The Multifuel Combustion System and the Peko PeThe Peko Pe stove was developed 1990, and first utilized in Adjumani North of Uganda in refugee camp in 1995 using bundles of straw and papyrus as fuel. And there the stove was given the name Peko Pe, which means in the language of the Acholi tribe approach to “no problem”. The reason, the women did not need to go into the forest to collect firewood, which was dangerous those days. With one kg of straw one could easy make a meal for a small household. And there was no smoke and little soot.Afterwards the stove is justified and is now burning with a clear blue yellow flame at about 700°C with almost all types of dry combustible biomass and with no smoke, no soot and no dangerous gases.The stove also called the energy unit is the heart of the Multifuel Combustion System, MFCS. With one unit you can prepare a small meal, with two units make it more convenient to cook and with three or more units you will cower all needs of energy at the household and institutional kitchens sector. It is a flexible simple system it can be used for baking, frying, grilling, wok, smoking fish, heating air and water-heating, takeaway food business and which will cover all needs of energy at the sector. The fuel can be all kind of combustible dry adapted biomass. The design of the energy unit is based on simple combustion principals, which has to be followed strict to avoid smoke and soot. More or less the stove is a small charcoal kiln, which utilize the combustible gases, which normally disappear for nothing in a common charcoal kiln. This energy represents about 80% of the total energy into the wood used by the process of making charcoal. And that’s why about 2/3 of the fuel-wood will be saved by using fuel-efficient stoves like the Peko Pe compared to the use of charcoal and wood on 3stone fireplaces. The stove (energy unit) can be produced by a local tinsmiths with simple hand-tools out of any kind of metal sheets The usage of the stove is simple and all types of utilities can be used on the stove. One unit will burn with flame about 50 minutes with 1kg chipped wood and by utilize the charcoal effect when flame is over, you will have a time of cooking for about 2 hours more. That means it is possible to boil 1kg of beans with 1kg of woodchips. By using more units together you will easy cook 60 litres of water for about 3 hours with 7-8 kg of woodchips. There has to be more focus on alternative biomass fuel. Charcoal is in some aspects an efficient fuel, but seen from the Miombo forest point of view it is expensive and exploiting To make one kg of charcoal you need 8kg of dry wood and a household of 5 persons need 2 ½ kg Charcoal per day, and in addition 70-80% of the energy is lost in the stove. It will also give some dangerous CO gases. The temperature from the glowing will normally be too high, so by boiling beans you constantly have to ad cold water, which then prolong the time of cooking. Combustible biomass is more than wood and charcoal. Treated the right way, all types of forest and agriculture residues, all types of milling left over, straw, grass, reeds. Chipped wood, twigs, maize cobs; biomass briquettes, pellets, peals, nutshells etc can be excellent fuel and household energy But an efficient adapted infrastructure for production, transport and sales is necessary. Biomass is sustainable fuel, and by utilizing it the right way into fuel-efficient stoves with complete combustion, you will solve a lot of problems. Save the forest, save the environment, reduce smoke related deceases, create new jobs, and create more energy.
