I wish to run my Kubota WG752 on full load @ 3500 RPM. to deliver about 13 KW. This should give me at least, 30kw of waste heat with which to Torrify biomass at an elevated temperature. The exhaust manifold of the engine is connected to a chamber containing biomass, having brought the engine up to opering temperature using natural gas. The exhaust stream has picked up considerable un oxidized "fuel" on exiting the torrifyer. My question is: can this gas stream be recycled? I have just read through the contents of a very interesting US Patent,4883570. which describes a device which is capable of converting this CO2, wood vinegar and tar laden crud into gas and liquid fuel. Is this proposal like having the tail wag the dog.? Will there be any efficiency gains by gasification without oxygen?. The introduction of steam in the process might augment the hydrogen content of the gas yeald. In which case this could be provided from the surplus water being separated from the product. There will be a considerable amount of red hot charcoal available. The bottom line is, will I have utilized 30 KW of waste energy. Check out the patent.

Wood gasification can happen in as little as 350 c BUT, happens much etter around the 800c mark.

You have to get up to the emperatures where the "destructive distillation" occurs to break down xisting chemicals into those other components that you list. You need emps high enough to disassemble and maybe recombine things like the ellulose and the famous "pyrolignous acids". I'm thinking well over 00C to even start most of those processes.

By rights, then the methane should come out first, but I never see flames shooting out of the butt ends (or the worm hole pores) until the water is one. What is going on?
