The growing demand for alternative energy sources has furthered the interest on biomass over the last decades. Thus, a hydrodinamic study of conical spouted beds equipped with draft tube has been carried out for biomass, specifically, chickpeas. Runs have been carried out in conical spouted beds of different geometry following a design of experiments. Solid cycle times (average, maximum and minimum) and circulation mass flowrates have been measured in draft tube conical spouted beds for different geometric factors of the contactor (angle and gas inlet diameter), draft tubes (diameter, height of the entrainment zone and width of the faces) and under different operating conditions. The results show that solid cycle times and circulation mass flowrates are highly dependent on the type of draft tube and contactor angle.
