Performance of Open Core Gasifier with Briquette of different Crop Residues

The open core gasifier was designed for loose agricultural residues like soybean briquette, pigeon pea briquette and mix briquette of (soybean + pigeon pea). In this experiment using air in gasification as supplementation mode there result found better as air suction mode there was less tar and gas quality. The gasifier performance was evaluated in terms of fuel consumption rate, calorific value of producer gas and gasification efficiency. Optimum value of specific gasification rate for gasification of briquette of mix biomass in open core gasifier reactor is 252 kg/h- m2 . The lower heating value of producer gas under the optimum operating conditions is about 4.10 - 4.57 (MJ/m3 ).The pigeon pea briquette has show the maximum temperature in oxidation zone was 1397 ˚C.which as higher the ash fusion temperature increase. The flame Temperature of soybean briquette, pigeon pea briquette, and mix briquette is 624, 634, and 619 ˚C respectively is attained at the burner.
