Design of Biogas Stove for Frying Chips and Effective Utilization of Cashew Nut Shell for Gasification

Abstract

This study mainly focuses on the waste minimization, the effective utilization of biogas that is generated from anaerobic digestion of banana peel waste and the effective utilization of cashew nut shell for gasification. The OS Chips company located in Selvapuram, Coimbatore has been selected for the study. The company has installed a biogas plant utilizing banana peel waste as a feed material. In order to use the biogas for thermal applications like frying chips, normal stoves cannot be used. Hence a stove utilizing biogas as fuel has been designed. The cashew nut shell that is used as a fuel in the company has been tested for its effectiveness in gasification process. The cashew nut shell contains a large proportion of volatile content (78%) and low ash content (2%) which proved its effectiveness in the gasification process.
