Greetings Everyone—Here is this week’s update:
Thanks Kyle for posting videos of today’s visit. They are a great addition. If you come again and the full startup works like it is supposed to, you can do a video of that as well. As you now know, I gave him the grand tour including a ride in my Toyota CharCar. He left with renewed motivation and “ideas” for his anticipated wood gas project. I could see the wheels turning. Fortunately, Kyle’s videos don’t include the embarrassing moments. I learned a lesson today—don’t try to drive on gasoline with the air valve closed and a plug in the gasifier air intake. I haven’t noticed any permanent damage, but my convex drum lid was sucked into a concave shape. I stepped on it to pop it back out. Put it on, finished starting up the gasifier, and away we went. Apparently my gasifier is very tight.
If any of you ever come near Oxford, NC, exit 206 on I-85, consider stopping by and I’ll give you a ride, too.
I made several slight alterations in the gasifier last week, but no test drive due to a week of rain. I added a larger container which is made of plastic for water and a cut off valve for the drip mechanism. Also located the drip “glass” so I can see it through the rear-view mirror. Made slight mechanical improvements to the reactor lid lock down mechanism. Replaced the A/C size pool filter with the larger B size and made a sack filter out of a bath towel to go over it which ties only at the top. I replaced the flimsy AutoZone control cable on the gasoline valve with a much sturdier one from NAPA. I have plans to add a large grill thermometer to the final filter container, positioned so I can also see it through the rear-view mirror.
Thanks Bruce for the threaded rod idea for your charcoal grinder. I hope to start on it before the end of the week. Thanks Gary for the advice about adding water and exhaust gas. I think it ran cooler today. I will add both from now on. Thanks for the encouragement Koen. Eddy, thanks for including my project in your drawings and thanks for the much-anticipated drawings of Leitinger’s Mercedes.
Finally, I have some questions for you folks: Can anyone recommend an internet source and specific wool material product for making sack filters?
Kristijan, with your style nozzle, how do you monitor the reaction temperature? How do you know when and what adjustments to make to the water drip and exhaust gas? I would like to try your style nozzle, but without a viewing port or temperature guage in my reactor, I am wondering how I can control the reaction.
Bruce, is there a cone shaped collector or some collection container inside your MGB cyclone?
Koen, please help out someone who doesn’t like to work formulas and suggest a reasonable diameter for a single-nozzle and also a four-nozzle arrangement for my charcoal gasifier (my engine is 1.6 liters.) I know I will need to make some change soon, so I’m trying to decide what to try next. You may have provided the nozzle specs for a similar sized engine somewhere already. Just point me in that direction, if you have. Thanks.
