Abstract:
This paper presents useful energy (gas and power) production from the
three waste biomass (dried grass, leaves, and dead branches) through gasification
technology. These waste biomasses were collected in the Indian Institute of Technology Ropar, Punjab and air-dried. The feasibility of the studied biomass for thermochemical conversion process in a downdraft biomass gasifier has been investigated by characterization of biomass. The average higher heating values based on
the ultimate and proximate analysis correlation were evaluated as 15.58 MJ/kg for
dried grass, 17.075 MJ/kg for leaves and 15.785 MJ/kg for dead branches. The performance of downdraft biomass gasifier has been investigated in terms of calorific
valve (3.52 MJ/m3 for dried grass, 5.14 MJ/m3 for leaves and 4.15 MJ/m3 for dead
branches) and cold gas efficiency (50.83%, for dried grass, 64.72% for leaves and
59.15% for dead branches). The results show that these waste biomass are a reliable
source for energy production through gasification technology having dual benefits
of easy waste management and low-cost power production.
