Combustion characteristics of gas fuel from basic materials arak bali

Abstract

Analyze the characteristics of gas fuel from arak Bali like shape and flame speed. Testing characteristics such as methanol and ethanol content material gas from arak Bali, after it tested the gas fuel combustion characteristics of arak Bali such as the shape and speed of flame. Testing characteristics such as the content of methane and ethanol gas from arak Bali performed in the laboratory of Forensic, while testing the ignition characteristics of the shape and speed of fuel from evaporating arak Bali done using a helle-shaw cell combustion chamber model. Air mixture ratio variations with gas fuel from arak Bali is 24/1, 25/1, 26/1, 27/1, 28/1, 29/1, 30/1 and 31/1. The observed effect is the shape and speed of the premixed flame propagation in the helle-shaw cell combustion chamber model. The results of the study, the moisture content of the basic ingredients of gas fuel from arak Bali consisting of 40% methanol and 60% ethanol. To gas fuel from arak Bali has AFR stoichiometry on 30/1. Getting closer to the AFR stoichiometry, flame color changes from reddish color faded to red, reddish blue, blue and the last is bright blue. Maximum propagation speed of fire occurred in AFR stochiometry is 328.33 cm/sec.
