Dear Paul

The TLUD coal stove being rolled out is made by 'Silver' in Turkey. The nominal price is $400, we hear, as the imported price. It is being sold for $25 or so. 

It is a ceramic lined cast iron stove with an enamelled mild steel shell. 

It was developed for burning hard coal so it has certain issues with the lignite. It really needs a couple of modifications to do that well and the details were explained to the producers. 

There is a stove called 'Royal' which is also a TLUD with two bins that can operate continuously. It is pretty much a locally made copy of the Japanese TLUD of the same name. 

There are several 'tipped over' TLUD's, which means Cross-Draft, that as are clean and which can be refuelled for continuous burning. I can't name them all here. They are easy to make. 

A new type of TLUD is under development by 'a couple of guys' that can be refuelled easily for a long burn which may be the future 'burn type' once the benefits are shown. More later on that. 

All these stoves burn more than 95% better than the baseline. Some more than 99%. Henrick Wallman will hopefully provide some independent verification of these numbers. He has much better equipment at LNBL than anyone in UB but there may be fuel changes because of shipping. People burn frozen wet lignite so it is hard to reproduce in a remote lab. 

Stay well
