Husk availability; rice husk gasifiers; financial feasibility; unit cost of electricity; rice mill; paddy parboiling
Rice husk generated as a by-product of rice processing is an important energy resource. The
availability of this resource in India has been assessed and the technologies for exploitation of its energy potential in rice processing industry discussed. Nomographs have been developed for estimation of the husk required to meet the energy demand of parboiling, drying and milling operations. The unit cost of
electricity using rice husk gasifier-based power generation systems has been calculated and its financial feasibility assessed in comparison with utility-supplied and diesel-generated electricity. With the cost and efficiency data assumed here, the unit cost of electricity produced by rice husk gasifier-dual fuel
engine-generator system varies between Rs Z/kWh and Rs 7/kWh.
