Interasting. A chimney thermometer perhaps? I think they go up to 400c.
How does your gasifier perform at hard pulls? Did you determin yet whats the max pull you can afford?
You encouridged me to try a couple of hard experiments too and l am glad you did becouse l found some interasting things. I usualy drive home at about 70kmh, today l reved up and went for 90. For a while, the gasifier struggled, then all of a sudden a boost of power. 90 wasnt a problem (bare in mind l drive slightly uphill all the way home) and acceleration got much better. I stopped after about 10km, expecting overheated cooler, it was as warm as usual, if not a bit colder!
My thinking is, as l have the char reserve reduction, and with the usual lazy driveing, reduction being only active at the top, then gases pass to the side, fines accumulated deeper in the reduction. With a hard pull, gas got pulled down deaper, fitst constipated, then breathe well. If this is true, l discovered a new major advantige in turndown ratio being a lot higher thain l imagined so thank you for the inspiration!
