Today, the most promising version in stove design is the '
Ceramic Jiko' (KCJ). Kenya
The KCJ is a portable stove that uses charcoal as fuel. Shaped like an hourglass, the metal stove has a ceramic lining in its top half, with the bottom half being a collection box for ashes. The coals are placed into the ceramic lining at the top, which is perforated to let the ashes from the coals fall to the bottom of the stove. These ashes can then be collected and disposed of safely. The head of the stove has metal rings that hold a pot in place for cooking.
The KCJ increases stove efficiency by addition of a ceramic insulating liner (the brown element), which enables 25 to 40 percent of the heat to be delivered to the pot. From 20 to 40 percent of the heat is absorbed by the stove walls or else escapes to the environment. In addition, 10 to 30 percent gets lost as flue gases, such as carbon dioxide. With proper use and maintenance, the KCJ has been shown to reduce fuel use by 30 to 50%. This means less wood is burned to make charcoal, and fewer trees have to be cut down. This also means less labor in looking for and chopping firewood. The stove also reduces emissions from incomplete combustion, such as toxic gases and particulate matter, resulting in better overall health of the users.
The Kenya Ceramic Jiko was designed through efforts of local and international agencies and many concerned people. Today, the stove is so popular that it is used in over 50% of all urban homes and about 16% of rural homes in
. Furthermore, its use has now spread to neighboring African countries, and variations of the KCJ can now be found in homes in Kenya Uganda, Rwanda, Ethiopia, Malawi, Niger, Senegal, and . Aside from KENGO, several NGOs, including CARE ( Sudan ), have worked with women's and community groups on the production, demonstration and dissemination of the stoves. Kenya
Prerequisites: The use of the stove requires access to fuelwood or charcoal. Production of the stoves requires ceramic material and scrap metal. Training has been provided by KENGO to other regional NGOs in the manufacture of the new jiko. Quality control is an important factor in maintaining the improved efficiency of the stove.
Cost and availability: The trade name of the new domestic jiko is Kimathi Jiko, and it sells for 55 to 75 Kenyan shillings, or Can $2 to $3.
