Dear Bruce,=20
If you can get into back issues of CM you will find a superb article =
relating to the building of a heat recuperator behind a kiln.
It was a complex structure but everything was carefully planned from the =
point of the thermodynamics. The recuperation tubes were extruded as =
elbows to carry fresh air to the burners but they were heated by the =
flue gases. The burners were enclosed and monitored with UV sensors. Air =
feed was via external turbo fans. Gases emerging from the flue were so =
cool they would not ignite paper. Fuel savings were remarkable.
If I were to invest in a commercial venture, I would want this sort of =
control.
Best regards,
