SECTION 1



STOVES




A Stove is a self-contained appliance that
may be used for heating or cooking or both.

Stoves differ from open fires in that they
are easier to control, more efficient and
may create less pollution.

MASONRY
HEATERS




Masonry heaters were developed to control air
flow in stoves. A masonry heater is designed
to allow complete combustion by burning fuels
at full-temperature with no restriction of air
inflow.

Due to its large thermal mass the captured heat
is radiated over long periods of time without
the need of constant firing, and the surface
temperature is generally not dangerous to touch.

COOKER
COOKSTOVE




A cooker (or cookstove) is an appliance,
device or apparatus designed solely for
the purpose of cooking food. Cookers rely
on the application of direct heat for the
cooking process and may also contain an
oven, used for indirect heating (baking).

Cookers (and the term) have evolved over
time.

KENYA
CERAMIC
JIKO
KCJ




The Kenya Ceramic Jiko (KCJ) has been the
most widely accepted to date, having become
a standard item in most homes in Kenya and
neighboring countries in East Africa.

Charcoal is the standard cooking fuel in East
Africa. Traditionally it was burned in a metal
stove or “Jiko” as stoves are called in the
Swahili language.

The KCJ is simply the traditional Jiko mated
to a ceramic liner, producing a stove that is
at least one fourth (and up to 50%) more
efficient than traditional all-metal alternatives,
costing only $2 to $5.

It has a distinctive shape, differing from the
traditional cylindrical jiko, with the top and
bottom the same diameter, tapering at about 30
degrees to a waist.

LORENA
ADOBE
STOVE




The Lorena adobe stove was designed as a
simple-to-build cook stove for use in
Central America, one that could be
manufactured locally of local materials.

It became very popular in Central America,
with anecdotal evidence suggesting that it
is the most popular improved cooking stove
in the region.

The Lorena stove is an enclosed stove of
rammed earth construction, with a chimney
built onto it.

IMPROVED
LORENA
JUSTA
STOVE




The Improved Lorena or Justa stove has
a sealed metal cooking surface that sits
above a stove made of bricks, and a
chimney that carries the smoke outside.

The Improved Lorena stove is a simple
biomass stove built around an insulated,
elbow-shaped combustion chamber which
provides more intense heat and cleaner
combustion than an open fire, meaning
that it consumes less fuel then a 3 rock
stove, removing smoke from the house.

FUEL
CONSERVATION




Standard approaches
to conserving
cooking fuel;


There are three places
in the cooking process
where fuel can be
conserved;

the fuel,

the stove,

the cooking pot.


The greatest gains come not from the stove
itself, but from how the heat the stove
produces is used; paying attention to the
pot rather than the stove results in the
greatest fuel savings.

In fact, fuel efficiency in a stove is
usually much more affected by heat transfer
to the pot than it is by improving combustion
efficiency.


The first way to reduce the amount of fuel a
family consumes is simply to use a cooking lid
while cooking, which by itself reduces fuel
consumption by 40%.
This simple change will normally save more fuel
by itself than switching to an improved stove.


The second strategy is similar to the first;
use a larger cooking pot.
Larger pots are more energy efficient than
smaller ones and wide shallow pots are more
efficient than tall narrow ones.


Last, when cooking for a family, switching from
a stove that has room for only one pot to cook
at a time, to a stove where two or more pots can
cook at once will often raise efficiencies by up
to 40%.


In developing countries, families who rely upon
wood for cooking have three ways of obtaining it.
They can scavenge the areas where they live for
firewood, purchase it from a firewood dealer, or
grow their own.

ROCKET
STOVE




A rocket stove is an innovative clean and efficient
cooking stove using small diameter wood fuel which
is burned in simple high-temperature combustion
chamber containing an insulated vertical chimney
which ensures complete combustion prior to the
flames reaching the cooking surface. The principles
were described by Dr. Larry Winiarski from Aprovecho
in 1982 and stoves based on this design won Ashden
Awards in both 2005 and 2006. Interest in rocket
stoves has led to the development of rocket mass
heaters and other innovations.

A rocket stove achieves efficient combustion of the
fuel at a high temperature by ensuring that there
is a good air draft into the fire, controlled use
of fuel, complete combustion of volatiles, and
efficient use of the resultant heat. It has been
used for cooking purposes in many third-world
locales (notably Rwandan refugee camps) as well
as for space and water heating.



A rocket stove's main components are:


Fuel magazine:

Into which the unburned fuel is placed and
from where it feeds into the combustion
chamber


Combustion chamber:

At the end of the fuel magazine where the
wood is burned



Chimney:

A vertical chimney above the combustion chamber
to provide the updraft needed to maintain the
fire



Heat exchanger:

To transfer the heat to where it is needed,
i.e. the cooking pot.
