I am placing this new project here in (Projects) because of the new design concept I have come up with that can be used on any wood gasifier. This design will be all metal, with may be silcone couplers to seal the pipes.
It will no longer have a check valve and two pusher blowers that can push cold air into the preheat muffler box. Instead it will rely on vaccum of the engine to move the air through the system and vaccum/pusher blower to move the air along. This pusher blower will be on the down stream side off the Preheater Muffler Box.
I am planing on using a older all metal Kirby Vaccum Cleaner if I can find one.
It will have a fabricated all metal flapper check valve insalled and a gate valve for long distance running that can isolate the Muffler Preheater from the gasifier Drop Box Preheater by closing the valve. This will prevent moisture from entering the gasifier durning very wet flooding driving conditions, like I experienced this last Argos trip across the USA. Boy I had a lot of moisture in my gasifier system, wet char bed the works. It ran well once I got it to dry out some.
The WK Gasifier Designs and workings of it will not be discussed here on this thread. Go to The 92 Dodge Dakota (from the book) thread, if you have and questions on Wayne’s Gasifier Design.
Here is a free hand drawing of what I am planing on building, to replace the old Muffler Preheater that developed a muffler leak on the trip to Argos. Your input and is welcome. Please stay on the threads topic. Thank you.
This new Muffler Preheater will have Quick release muffler couplings so maintenance and or muffler replacement can be done more easily.
I am sure I am going to fine stuff inside the old muffer preheater box once I get it removed.
I am still driving the truck and it would be a little loud with no mufflers on it. @Wayne This truck doesn’t need a second ticket.
So I will build the new (PMB) and then remove the old one and put the new one in.
The ideal I came up with is to clamp the split box or clam box around the muffler. When removing or placing the muffler there is no welding. It has couplings that holds the pipes on.
Also the muffler I am buying has a life time warranty on it , will see if this stainless steel muffler will last. (The Muffler Shop) my Friend Jerry owns has had some muffler wear outs, with this muffler and the people got new ones at no price charge for the muffler. But there was was a removal and installing charge. This will not happen with my muffler. I will remove it, if needed and replace it and put it back in place, with the couplings claps. Quick and easy. I am sure you all have had the fun of trying to get pipes a part and welding under the vehicle with muffler repair. Not fun at all.
I am waiting for the muffler to come in and then this project can get started.
Should I build the PMB out of stainless steel or metal, the old box that Wayne built is still in good shape. Heavy duty holds heat.
The only problem I think was in the mounting it directly to the frame, this might be where some of the mufflers resonating frequencies are coming from when driving in the 75 to 80 mph zone. I know it got a lot louder when the muffler develop a hole inside the Preheater Muffler Box. I like the sound of pipes but when it rattles the brain with the wrong and loud frequencies thats not good. Even the metal pipe going up to the Drop Box Preheater will have a silcone isolater between the pipes, and the pipe will not touch any part of the gasifier or truck using muffler hangers.
