Most of the energy consumed worldwide comes from non-renewable sources, such as oil derivatives, making it necessary to search for renewable, clean energy sources, with emphasis on biomass from agricultural and industrial waste. Coconut shell pellets (CSPs) and cashew nut shell pellets (CNSPs) were manufactured and subsequently subjected to chemical, thermal and exhaust gas analyses of their combustion. Mean temperature results in the combustion area were 366.44 ± 84.79°C (CSPs) and 295.00 ± 89.47°C (CNSPs). The exhaust gas combustion values were 19.43 ± 0.57% (CSPs) and 18.75 ± 0.77% (CNSPs) of O₂, 2348 ± 1241 ppm (CSPs) and 2901 ± 499 ppm (CNSPs) of CO, 14.92 ± 5.06 ppm (CSPs) and 39.83 ± 10.91 ppm (CNSPs) of NO_x, and 441.25 ± 130.41 ppm (CSPs) and 2841.50 ± 765.26 ppm (CNSPs) of CH₄. In conclusion, the combustion process of CSPs proved to be less polluting and more energy efficient when compared with CNSPs. The analyses of the exhaust gases from the combustion of these biomasses can serve as a basis for the creation of safety parameters and public policies to regulate the use of biomass for energy purposes.

全球消耗的大部分能源来自石油衍生物等不可再生能源，因此有必要寻找可再生的清洁能源，重点是农业和工业废物中的生物质。制造椰子壳颗粒 (CSP) 和腰果壳颗粒 (CNSP)，然后对其燃烧进行化学、热和废气分析。燃烧区域的平均温度结果为 366.44 ± 84.79°C (CSPs) 和 295.00 ± 89.47°C (CNSPs)。废气燃烧值为 O ₂的 19.43 ± 0.57% (CSPs) 和 18.75 ± 0.77% (CNSPs)，CO 的2348 ± 1241 ppm (CSPs) 和 2901 ± 499 ppm (CNSPs)，14.92 ± 5.06 ppm (CSPs)和 39.83 ± 10.91 ppm (CNSP) 的 NO _x和 441.25 ± 130.41 ppm (CSP) 和 2841.50 ± 765.26 ppm (CNSP) 的 CH₄ . 总之，与 CNSPs 相比，CSPs 的燃烧过程被证明污染更少，能源效率更高。对这些生物质燃烧产生的废气的分析可以作为制定安全参数和公共政策以规范生物质用于能源目的的基础。
