Hello all,
Despite perusing the web, that a concise, general burner parameters--e.g. number of burners, orifice diameter, gas PSI, etc.--to chamber dimensions formula/ ratio for gas forges is absent bewilders me. Although finding orifice diameter to PSI to energy output (typically in BTUs) charts is easy, you would figure such a rule would be paramount and ubiquitous given metalsmiths' penchant for adapting and customizing their equipment. And the dimensional modularity of a firebrick gas forge (this problem is contingent and exigent for my plans to construct one) not only embodies those characteristics, but moreover greatly depends on this formula/ ratio with each rearrangement of the bricks. Plus, coal is becoming expensive and scarce while natural gas prices plummet.
Thanks for your time and help,
Steven
