[TheForge] reducing fuel costs by improving forge efficiency.

[terry l. ridder]

hello;

while i have not giving up on the idea of using coal instead of propane
further research points to improving the forge and perhaps the crucible
furnances efficiency in order to reduce propane cost.

most methods to improve forge efficiency have been discussed before on
theforge in the past.

in looking at kiln designs and charcoal retort designs the most common
method is to preheat the combustion air. 

so for the near term i will experiement with pre-heating the combustion
air used by the forge.
