THE CHANGING F THE POWER SUPPLY WIT A POWER SUPPLY OF HIGHER VOLTAGE |
Replacing the power supply with the welding machine |
more hydrogene is generated |
positive |
open the valves V1 and V1 |
open the valves V1 and V1 from the GUI |
the valve v1 anv d v2 are open and enable to let the nitrogene gas pass |
positive |
WASH THE SYSTEM WITH NITROGENE |
Wash the system with Nitrogenen for few minutes BY TURNING ON THE VALVE on the nitrogene tank
|
-one can see that there is nitrogene exit from the gas outlets |
positive |
Switch on the system |
Turn off the nitrogene Turn on the systeme from the GUI
|
THE SYSTEM IS GENERATING hydrogene and oxygene |
the systeme is generating hydrogene but not oxygene |
Burn the hydrogene |
Turn on the transformator |
The Hidrogene is burning |
positive |
Switch off the system. |
Switch off the system from thGUI Switch off the transformator
|
The system goes down. |
positive |
WASH THE SYSTEM WITH NITROGENE |
Wash the system with Nitrogenen for few minutes BY TURNING ON THE VALVE on the nitrogene tank
|
All the hydrogene existing in the pipe systeme exeit |
not done yet |
Postcondition |
System off the systeme |
systeme is off |
After replacing the power supply with the welding machine, we were able to generate enough hydrogen to burn it. see the pictures below .
Fig 1 : the Hydrogene flame
Fig 2: How it looks without falme
But what we noticed is that the current going to the welding machine was only high at the beginning of the start-up (about 13 A at 230 V) and then it kept decreasing until it went down to 1,4 A at 230 V. see the pictures below :
Fig 3 : Just after starting the machine (1A is going to the transformator)
Fig 4 : After a while . One can see how much the current has decreased.
Test analysis :
The welding machine is not good enough since it cannot withstand for long time.
At the highest power of the welding machine, hydrogen was generated and burned, but even then too little.
It can be 2 Reason for the low generated quantity :
1- Either the concentration is yet too low knowing that we rise it .
2- Or the current passing through the cells is too low .
or the two reasons together .
what we have to do :
1- Test whether the membranes are ruptured.
2 - Doing a test with the maximum possible concentration of the KOH. If this is not successful we have to define which power supply should be used instead . This is done by installing measuring instruments to detecct the voltage and the current passing through the cells .
