"Pumping the liquid at a point of maximum heat would be my guess as this would allow for the fastest gasification (am allowed only one message/day)"
But I thought that the PRIMARY purpose and benefit of the HTF was its ability to improve on the rate at which solids could be processed based on its ability to transfer heat to them versus melting the solids alone......not the gasification of the HTF by itself. Wouldn't that imply that the HTF should be introduced with, or at least at the same time as (if not ahead of), the solids?
(If you have a response, just piggyback it with another.)
