Paddy straw based energy generating biogas plant made up of mild steel

Abstract

The main objective of this research is to produce biogas from paddy straw collected from the field. The biogas produced by dry fermentation in the absence of oxygen. A new design of leakage proof digester is made up of mild steel is developed. This digester is placed on the ground, so that it remains in the contact of sunlight directly. For production of biogas high temperature and leakage proof system is favorable. Sunlight increases the fermentation and provides high temperature. The size of digester is 6feet diameter x 6.6 feet height. The capacity of digester is 460 kg paddy straw chopped husks mixed with 150 kg cattle dung. This composition of paddy straw and cattle dung produced biogas for regular three months. In this research the production of biogas is measured and this biogas produced is equivalent to 3 LPG cylinders.
