The behaviour of an updraft moving bed gasifier of diameter 76 mm and height 787 mm, with rice husk as a fuel, has been studied. The gasification rate of the rice husk was varied in the range of 3.5-12.5 x 10(-3) kg/m2 s. The air velocity was varied in the range of 0.07-0.11 m/s. The producer gas obtained from the gasifier has a calorific value in the range of 3712-4464 kJ/m3. A set of theoretical kinetic equations on the assumption of nonequilibrium conditions has been developed and solved numerically. The simulated temperature profile and outlet gas composition have been compared with those obtained from experimental runs. This model, which is developed from a mechanistic approach, can appreciably explain the behaviour of the present system within the range of variables studied.
