of Oil Burning and Burners A PRACTICAL HANDBOOK COMPILED FOR THE OPERA- ON OIL AND BURNERS, THEIR CARE, BY CLAUDE C. LEVIN Price $2.00 OCEAN PUBLISHING CO. 25 WEST 42d STREET NEW YORK, N. Y. BLUE BOOK OF Oil Burning and Burners HEAT AND COMBUSTION When we speak of fuel oil we generally mean the oil which is burned in the furnaces of steam boilers. The best engineer is the one who can make the most steam with the least fuel. Heat may be produced in many ways, but for the purpose of the marine engineer it is only necessary to consider the heat generated in the furnace by burning fuel oil and coal. The degree or intensity of heat can be measured by a thermometer or pyrometer. The quantity of heat necessary to produce a certain temperature is measured in heat units. The British Thermal Unit (B.T.U.) is 1/180 of the amount of heat necessary to raise one pound of water from a temperature of 32° F to 212° F. Roughly one B.T.U. will raise the temperature of one pound of water one degree. Above 212°, water is changed into steam, by the addition of heat and the above definition is not true of steam. The best fuels contain the most B.T.U.'s per I |
