Biogas is a kind of bio-fuel that occurs naturally as a result of the decomposition of organic
waste. When organic matter, including food waste and animal waste, decomposes in an anaerobic
(oxygen-free) environment, it releases a gas mixture, mainly methane (50-80%) and carbon dioxide
(20-50%).This document describes the combustion behavior of home-made Porous Radiant Burner
(PRB) used in industrial crematoryas well as bio-medical solid waste dumped systems. PRB is mainly
designed to work in the range of 5-10 kW firing rate, which is a two sided -layer porous environment
technique. Three kinds of burners namely convergent (60mm), straight (70mm), and divergent (80mm)
are considered for experiment. The burner contains two zones (i) combustion zone, and (ii) pre-heating
zone. Sic foam of 10 ppi with 25mm stiffness and steel balls (6.5 mm each) acts as combustion zone
and pre-heating zone respectively.From experiments, better efficiency is attained using the newly
designed PRB.This is performed by varying the equivalence ratio (ϕ) between 0.10 and 0.60 in a
constant operating range.The 59.92% burner operating range is the maximum efficiency analyzed for
a PRB with a diameter of 80 mm and a 0.16 equivalent ratio of 0.55 kW.
