Abstract

Identification of efficient fuelwood.

Abstract

Seven species commonly used for fuelwood by farmers in the villages of Sirsi taluka, Karnataka, were tested for efficiency by estimating the weight of wood and time required to boil 5 litres of water in an aluminium vessel with a lid on, on an ordinary Chullah (cooking stove). The least wood consumption was by Acacia auriculiformis (0.727 kg), followed by fronds of Cocos nucifera (0.892 kg; an agricultural waste). The least time was taken by Kartinaragum domentorum (Randia spinosa) (16 min) followed by fronds of Cocos nucifera (21 min) and Macaranga peltata (22 min). The other species tested were Xylia xylocarpa, Casuarina equisetifolia and Trema orientalis. Burning characteristics of the species are also noted.
