I Forge Iron

I noticed the comparison between coke and propane BTU on the Phalen Horseshoeing website:

It says that one $35 bag of coke has the same BTU's as 67 Blue Rhino propane tanks. The latter is 67x17 = 1139 lbs of gas.

Does this make sense? Or is it that these amounts do about equal amounts of forging? Or, is it a typo, and it really means 6-7 tanks?

It is a little fuzzy because if you are doing small work in a big fire you are using a lot of fuel to maintain the fire.

I think their numbers are off, carbon (coke) and propane have similar heating values per unit of mass, propane has a little more.

No, it does not make sense. Two different kinds of fires involved - it's not apples to apples. Comparing pure caloric content is not valid unless you could make all the other variables disappear.

I'm a coke guy....its better than coal....better than propane.......better than natural gas...charcoal...wood, whatever...If you can get it , use it ...however it is the most expensive to buy,... but the cleanest, longest lasting fire you'll get. If you are in, or near a city, a smokeless fire is the least obtrusive to your neighbors, and most desirable ( and its more like 6-7 tanks, maybe less )
