Trial for Compare the Effect on Magnetic Ring Setup around the Gas Regulator Tube

Observations

Gas consumption appears to be significantly high in the first trial performed with the magnets. This is reasonablesince the dryer is at room temperature.(This trial was taken as neglected one)

Above observation wasnt appear in the trial performed without magnets because dryer was in use before thetrial begins.

Calculation

With magnetic ring setup (Neglecting the first trial and consider the other five trials),

Without magnetic ring setup,

Thus approximately 18% of gas consumption increment has been observed.

2/2

Conclusions

No significant gas saving though the magnetic rings setting up around the gas regulator tube. Fluctuations of the gas consumption over the trial No. is reasonable because there are different No. of gas firing

times present within a cycle.

Gas consumption seems to be significantly heavy when using a dryer which gets cooled to the roomtemperature. Thermal conductivity of the metal drum is too higher than its value of the gloves. Thus Hot air flow

first transfers its heat to the drum before heating the gloves.

About 54% of gas saving can be obtain if choose a dryer to run next cycle immediately after the previous cycle

finished.

Different workers follow different methods for applying Deo liquid and inserting the towels. Some areperforming both task before the cycle starts

method1and others perform it while the cycle is running

method2

(opening the door when 8 min pass after cycle starts).Opening the door while the cycle is running yields to

escape some of the heat inside the dryer to the surrounding. Applying Deo liquid and towels before the cycle

starts yields low heating rate for the dryer than the other method, thus increases the gas firing time.

(Method 1 was utilizes by the dryer workers while performing the trial with the magnetic ring setup and the

other method was in practice while performing the trial without magnetic ring setup)

Thus the conditions present while performing the trial differs from each other though the regulator valve

position and other conditions maintained as same. This may be the cause for obtaining negative results.
