ANALYSIS OF CALORIFIC VALUE OF ANIMAL MANURE BY MAKING FUEL PELLETS OF DIFFERENT COMPOSITES

Mechanical Engineering

Every year millions of tons of agricultural and animal waste are generated which are either destroyed or burnt inefficiently in loose form causing air pollution. The use of agricultural and agro-industrial waste as biomass fuel for power generation like briquettes or pellets can be an alternative solution to the problems related to their disposal & pollution. Clean and dry residue pellets are an ideal fuel for combustion in small scale installations. This project aims at finding the best substitute of wood, so that it can be eco-friendly. In this project we have tried to make pellet machine aiming to frequent generation of pellets and also tried to generate different composites of different biomass materials to make manure pellets by using biomass materials like wheat straw, dry leaves, groundnut shell, rice husk, saw dust and animal manure. After preparing pellets, we let them dry completely in sunlight. Then the analysis of the calorific value of pellets produced of different composition is done by determining their fixed carbon percentages. At last, the calorific values of prepared pellets are compared with the calorific value of wood.
