ABSTRACT
This
project is concern about the construction of an electrical stove with three
oven apartment is described in his project. It was carried out in order to
solve the problem often encounter in cooking and drying and at the same time
finding an alternat6ive means to replace the use of kerosine and gas for
cooking and drying which are often not available due to scarcity of these
products, however, the project students have employed the use of electricity
which is rending available.
The
analysis of each stage of development of this equipment is cleearly described.
Having compared the results of this construction with those exsisting or parallel
ones, it was found out that it stands the test of time.
However,
the operation of this electrical equipment in not without limitation. For
precisely nine years now Nigeria has been facing power instability, and a
seizure of electrical power does disrupt the operation of this equipment, for
without which no source of its energy.
The
cost analysis also prove to a large extent to be relatively cheaper than most
modern cookers and ovens for domestic application.

INTRODUCTION/LITERATURE REVIEW
1.1 INTRODUCTION
This project
is as a result of increasing interest.
Essentially,
the idea, as demonstrated in an existing design, arises in the project students
a feeling of motivation, and hence the search for a way to bring it to reality
in a simple, yet intelligent design, like this.
1.2
PROBLEM STATEMENT
Specifically,
this design seeks for a source of energy that is relatively cheap and
available, and therefore has an edge over other stoves and ovens using kerosine
and gas as sources of energy. It also aims at making domestic cookers and
ovens safe enough as against highly flammable liquid or gas fuel.
Many
Nigerians today are faced with the problem of petroleum fuel scarcity and as
per cooking and drying which is not often easy to get fire wood from forests
that are often far away especially from the big cities. Equally too, the few
available fuels are of substandard quality with the attendant danger of fire
outbreak.
In
addition above, fuel consuming cookers and ovens have two outstanding
deficiencies, namely; sooty pre-heating and problem of dogged nozzles which
lead to offensive discouraging and dirty burning.
Above
all, deforestation as a result of fire wood consumption is causing great deal
of environmental problems in most regions of Africa. In this modern world and
its various invented means of cooking, it largely seems as if non has quite
addressed this area by providing an alternative means of cooking and drying.
In
a close observation, large scale cooking and drying as an drying of meat and
fish sellers, commercial corn roasters, food sellers and “suya” sellers, etc,
need efficient heating system. The absence of short drying period and hygienic
process of preserving our loide and sea foods is another issue, which has led
to fast spoiling and give an electrical stove with an oven apartment to
sufficiently address these problems.
1.3
PURPOSE OR OBJECTIVE OF THIS STUDY
This
study is to devise a means of producing an electrical stove with three
apartment to address the following:
(1)
The
problem of sooty pare-heating as observed in vaporizing cookers.
(2)
Economically,
this equipment is designed for cost reduction and easy to maintain.
(2) To reduce
the effect of kerosine scarcity prevailing in our present days.
(3)
To
meet up with inadequate availability of fire wood through deforestat6ion.

LITERATURE REVIEW
In
an extremely large span of time ago, people generally roasted by placing food
substances on hot wood coal or on heated rocks, and smoking (drying) ,of meat
and fish was done by means of brick oven. This brick oven was locally made in
a dome shape having an opening through which the firewood and other food
substances were put. In use, the firewood was burnt to a sufficient time to
provide enough hot coal before the meat or the fish already laid on a
perforated sheet or wire was regulated by either gathering the fire wood together
for more heat or withdrawing them from the oven so as to reduce the heat. This
event can be dated back at least to the third century AD
Equally
too, primitive Africans set fire on a carefully arranged fire wood and used the
fire so generated for cooking. That was when civilization was still in the
womb of time. As a result of science and technology electricity came into
during such trend that electrical element was made to generate heat when
electric current is passed through it. About 1914 electricity was adopted for
cooking, and become popular in late 1920s. along side those periods, oil
exploration and its various refined products like kerosine, gas, etc for both
industrial and domestic consumption were made possible. Hence, kerosine stores
and gas cookers, over the years, began to replace the primitive way of using
firewood for cooking and drying, particularly in most civilized regions of
Africa.
Then
came a time, late part of the last century and the new millennium, when
petroleum fuel scarcity overwhelmed the entire nation, making lives of many
Nigerians difficult. Consequently, kerosine stoves and gas cookers became n o
more alternative as before. Many Nigerians began using fire wood for cooking
and drying. This period was crucial during the PENGASAM strike, 1994. When a
certain container inside which coal is burnt to provide heat for cooking and
roasting was named
ABACHA
STGOVE: In the course of the above periods, foreign electrical stoves and
ovens flooded our local market, and their maintenance culture were by no means
easy. Thus, economically their uses were not feasible enough domestically.
Thus
threw a challenge to our local engineers to produce electrical stoves and ovens
that can stand the test of time within our locality, and to avoid the danger of
kerosine and gas explosion which have terminated a lot of lives in our present
days. Such a challenge also paved way for the project students came up with
such a dual-purpose domestic electrical heating equipment to sufficiently address
the problems being imposed by petroleum fuel consuming stoves and ovens,
incessant as stated preciously in 1.2. above.
