Development of Energy Saving Stove for Community

Abstract

The objective of this research was to develop biomass stove using agricultural residue to reduce fuel cost for farmers and to recycle waste from agriculture to fuel. The research consisted of the design of the biomass stove which modified based on the model used in the villages e.g. Khanoom Jeen making stove. The agricultural residues including husk and saw dust were tested as fuel source. The designed biomass stove was up draft flow type. The stove body was made from the mixtures of cement : sand : stone with 5 different ratios; A (3 : 1 : 3), B (2 : 2 : 3),C (2 : 3 : 2), D (3 : 2 : 2) and E (3 : 3 : 1). Plastering material was prepared from clay: husk ash at three ratios; F (1 : 1), G (2 : 1)  and H (1 : 2).  The thermal tolerant property was tested and found that the stove body with ratio B gave the best thermal tolerant at 800 ℃ for 1 hour. The three plastering ratios gave similar thermal tolerant property at 800 ℃ for 1 hour. This optimum mixture was used for making the stove with the size of 0.20 m diameter and 0.70 m height. The volume of the stove was 0.10 m³ and the average efficiency of the stove was 39.82% and this was similar to community biomass stove 40.82%.
