This is a write-up I started for a new project.
I consider it a work in progress.
At this point I am looking for comments on the write-up.
Can you under stand it?
Am I getting my point across?
Propane Flame Projector Controller
Objective;
I would like to make a controller for a Propane Flame Projector to be used for entertainment.
Here is some links to an example of a commercially available Propane Flame Projector.

In order to use these safely you need a controller to monitor the flame and stop the flow of fuel if it is not igniting.
I have found many off the shelf controllers for continuous flame use like for furnaces or dryers but none for intermittent flame use. For continuous flame safety the controller will shut off the fuel if it does not see fire after a few seconds. These will not work for a flame that is only there for a short time. For intermittent flame safety the controller should shut off the fuel supply if it does not light after so many try’s.
As well as safety this controller would also provide a means of remote control so the flame can be triggered by different types of input and left on for varying amounts of time.
This Flame Projector will be used in a hunted hay ride as a startle scare. Triggered off sensors and automation controllers. Both of witch have adjustable on times.
It will also be used as part of low level fireworks shows with several spread out across hundreds of feet. These will need to be triggered by the firing system. The output of the firing system is vary short so it would need to trigger an adjustable timer. I would like multiple inputs of different durations like .5 sec, 1sec, 1.5 sec and so on.
