Variation Of Air Speed On Energy-Saving Stoves With Waste Coconut Oil Frying Getas

Abstract

Waste coconut oil (WCO) from brittle draining can be used as fuel for multifuel stoves and can be used to boil water. Combustion air velocity is one of the factors that affect the combustion process. Air velocity in a multi-fuel stove with WCO fuel greatly affects the character of the fire produced. The research was conducted with the aim of obtaining the character of the fire and the temperature of the water boiling process at variations in air speed and the length of the WCO combustion flame. This research process was carried out with a multifeul stove by measuring the temperature and boiling time of 0.5 liters of water using variations in air velocity of 10 m / s, 12 m / s and 14 m / s by using 20 ml of WCO for each test. The results at a speed of 14 m / s tejadi the highest flame this occurs high air flow velocity causes a faster temperature rise. The greater the air supplied will accelerate the oxidation process, so that the fuel decomposition process will be faster.
