I wasn’t talking specifically about the dual fired gasifier. If a WK is sized to fuel a V-10 then if it’s only feeding a 6 cylinder it is producing more gas than it’s using. Same with any other gasifier that is not sized to a specific engine. 'Doesn’t hurt anything but it’s still a benefit to divert that excess into useful work. Making producer gas specifically to fuel a water heater or other appliance would require a continuous production of gas. Maybe a drizzler if anyone could keep one running without fairly constant monitoring. Matt R has been working on gas storage using a gasometer which could then be stored for other uses but you are still dealing with wood gas and it takes a lot more volume of gas to equal the energy of propane or methane, so a fairly large apparatus. So now I see I’m beyond the original intent of the thread so I’ll shut up.

Hello, getting rid of tar is pretty easy if you’re willing to deviate from the traditional gasifier design. I am working on a design right now that should burn wood chips quite well. I’m testing with wood pellets and getting a complete burn with no tar or moisture.

Welcome to the forum Darren. As Dave said, if you are in a sharing mood but then perhaps start your own thread on the subject, this will get you more interest and feedback on your system without the possible hurdle of sending pm’s 😊
