Abstract

This study investigated the higher heating values, lower heating values, bulk density, energy density, and latent heat of vaporisation characteristics of paunch. The higher heating values (gross calorific value) were 16.9 and 20.3 MJ kg-1 for grass and grain type paunches respectively. Bulk density ranged from 106 to 587 kg m-3 for dry to wet untapped paunch, and 152.04 to 884.64 kg m-3 for dry to wet tapped paunch. The energy density values for paunch varied from 4865 to −2110 MJ m-3. The latent heat for paunch varied from 3741 to 2519 kJ kg-1 for 6 to 15% moisture content (MC) with the average latent heat of vaporisation for paunch found to be 2842 kJ kg-1. These values show that paunch has the potential to be a useful waste-to-energy stream for implementation into industry and will help inform future paunch drying designs.
