ThesisItem Open Access Design, Development And Performance Analysis Of Bio-Syngas Fuelled Cookstove Burner(MPUAT, Udaipur, 2023) Anshul Paliwal; B.L. SalviBio-syngas, also known as biomass syngas, is an innovative and sustainable energy option derived from the gasification of biomass. This study presents an experimental analysis of the performance and cost effectiveness of a developed burner designed for utilizing bio-syngas as a cooking fuel. The research focuses on optimizing the burner design to accommodate the unique characteristics of bio-syngas. The results indicate that the air fuel ratio for bio-syngas is significantly lower (1.39) compared to LPG (15.8). As a consequence, the primary air requirement for the bio-syngas burner is negligible, leading to a design modification where the primary air port is closed. Different burner heads with varying port diameters (2-6 mm) were tested to determine the most suitable configuration for bio-syngas. Through performance analysis, it was observed that the burner setup with a port diameter of 4 mm achieved the highest thermal efficiency (42.48%) at a low bio-syngas flow rate of 10 LPM. At higher flow rates (20, 25, and 30 LPM), the burner setup with the respective port diameters performed optimally with thermal efficiencies of 36.02%, 35.77%, and 41.74%. The study recommends using the burner setup with a 2 mm port diameter for community cooking, typically performed at high flow rates. Conversely, for household cooking, which is usually carried out at lower flow rates, the burner with a 4 mm port diameter is recommended. The research also delves into the cost economy of bio-syngas production, considering factors such as electricity, wood, chipping, and labour costs. The calculated cost of bio-syngas per cubic meter is approximately Rs 5.7, while the equivalent cost of LPG is around Rs 150 per cubic meter. A comparative case study was conducted for a family of four to analyze the cost effectiveness of using bio-syngas over LPG. After comparing the energy equivalent costs, it was found that utilizing bio-syngas results in early savings of Rs 875 for the family. Moreover, the use of bio-syngas does not contribute to greenhouse gas emissions, making it a more environmentally friendly cooking fuel alternative to LPG. In conclusion, this study demonstrates the potential of bio-syngas as a sustainable and cost-effective cooking fuel. The optimized burner design enhances the utilization of bio-syngas, leading to significant thermal efficiency gains and economic advantages. With its environmentally friendly attributes and promising cost effectiveness, bio-syngas presents a viable option for clean and efficient cooking applications.
