Points of reactor temperature measurements

Hello
A subject or the results are different according to the editors, although some simply do not measure, and one of good performance ..
There are 3 main places where you can measure the temperature.

- Measure the reactor body
very few do this requires a good thermocouple in a monel sheath, and this brings us little useful information

-Measure the steam coming out of the reactor close to the engine intake
This tells us if it is less than 100c that the stem may get wet, but this is not an indication that the reactor is efficient, 110 or 140 it can be as good ..
Some have results even at 90c.

-Measure the vapor or fog that enters the reactor.

This measure that many use and in my opinion is the main measure to do, we know that this temperature must be less than 100c and higher than 60c, the different value are given. (only accurate tests with a flow meter will confirm it)
As a base I operate around 75c ..
Note that several tractors with bubbler or a thermometer in the bubbler at the steam.

The control of this temperature is not easy to manage that it is bubbler, SGS, Carburator (fortunately there is a rather wide tolerance)
For the bubbler its method of heating water or exhaust and its physical dimension.
For the GV the heating area and the water level must be well calculated, and its auxiliary air intake.
For the carburettor the antechamber or the room that receives the spray is often in the exhaust must be a balance between the exhaust temperature and the heating surface.
Controlling this temperature by only increasing the water flow is not a good method.

It is true that I have not measured this temperature for a long time and it is also true that it is certainly the most important measure.
Getting to regulate this temperature is very difficult because there are many factors to manage.
Air, water, exhaust temperature.
Even the speed of the car plays a role because if it is cold it cools the engine, the exhaust, the reactor water ...
