| Summary: | Although Government policy in terms of household fuel conversion from kerosene to
fuel Liquefied Petroleum Gas (LPG) provides great savings on huge state subsidies in
the energy sector. But, this conversion process also gives a great impact in terms of
safety of users of LPG, which in general are people who do not get a good education
about safety and procedures regarding the use of LPG gas, so often reported gas leak
accident that resulted in fires. Therefore, understanding the characteristics of LPG gas
mixed with air become very important to note, in this case is the flammability limit of
mixture. By understanding the flammability limit of mixture it will be easier to avoid
the accidental fire or explosion. In this experiment, flammability limits are tested with
a test detonation of a pipe (PUD) in a circle with a diameter of 50 mm and with a total
length of 6000 mm which is divided into two parts, namely 1000 mm for the drivers
and 5000 mm for the driven. In the PUD installed four pressure sensors to determine
the pressure profile at one point and also posted four ionization probes to record the
flame front. Fuel mixture used in the driver is a stoichiometric mixture of hydrogen
mixed with oxygen at 100 kPa initial pressure driven while for the mixed-use LPG
fuel - air with initial pressure of 100 kPa. Ever greater of addition of argon diluents
mixing of fuel of LPG-air and also of LPG-oxygen hence area of flammability limit
will smaller, caused by value of ekuivalence ratio will progressively shift and and so
do activation of energi of fuel mixture also will be downhill because of release heat
reaction of the fuel to argon diluents.
