[Stoves] Design challenges for biomass fired appliances.

Otto and List: 

For others on the list, I think they need to understand that when you say: 

" Normally, a ND gasifier have no air controls, doors, ports etc " 

this refers to your own versions. Most of the TLUDS I have seen have at least primary air control - and Lanny has made some of the best. So I would modify your sentence to read: 

" Normally, a ND Peko pe gasifier ha s no air controls, doors, ports etc "

Dear Lanny, 
Normaly, a ND gasifier have no air controls, doors, ports etc. 


The only opening is at the top of the fuel chamber and the channels between the inner and outer cylinder, which are fixed. 


Just fill up the inner chamber and lit from the top and everything is just NICE. 


Have a nice weekend.

Design challenges for biomass fired appliances. 
Affordability, functionality, and durability are just a few challenges. 
Another design challenge for stoves is the various openings and how to close them. 
Openings and closures are used for, combustion air controls, doors, fuel hatches and ports, for ash removal, and for exhaust outlets. 
Openings and closures that are affordable, practical, rugged, durable and easy to use could be useful for many different stove designs. 
The stove body is the easy part. It is the openings and closures that can be a problem.
