I know this question can’t be answered w/100% accuracy without more info, but here’s the situation . I got my Blichman Floor Burner in the mail today. Brewing a 5 gallon PM batch tomorrow, but don’t have time to do a test boil like I intended (couple busy days coming up, and I don’t want my crushed grains to sit out too long). I’ll be using the 8 gallon megapot stock pot sold on this site on the burner. I was wondering if anyone with experience could give me an estimated burn off rate for a 60 min boil (and a 90 min if anyone has an answer for that) so I can determine how much pre-boil wort to shoot for. I will be doing a full volume boil btw.
