Development of Integrated Energy System for a Goshala Complex (Intensively Live Stocked Farm)

Abstract

A study was carried out to assess the energy demand and resource availability in goshalas (Intensively Live-stocked Farm) and to suggest appropriate integrated model. Survey was carried out in three goshalas (small, medium and large) of district Hisar, Haryana. The assessment of thermal, mechanical, electrical and human energy demand in the goshalas was made. The availability of resources in the goshalas was also determined. Thermal, mechanical, electrical and human energy demand per animal per day was 0.668 MJ, 0.099 MJ (0.36 hp-hr), 0.204 MJ (0.056 kWh), and 0.432 MJ respectively. The average dung availability per animal per day was 4.28 kg. For economic analysis two arbitrary goshalas having cattle head population of 600 and 1200 were chosen. Four models viz. Model-I consists of the goshalas without biogas plant and biomass gasifier, Model-II consists of the goshalas with biogas plant, Model-III consists of the goshalas with biogas plant and vermicomposting unit, Model-IV consists of the goshalas with biogas plant, vermicomposting unit and biomass gasifier for both the goshalas were developed and the economic evaluation was carried out. The Model-I and Model-IV were found to be uneconomical for both the goshalas. The Model-III was found to be more economical as compared to Model-II. Therefore, Model-III was suggested for both the goshalas to make them self-sufficient in energy.
