Show Corn As Fuel Corn will not be used this year to any great extent as fuel for the marets will give a fair price for all that the farmers can spare There has in the past been such a diversity of opinion and so little actual knowledge regarding the profitableness of burning corn instead of coal that the University of Nebraska undertook un-dertook a comparative test to show the relative heating power of the two materials mate-rials Whether it would pay to raise corn for fuel is a question not contemplated in this Investigation but the interests of a large number of people Irving in the region re-gion of cheap corn call for the determination determina-tion of its most profitable use after it Is upon the market To make a test a good grade of yellow dent corn in the ear of this years crop and not thoroughly dry was burned under un-der the boiler used to supply power for the department of practical mechanics and the amount of water evaporated by the burning of a known quantity of corn was noted The test lasted nine and one half hours and 5232 pounds of corn and cob wore consumed The next day the same boiler was heated with screened Rock Springs nut coal for five hours burning lSSS pounds of coal and the amount of water evaporated was recorded re-corded The data thus obtained shows that one pound of coal evaporated 19 times as A much water as one pound of corn In other words 19 time as much heat was liberated In burning one pound of coal as in burning one pound of corn Several calorimeter tests were made which agreed very closely with these results re-sults The coal used cost at Lincoln 565 per ton With coal selling at tnis price and worth 19 times as much for fuel as an eciial weight of corn the fuel value of thi latter would be 350 per ton or 1225 cents rier bushel The following table shows how much coal is worth per ton when its heating power is the same as that used in the ex nprment and when corn is selling at a certain price per bushel Corn Coal Per Bu Per Ton 9 cents 5487 10 cents 541 11 cents 505 12 cents 64D 13 cents 711 li cents 757 15 cents 811 It will thus be seen that if this quality of coal were selling atless than 650 and corn were bringing 12 cents it would not pay to burn corn while corn must sell as low as 8l41 per ton to bo as cheap fuel 03 corn at 10 cents per bushel |
