Experimental investigation of open core downdraft biomass gasifier for food processing industry

Original Article


This paper deals with field related experience of a low temperature industrial heat application through biomass gasification. The gasification system is essentially consists of an open top down draft reactor lined with ceramic. The experiment reveals that 6.5 kg of liquefy petroleum gas (LPG) is fully replaced by 38 kg of sized wood on hourly basis. The maximum temperature attained was 367°C in 130 min at 100.7 Nm3 h−1 gas flow rate. This system has resulted a saving of about 19.5 tons of LPG over 3,000 h of operation, implying a saving of about 33 tons of CO2 emission, thus a promising candidate for clean development mechanism. Fuel economic analysis of gasifier system showed that the saving was about 13,850 US$ for 3,000 h of baking operation.
