The present study was undertaken with the objectives to develop a filter system for a 20 kW engine application and to test the filter. It was observed that tar content in the gas ranged from 12.4 to 85 mg/m3 , which was considered on the higher side, in some cases, compared from an accepted limit of 50 mg/m3 . The 20 kW cleaning and cooling system for cleaning of producer gas was developed by calculating the gas flow and maximum retention time in the filter. The diameter of these three filters, viz., water scrubber, wet filter and dry filter was calculated from retention time and velocity in the filter, which was found to be 0.20, 0.40 and 0.50 m respectively, with filter height of 0.80 m. The developed filter was evaluated for reduction of tar in the producer gas after cleaning. The tar content in the producer gas after filtration by using the system varies from 24 to 53.52 mg/m3 . The tar absorption using this filter system was 99.35%, while the pressure drop varied between 10 to 25 mm of the water column. The system was also operated by coupling with a small capacity IC engine. The diesel replacement was found to be in the range of 65.66 %.

This work is the analysis of the energy generation of a 2 MW wind power project installed at Motha, District Amaravati, in the state of Maharashtra. The various availabilities of the wind power project were studied for the efficient energy production of the project. It was observed that 92.72 percent of the system was available for energy generation throughout the year. The energy generation data with the various shutdowns of the system was studied. The energy generation of the system was studied in terms of the plant load factor or the capacity factor. Capacity factor was observed to be 21.16 percent with the total energy generation unit being 3.73 MWh.

The present research work assesses the bioenergy available in a rural village for self-sustainable development. The biomass consumption of the village for domestic as well as for all the activities has been collected. The study also entailed the collection of all bioenergy sources available in the village. The bioenergy sources, such as biomass available through forestry, agriculture waste and residues etc., and animal waste (animal dung), have been collected for the exact quantification of the bioenergy generation capacity of the village. From the study it has been found that the village has considerable bioenergy potential. The magnitude of the bioenergy density will help in achieving a self power-generating village. The bioenergy density will also help for the development of a bioenergy atlas for the particular location. A suitable renewable energy generation system in the studied village is being recommended.
