I doubt anybody here's old enough to remember.
Would 28 tons of coal be enough to heat a house during the winter?
Enough to do probably most of my neighborhood.
I have a pretty good-sized house, and most winters I can heat it for 400-500 gallons of heating oil. For those who don't use heating oil, I give you the following:
Table 1 – Average Btu Content of Fuels
Electricity:
1 KW 3,412 Btu/hr
Natural Gas:
1 Cubic Foot of Natural Gas 1,030 Btu’s
1 CCF = 100 Cu Ft = 1 Therm 103,000 Btu’s
1 MCF = 1,000 Cu Ft = 10 Therms 1,034,000 Btu’s = 1.034 MMBtu’s
Propane:
1 Gal Propane 91,600 Btu’s
1 Cu Ft Propane 2,500 Btu’s
Gasoline:
1 Gal of Gasoline (mid grade) 125,000 Btu’s
Ethanol:
1 Gal of Ethanol 76,000 Btu’s
Fuel Oil:
1 Gal of #1 Kerosene 135,000 Btu’s
1 Gal of #2 Fuel Oil 138,000 Btu’s
1 Gal of #4 Fuel Oil 145,000 Btu’s
1 Gal of #6 Fuel Oil 150,000 Btu’s
Other:
Wood (air dried) 20,000,000/cord or 8,000/pound
Pellets (for pellet stoves; premium) 16,500,000/ton
Coal 28,000,000/ton
These standards of measurement make comparisons of fuel types possible. For
example:
· The heat content of one gallon of fuel oil roughly equals that of 41 kWh of electricity,
137 cubic feet of natural gas, 1.5 gallons of propane, 17.5 pounds of air-dried wood,
17 pounds of pellets, a gallon of kerosene, or 10 pounds of coal.
· One million Btu’s is the heat equivalent of approximately 7 gallons of No. 2 heating oil or
kerosene, 293 kWh of electricity, 976 cubic feet of natural gas, 11 gallons of propane,
125 pounds of air-dried wood, 121 pounds of pellets, or 71 pounds of coal.
