N2 - This paper presents results from water boiling tests on the pyrolysis gasifier stove Peko Pe, which has been developed by the Norwegian Paal Wendelbo. The stove efficiency determined vary between 21 and 29% when burning dry Danish woodchips (10% moisture) with an estimated caloric value of 16 MJ/kg. CO-emissions have been determined with varying distance between the stove and the pot to estimate the combustion efficiency. Efficiency tests performed in Adjumani refugee camp with grass as fuel show a stove efficiency of 25-29% with a caloric value of 14 MJ/kg. It has not been possible to determine the water content in the grass. In Adjumani refugee camp it was furthermore found that the stove was able to provide sufficient energy from solid combustion, after the pyrolysis was stopped, to boil water for additional 25-30 minutes with lid. This effect was not seen in the tests on woodchips in Denmark. Advantages and disadvantages of the stove compared to three-stone stoves are discussed and perspectives are outlined for further improvements of the stove.
