Abstract

This work presents a design of high efficiency downdraft  gasifier. The hight, throat diameter, diameter and size of stove were designed in order to the product gas. The volume control of air, oxygen and steam  were also studied in order to increase the efficiency of the gasifier. The steam system was designed by using the heat recovery from the gasifier . From the study, it was found that the gasifier has the capacity of  34 kw with the  fuel feed rate of 15 kg/hr. The hight of the gasifier was 166 cm, and the diameter of stove, throat, and air pipe were 44 ,13.80, 1.56 cm, respectively. From the calculation, this system can produce steam at 13.84 kg/hr and is require oxygen and air equal to 2.68, 13.99 m3/hr, respectiovely. The efficiency of the designedt downdraft gaifier was 29.60% higher than that of conventional gasifier.
