangladesh institute of technology (BIT) Khulna. The researchers gained hand-on exercise in the operation and maintenance of briquetting machines.

Sequel to that, the document is the result of a mission to Lukla/mosi (8,000ft./2634m) and Khumjing (11,8000ft,3882m) in the klaumbu region and contains observations about the use of the beehive charcoal briquette stove for cooking and space heating. The beehive charcoal briquette stove has the potential to become a practical source of renewable energy (RE) for domestic use, hotel owners and trekkers in high altitude camping grounds. A currently large amount of kerosene is being brought into the region to satisfy the need for cooking energy and for use in Everest base camp. The observations in this report are related to the potential use of biomass charcoal briquettes and improved briquette stoves at high altitude in Nepal. With proper application of the available technology, biomass briquettes can be a means of providing a convenient source of energy for cooking and space heating, substituting the need for kerosene which is a no-renewable energy source for busijised by the Nepalese government. The need to improve the locally manufactured biomass charcoal briquettes has been also identified by WWF Nepal programme. The same problems in the supply of energy exist in similar high mountain regions; such as the conservation areas managed by the WWF-Nepal programme and the king mahendra trust for nature conservation. The charcoal briquettes are manufactured from agricultural residue and forest waste products. High firewood consumption for domestic cooking and heating purposes is depleting forest reserves because at the high altitudes, where tree growth is considerably slower than at the lower altitudes such as in the terai, regeneration of firewood cannot meet the demand.

Energy availability and efficient supply make up the engine of economic development. Fortunately, Nigeria is blessed with abundant energy resources; oil, gas, coal wood, biomass geothermal, solar, wind nuclear (radio-active) and hydropower. Unfortunately, only the gas and oil resources have been developed to the stage of over dependence for the country’s industrialization process at the negligence of the other abundant energy resources such as coal, in spite of this, the country has continued to suffer from indeciduate and irregular supply of us able energy for industrial, agricultural and domestic applications. Moreover commercial energy in Nigeria is produced and delivered at a cost most Nigerians can ill afford. As a result, a greater percentage of the growing population have resorted to dependence on the country’s forest resources as a source of fuel for agricultural, domestic and small scale industrial activities in semi-urban and rural areas. This in turn has given rise to deforestation with its attendant environmental degradation of desertification in the Northern parts of the country and soil erosion and loss of topsoil fertility in the south.

Of all the available energy resources in the country, coal and coal derivatives such as smokeless coal Briquettes have been shown to have the highest potential for use as suitable alternative to fuel wood (firewood) and there fore will serve as the most direct and effective method of combating deforestation in the country.

Fabrication Of Briquette Stove:

Creating a briquette stove involves a relatively simple process using readily available materials. A briquette stove is designed to burn briquettes, which are compressed blocks of biomass or other combustible materials, efficiently for cooking or heating. Here’s a step-by-step guide on how to fabricate a basic briquette stove:

Materials and Tools:

Metal sheet or drum (for the stove body)
Grate or wire mesh (for the combustion chamber)
Metal rods or bars (for support and legs)
Insulating material (e.g., clay, sand, or vermiculite)
Briquettes or biomass fuel
Metal cutting tools (angle grinder, hacksaw, or tin snips)
Welding equipment (optional, for more complex designs)
Heat-resistant paint (optional)

Steps:

Design the Stove:
Decide on the size and shape of your briquette stove. A basic design typically includes a combustion chamber, a fuel chamber, and a grate to hold the briquettes. You can create a simple cylindrical or rectangular shape.

Cut the Metal:
Using your chosen metal cutting tools, cut the metal sheet or drum into the desired shape for the stove body. Make sure to create an opening for the fuel chamber and a lid for access.

Construct the Combustion Chamber:
Inside the stove body, place a metal grate or wire mesh about 2-4 inches above the bottom. This will serve as the combustion chamber. It allows air to flow beneath the briquettes and supports the burning process.

Create the Fuel Chamber:
Adjacent to the combustion chamber, create a cavity or chamber where you’ll place the briquettes. This should be designed to hold enough briquettes for your cooking or heating needs.

Add Support and Legs:
Weld or attach metal rods or bars to the bottom of the stove body to serve as support and legs. This will elevate the stove, allowing airflow beneath it and preventing the surface it sits on from overheating.

Insulate the Stove:
To improve efficiency and reduce heat loss, insulate the stove. You can use materials like clay, sand, or vermiculite to fill the space between the inner and outer walls of the stove body. Make sure to leave openings for airflow.

Test and Paint (Optional):
Before using the stove, do a test burn to ensure it functions properly. If desired, you can apply heat-resistant paint to the exterior of the stove for a more finished look and added durability.

Use and Maintain:
Load the fuel chamber with briquettes and light them. The stove should provide a controlled and efficient heat source for cooking or heating. Make sure to clean the grate and empty ash regularly for optimal performance.

Remember to take safety precautions when working with metal and heat. It’s also essential to consider the proper ventilation of indoor spaces when using any type of stove indoors to prevent carbon monoxide buildup. Additionally, always follow any local regulations or guidelines related to stove construction and use.
