According to my charts-1 ton of lignite coal=
12,ooo,ooo BTU's
3,516 kwh
71 gal.-Imp.of #2fuel or
88 gal.-Am.
and 1 hp.=.746kw
According to test results from the National Threshers Assn. Reunion at Montpelier, Ohio done June 22-24/ 1961 - their 24-75 Port Huron averaged 3lbs. of coal/hp.hr. during an economy run producing about 50 hp. So 3/2000 x 12,000,000= 18,000 BTU's /hp. Others averaged around 4lbs.of coal/hp.hr = 4/2000 x 12,000,000 =24,000 BTU's/hp.hr
According to the Nebraska Tests the very best diesel tractor does 18 hp.hr/gal and gas is about 13hp.hr/gal. At 18-- 12,000,000/88.75=13521/18= 7511 BTU's /gal.
Now If there is 3516 kwh in 88.75 gal of diesel and 1hp is .746 kw then in theory there is 53 hp/hr. in a gal of #2 diesel.
So 18/53 = 34% thermal efficiency for the diesel and for the majority of them at 16/53= 30% eff.
Now for Old Smokey- 12,000,000/53/18,000=12.5% thermal efficiency and at 4lbs of coal/hp.hr = 24000 BTU/hp.hr.= 12,000,000/53/24000= 9.4% eff.
S0 in a hundred years we have gained 20% thermal efficiency.

On the Road with Dave Gohl: Deere Departed Friend - by Dave Gohl. Have you ever had to part with a dear friend? It's not easy. If it's due to death, your feelings could be in disarray for days, months or even years. Even now after almost 4 years, I still miss my dad. I remember when I was a kid my dad sometimes would tuck my brother and I in at night and we would ask him questions about his childhood on the farm. To this day, it's some of the best stories I've ever heard. And now, I'm so glad that I asked those questions, and if I were a little smarter i
