Abstract
Biomass gasification is a thermo chemical process, which converts the solid
biomass in oxygen deficient environment into combustible producer gas. The cotton
stalk is abundantly available for converting solid biomass into useful form of energy,
gasification is receiving prime importance. Downdraft gasifiers have promising potential
for agriculture and agro industrial applications, which provided improved gas quality,
particularly in terms of tar and particulate matter contents of the gas.
In the present study, a open core throatless downdraft gasifier has been designed
and developed. The performance of the developed gasifier is made by using shredded
cotton stalk as feed stalk. The fuel properties of cotton stalk and its gasification for open
core throatless downdraft gasifier were investigated. The whole cotton stalk plant is
converted into shredded material with the help of cotton stalk shredder. The capacity of
cotton stalk shredder machine is 218 kg/h.
The proximate analysis of the shredded cotton stalk in terms of moisture content
(13.63 %, db), voladle matter (74.52 %, db), ash content (4.95 ^b), fixed carbon
(20.53 /o) and calorific value of cotton stalk biomass (3827 cal/g) were determined.
