Abstract

Partamax and partalate fuel are used as vehicle fuel in parts of the world, especially in Indonesia. Partamax and partalate have their own characteristics and if they are mixed, they will change the physicochemical properties of the pure fuel and affect the combustion behavior. In this study, an experiment was conducted on the combustion of partamax vapor, partalate and a mixture of partamax and partalate by varying the air supply by 1 liter/minute, 2 liters/minute and 3 liters/minute. The results of the combustion of fuel vapors were observed in the form of temperature by measuring using a thermocouple placed in two places with a height of 20 mm and 40 mm from the nozzle mouth and observing the flame using a camera. The results obtained from the observations are the flow of fire produced in the form of a laminar flame of all fuels, The highest flame temperature is owned by partamax fuel with an air supply of 3 liters/minute of 1047 oC on a thermocouple at an altitude of 20 mm and 1027 oC at an altitude of 40 mm, while the lowest temperature is owned by partalate fuel. This is because the octane value of partamax is higher. As the octane value increases, the flame temperature increases, but the flame height decreases. In addition, when the air supply is 3 liters/minute, a lift off phenomenon occurs in the partamax fuel and partamax-partalate mixture. This is because the octane value of partamax is higher. As the octane value increases, the flame temperature increases, but the flame height decreases. In addition, when the air supply is 3 liters/minute, a lift off phenomenon occurs in the partamax fuel and partamax-partalate mixture. This is because the octane value of partamax is higher. As the octane value increases, the flame temperature increases, but the flame height decreases. In addition, when the air supply is 3 liters/minute, a lift off phenomenon occurs in the partamax fuel and partamax-partalate mixture.

Abstract

Briquettes have been researched and developed as a substitute for solid fuels such as wood. One of them is briquettes made from processing waste such as sawdust, rice husks and even industrial waste. In this journal research, researchers are interested in knowing the characteristics of burning briquettes made from rice husk mixed with alaban wood charcoal waste which includes initial ignition, combustion rate and combustion temperature. The briquette samples used were varied in the form of rectangular and hexagonal shapes, mesh 20 and mesh 40 and the briquette printing pressure of 50 kg/cm2 and 100 kg/cm2. The results showed that the highest temperature for rectangular briquettes with a mesh of 40 and a compressive strength of 50 kg/cm2 was 412ºC and the lowest for rectangular briquettes with a mesh of 20 and a compressive strength of 100 kg/cm2. 333.33 ºC. Pressure strength affects the ignition speed, the faster the initial ignition and the longer the combustion rate due to the presence of air voids and the high moulding pressure affects the duration of the combustion process.

Abstract

Plastic waste is a significant environmental challenge, but its management is still not fully effective. Common methods such as garbage disposal, combustion, and recycling have their limitations, especially the release of harmful compounds during low-temperature plastic burning. Therefore, research continues to look for better solutions. One promising approach is pyrolysis, a process in which plastic molecules break down at high temperatures in an inert gas environment. Pyrolysis produces solid, liquid, and gas products, with liquids potentially functioning as biofuels after further repairs. The study discussed the influence of temperature and time on the pyrolysis of HDPE and PET plastics. The results showed that temperature is a critical factor, with a limited reaction temperature between 500 °C and 700 °C. Results of the pyrolyse process include tar/liquid and char/ solid residues. Strangely, 3 kg HDPE produce the highest amount of tar, about 973 ml, while 3 kg PET produce the least, about 89 ml. Overall, achieving a uniform heat distribution and optimal temperature is crucial to improving the efficiency and quality of the pirolysis product.
