Rancang Bangun dan Evaluasi Kinerja Kompor Briket Tandan Kosong Kelapa Sawit

Abstract

Design and construction of biomass stove using empty oil palm bunches (EFB) briquettes as renewable alternative energy for households and as a substitute for fossil fuels whose availability is decreasing. This briquette stove is designed with a primary air hole of 132 mm and a secondary air hole of 12 mm, using EFB briquettes as fuel with a calorific value of 5,993 cal/g. The method used to determine the performance of the briquette stove is the Water Boiling Test (WBT) with 2 variations of air supply, natural draft and using a fan with an air speed of 2 m/s. The results of the performance test of this briquette stove obtained data on fuel consumption specifications, flame time, and thermal efficiency. In test 1 with a natural draft air variation, the results for specific fuel consumption were 0.8338 Mj/hour, flame time 2 minutes, thermal efficiency 10.50% and in tester 2, specific fuel consumption was 1.2507 MJ/hour, flame time 30 seconds, thermal efficiency 10.92%. The test results showed that sufficient air supply during combustion can increase the flame time and thermal efficiency.
