Abstract

This study is focused on development of burner and utilization of biosyngas as green fuel for cookstove. The biosyngas was produced from waste biomass using downdraft gasifier. A commercially available self-aspirated cookstove burner (0.5 to 2.0 kW) for liquefied petroleum gas (LPG) was modified to operate with biosyngas as green fuel. The different burner heads with varying port diameters (2.0 to 6.0 mm) were developed and gas nozzle diameter was changed from 1 mm to 2 mm. Then experimental study was carried at different flow rates (10 to 30 LPM) of biosyngas. The maximum burner efficiency was found 43.2 % with 2.0 mm port diameter and gas flow rate of 30 LPM for community cooking; while for household cooking the burner with 4.0 mm port diameter and flow rate 10 LPM was found with burner efficiency 43.1 %. The biosyngas as green fuel is environment friendly and based on a case study; it was found that replacement of LPG by biosyngas offers cost savings of INR 576.0 per family (4 members) per year and saving of 0.4436 tons of CO₂ emission per year per family. The cost saving, about 4 % of yearly expenditure on LPG per family per year, may not be more appreciable, but biosyngas is renewable in nature and net CO₂ addition to the environment is zero. Therefore, burner optimization is required for different applications and biosyngas can be used for community cooking as green fuel for sustainable energy system.

面向可持续能源系统的生物合成气绿色燃料改性炉灶燃烧器的研制与性能研究

本文对生物合成气作为绿色燃料的燃烧器的开发和利用进行了研究。利用下吸式气化炉从废弃生物质中生产生物合成气。改造了一种用于液化石油气（LPG）的市售自吸式炉灶燃烧器（0.5至2.0 kW），使其可以使用生物合成气作为绿色燃料。开发了不同喷嘴直径（2.0 ~ 6.0 mm）的燃烧器头，燃气喷嘴直径从1 mm变为2 mm。然后对不同流量（10 ~ 30 LPM）下的生物合成气进行了实验研究。当炉口直径为2.0 mm、燃气流量为30 LPM时，用于社区烹饪的燃烧器效率最高为43.2%；家用烹饪用燃烧器孔径为4.0 mm，流量为10 LPM，燃烧器效率为43.1%。生物合成气作为绿色燃料是环境友好的，基于实例研究；研究发现，用生物合成气取代液化石油气，每户家庭（4名成员）每年可节省576.0印度卢比的成本，每户家庭每年可节省0.4436吨二氧化碳排放。节省的成本，大约是每个家庭每年LPG支出的4%，可能并不明显，但生物合成气本质上是可再生的，并且对环境的净二氧化碳排放量为零。因此，需要针对不同的应用对燃烧器进行优化，生物合成气可以作为可持续能源系统的绿色燃料用于社区烹饪。
