Investigation on gasification of shredded cotton stalk was carried out by developing an open core throat less downdraft gasifier reactor (capacity: 70 MJh-1). Performance of the gasifier was carried out at six different gas flow rate (12, 14, 16, 18, 20 and 22 m3/h) levels. The gasifier performed best at 18 m3h-1 gas flow rate with equivalence ratio, gasification efficiency, specific gasification rate, specific gas production rate and fuel consumption rate of 0.35, 71.05 %, 192.51 kgh-1m-2, 481.28 m3h-1m-2 and 7.2 kgh-1 respectively. The economic analysis was carried out by considering shredded cotton stalk as feed stalk and compared with briquette. The benefit cost ratio of the gasifier system was increased from 1.45 to 2.18 (50.34%) and payback period decreased from 5y 9m to 3y 5m (40.39 %) considering shredded cotton stalk as feed stock and compared with briquette for (gas flow rate: 18 m3h-1, daily operation: 20 h per day) 270 days of operation per year.
