2.1. Biomass for testing
Babul wood (Prosopis juliflora) was selected as feedstock for testing of wood gas stoves. The babul wood was cut into small pieces as mentioned in Table 1 and stored in a dry place for further use. Proximate analysis of fuel was carried out before the test by using the method suggested by ASTM [21]. The calorific value of feedstock was also measured by a digital bomb calorimeter (Advance Research Instrument Company). The physical and thermal properties of feedstock used for testing purposes are given in Table 1
