N.S. Rathore, N.L. Panwar, Y.V. Chiplunkar

Abstract


This paper addresses the design, performance and economic evaluation of biomass based open core downdraft gasifier for industrial process heat application. The gasifier is having feed rate as 90 kg h-1 and producing about 850 MJ h-1 of heat. The gasifier has been installed in M/S Phosphate India Pvt. Limited, Udaipur (27° 42' N, 75° 33' E) for heating and concentrating phosphoric acid. The system is in position to save 20 L of light diesel oil per hour. The techno economics of the designed system is also presented in the paper.

Key words: Biomass, gasifier, downdraft, feed stock.
