Re: Best Fuel For Extended Trip

Most recent test results:
Tested anthracite (stove size) coal today with surprising results again. Travelled 6.5 miles. Subtracting out coal used to build steam initially, I was using about 4 lbs of coal per mile. See this as compared to earlier tests.
Hardwood ~ 6.0 lbs per mile
Bituminous (Pocahontas?) ~ 3.1 lbs per mile
Anthracite (Stove) ~ 4.0 lbs per mile
Today was the first time burning anthracite so perhaps, due to the perceived difficulty with anthracite, I overdid the use of the stack blower to get it and keep it lit. I don't know how much performance is lost using the stack blower. I didn't need the blower for the hardwood or bituminous. Maybe that's why the anthracite performance suffered compared to the bituminous.
BUT,,,, the anthracite was much easier to use. It keep its fire without continuous feeding for a much longer period of time than the bituminous. I could go 15 - 20 minutes on one feed before having to add more coal. This would result in a much more relaxed long distance trip than the excessive coal raking and feeding of the bituminous fire. Also, as mentioned in a previous post, I had excessive clinker and ash buildup with the bituminous which would require at least three grate and ash pit cleanings during a 6 hr steaming day on the Erie Canal.
I'll let you know how much ash and clinkers resulted from today's anthracite test when I clean out the boiler tomorrow.
NEXT TEST - is going to be nut sized anthracite rather than the stove sized used today. I'll let you know but it appears that anthracite is going to be the fuel to use for the Erie Canal trip. I still want to find some verified Pocahontas coal to test just to make sure I had the real stuff in my earlier test.
