Abstract

Along with the development of industrial technologies is rapidly increasing the demand for renewable energy sources becomes a very important consideration. One of the alternative energy is now being developed is the energy derived from organic materials, this is because the organic compounds are classified as renewable energy. One energy technology in accordance with the requirements of the biogas technology. If biogas is purified or cleaned of impurities in this case CO2 is good, he would have the same characteristics as natural gas. How big is the influence of CO2 on heating value (heat) in the combustion process it is necessary to an investigation. one by looking at the characteristics of combustion, both the pattern and pace of rambatnya. Combustor used in this study is a model of Helle-shaw cell measuring 50 x 20 x 1 cm. Variation of the mixture used is the ratio 7,5:1 to 10: 1 with the addition of 10% 20%, 30% CO2. Performed on the ignition of ignition. Observation of the shape and rate of flame propagation is done using a high speed camera. The results showed that the ratio of 7,5:1 to 10: 1 blue color of the flame and the flame propagation speed greater penembahan but with 10% CO2 20%, 30% color changing flame reddish yellow which indicates incomplete combustion occurs, and the smaller the rate of flame propagation. This is influenced by the presence of buoyancy forces generated by the combustion.Keywords: energy, gas methane (CH4), CO2, the rate of propagation of flame

Abstract

Biogas yang dihasilkan oleh aktifitas anaerobik sangat popular digunakan untuk mengolah limbah biodegradable karena bahan bakar dapat dihasilkan sambil menghancurkan bakteri pathogen dan sekaligus mengurangi volume limbah buangan. Metana dalam biogas, bila terbakar akan relatif lebih bersih daripada batu bara, dan menghasilkan energi yang lebih besar dengan emisi karbon dioksida yang lebih sedikit. Biogas yang dihasilkan oleh biodigester sebagian besar terdiri dari 54%–70% metana (CH4), 27%–45% karbondioksida (CO2), 3%-5% nitrogen (N2), 1%-0% hidrogen (H2), 0,1% karbon monoksida (CO), 0,1% oksigen (O2) dan sedikit hidrogen sulfida (H2S). Jika biogas dimurnikan dari pengotor dalam kasus ini, dari CO2, ia akan memiliki karakteristik yang sama dengan gas alam. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh CO2 dalam proses pembakaran. Dalam penelitian ini menggunakan metana sebagai bahan bakar dan ruang bakar sel Helle-Shaw dengan ukuran 50 x 20 x 1 cm. Variasi yang digunakan adalah perbandingan AFR 7.5: 1, 8.5:1, 9 :1, 9.5:1 dan 10: 1 dengan penambahan 10% 20%, 30% CO2. Hasil penelitian menunjukan bahwa Kadar CO2 berpengaruh terhadap karakteristik pembakaran CH4 dengan CO2

Abstract

In general, plastics have low density, are insulating to electricity, have varying mechanical strength, limited temperature resistance, and varying chemical resistance so that they are widely used because of their advantages. Efforts to manage plastic waste practically and effectively to reduce the widespread pollution. The purpose of this study was to find out the effect of the use of condenser cooling water on the results of the distillation of plastic waste capacity of 3 Kg. Testing was carried out in two ways: measuring the relationship of the time and heat of the kettle, the relationship of time and heat of the condenser. The results showed that the longer time achieved will be the greater the increase in the temperature of the kettle obtained that is 650C to 720C means a change (720C - 650C = 70C), and the longer time achieved will be less heat obtained ie heat value of 2805.688125 and hour later decreased by 2622.88125. In conclusion, the longer the time reached at the time of energy administration in the kettle and the provision of energy to the condenser, the greater the increase in the temperature of the kettle.
