[Gasification] Making char vs producer gas

[Peter Davies]

David, on a number of occasions you have been personally invited to view 
our systems here in Australia, including public demonstrations. When you 
finally do I hope you will stop putting out statements like this below. 
One of the biggest barriers to commercialisation we have found is the 
seemingly willful ignorance of consultants and engineers with vested 
interest in the field who point to statements like this to justify their 
positions.

As Tom Reed will also tell you gas quality can increase with deliberate 
co-production of char and in our own case is a system design choice that 
is adjustable depending on project needs. It can in no way be descibed 
as "De-tuning" the gasifier, it is rather "Optimising for co-products". 
Planned char outputs can have a number of uses including as a processed 
fuel, so are not efficiency losses in such a system.

Kind regards,
Peter
