Biomass is a renewable energy source derived from plants and is known as green energy. Biomass is a term used for various types of organic matter in solid form that can be used as fuel. Bio Briquette is a solid fuel made from a mixture of biomass. This fuel is an alternative material that was developed in a bulk with relatively short time and is relatively cheaper. The use of briquettes that must be included with the use of a stove or stove which type and size must be adjusted to the needs. To increase the heat efficiency of the existing briquette stoves, this research was carried out using two different types of stove walls, namely cement-filled stoves and glass wool-filled walls. The performance of the stove can be seen from the combustion of biomass briquette fuel against the briquette shape was molded. From the tests that have been carried out, the efficiency of stoves with cement walls is 29.86%, while for stoves with glass wool walls is 40%. Of the three forms of bio briquette (ellipsoidal, cylinder, perforated cylinder) the use of cylindrical bio briquettes is better because the flame on the briquette is longer when compared to other forms.

生物质是一种源自植物的可再生能源，被称为绿色能源。生物质是用于固体形式的各种有机物的术语，可用作燃料。生物煤球是一种由生物质混合物制成的固体燃料。这种燃料是一种可替代的材料，可在相对较短的时间内大量开发并且相对便宜。煤球的使用必须包含在炉子中，或必须根据需要调整炉子的类型和大小。为了提高现有型煤炉灶的热效率，这项研究是使用两种不同类型的炉灶壁进行的，即水泥炉灶和玻璃棉炉灶。炉子的性能可以从生物质型煤燃料的燃烧过程中看出来，反对成型的型煤形状。根据已经进行的测试，水泥墙炉灶的效率为29.86％，而玻璃棉墙炉灶的效率为40％。在三种形式的生物团块（椭圆形，圆柱，多孔圆柱）中，圆柱形生物团块的使用效果更好，因为与其他形式相比，团块上的火焰更长。
