Glenn Herbert wrote:And the engine analogy breaks down due to the fact that the fuel combustion is only intermittent, and designed to occur so fast that there is no time for significant radiation or conduction to cool it. The RMH configuration has the gases in contact with the core walls while burning, and turbulence needed for best combustion would bring much of the gas into contact with the walls at some point. You may get 1300+F in the heart of the riser, but much of the gas will be lower temperature, and will definitely not reach the fairly uniform 1600-1800+F that clean J-tubes are capable of to destroy the last pollution compounds.
(Ernie and Erica made statements years ago about 1100F, but more recently they are claiming well over 2000F maximum, with a caution to not exceed 2300F so that NOx pollutants are not created.)

I know that there is a temperature difference of at least 325 degrees F between my flame path in the heat riser (at least 1225F) and the hottest part of my burn tunnel (less than 900F).
