Brief Description
Description : | The developed gasifier reactor with L/D ratio (Length to Diameter of gasifier) of 10 has been adopted to improvise the mixed flow and plug flow reactor characteristics to ensure full suspension of powdery biomass/coal in a vigorous radial mixing condition in the reactor and to achieve high intensity reaction and gasification which are essential for entrained flow gasification. Based on the simple plug flow characteristics, a gas residence time of about 2 second has been adopted for the gasifier. The gasifier-reactor attains a temperature in the range of 900-1200 °C to take the advantages of the kinetics of the process and produce low tar and char formation. By maintaining a pre-estimated Equivalent Ratio (ER) of 0.2Technology Demonstration, temperature of the partial oxidation can be varied as per requirement. The endothermic steam induced reactions with a steam injection coupled with the gasification reactions conserves the sensible process heat in the form of more hydrogen and carbon monoxide. |
