Happy new year all!
Today I have finally tested out my micro controller project of which I am using to control the reaction and to keep the h-cat reaction at a set temperature, I am doing this by controlling the ambient air intake fan.
The minimum fan duty cycle is 40% any lower and the motor fails to spin, I wanted to have a minimum air flow to ensure the HHO gas is forced out and not allowed to accumulate, this reduces the risk of flash back.
With the pre-heater on and the fan at minimum duty the max exit barrel temp reaches around 170 Celsius and the second probe an inch prior to the pre-heater sitting at around 100 Celsius. As you can see in the picture above.
I was beginning to find the boundaries of my parameters and pushed up to 230 Celsius before the PWM failed and some overheating in the HHO electrolysis cell wires ended today's work.
I've had so many snags along the way, firstly with power supplies of which I have successfully solved using a rotor-verter setup, blocked torches causing pressure build up and subsequent leaks, getting enough power to the HHO cell for more gas and so on! It's certainly not for the light hearted experimenter.
A quick video showing my efforts so far is below!

Well folks I just want to say that I've finally had success with my first working iteration of a HHO & car catalytic converter to create a device for heating.
Due to it's intake of ambient air the nitrogen and oxygen will react to create NOx which is not good for your health so don't try this in an enclosed space, ensure you have plenty of ventilation and be careful working with explosive gases.

| Simple Design of HHO CAT |
In a nut shell this design is blowing in ambient air or an inert gas to dilute the HHO mixture and force it away from the inlet pipes over the catalyst generating extra heat which the heat sink prevents from traveling towards HHO gas, keeping it below ignition temperatures. The bit I'm missing is what I do with that heat. Which you can see in the rough drawing above will be to pump it through a heat exchanger.
You can find a temp chart at the following site
I recorded a quick video to demonstrate that the heat generated is beyond what the resistor is creating.
The resistor was creating around 36 deg C, the HHO got it up above 70 deg C over an inch air gap.
I also shot another video wondering what would happen if I shutdown the resistor heating. Turns out it will continue to run, however my battery was drained and began to loose gas production meaning the reaction began to cool.
