Design of Biomass Briquette Stoves: Performance Based on Mixed of Durian Bark, Coconut Shell and Palm Shells as Materials of Bio Briquette

Abstract

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.
