Episode details

Flashback Arrestor

The failed flashback arrestor had functioned successfully in Slobodan’s testing with his father for the around 10 years. Perhaps it was fate that it should fail just as we were starting our testing. Actually, you can’t just go to a welding supplies shop and get an HHO flashback arrestor, so we had to do something no-one should copy, that was to buy one designed for acetylene torches. To illustrate this point, I will read from the supplied information sheet.

Operating instructions flashback arrestor Gloorotherm

Application/mode of action

Flame arresting devices are used to protect line regulators for fuel gases and oxygen (resp. compressed air) of central gas supply systems and pressure regulators of single cylinders. In case of a wrong manipulation, they prevent an explosion back pressure into the gas supply system, and therefore greatly contribute to working safety. 

The Gloorotherm has three safety components:

  1. a gas non-return valve, which prevents a back-flow of gas against normal flow direction

  2. a flame arrester made of sintered metal, which prevents a flashback of the flame

  3. a temperature sensitive cut-off valve, which interrupts the gas supply in case of a flame return 

Safety indications 

Application in accordance with the regulations 

Flashback arrestors may only be used for the type of gas for which they are marked. The specifications regarding pressure and flow rate may not be exceeded. 

Application not in accordance with their regulations 

With improper treatment and applications not in accordance with the regulations, risks for the user and other persons may arise and damage may occur. 

In particular it is not allowed:

  • to make modifications or changes on the safety device

  • to oil or grease parts that are entering in contact with oxygen 

Putting into service 

The safety device has to be mounted gas-tight directly after the pressure regulator or line regulator. The sealings are metal sealings and require therewith no further sealing elements. The gas tightness of the connections has to be controlled. 

Putting out of service 

The safety device requires no separate putting out of service. 

Operation, maintenance and repair 


The safety devices include as a rule a gas non return valve, a flame arrester and a temperature sensitive cut-off valve. They operate automatically and independent of the operator.

Maintenance and repair

Repairs may only be performed by qualified staff and in authorised workshops. In case of improper repairs and wrong use, every responsibility for the resulting consequences will be declined. The operator has to check the safety devices after a flame return and as well periodically (according to the corresponding country specific regulations) for their safety regarding a gas back-flow and for gas tightness. If the temperature sensitive cut off valve has been activated the safety device has to be replaced 

Original instruction sheet text


Our problems did not stop with the flash back arrestor, the electrolyser had become a little leaky having been sat dormant for a good while. Slobodan managed to find enough spare parts to get it operational - however, it was increasingly leaky throughout our testing and this needs more attention moving forward. That being said, we were all set for action.

The first and most critical test for Fixing Fukushima goal, was exposing CaCO3 to HHO to see if it:

  1. exceeded the required 1000ºC to produce the cold neutrinos needed to promote inverse beta decay of Tritium (as per Dr. Alexander Parkhomov’s theory) and/or

  2. to see if there were any signs that transmutation was occurring due to the formation of coherent matter / ball lightning, in line with my understanding

so that we could have reasonable confidence that it would be beneficial to deal with the waste water at Fukushima in Japan.

I will discuss the preliminary findings in my next posting.
