6725 Semi-micro Calorimeter Instruction Manual In practice, the amount of heat produced by the combustion of Nitrogen in the 22 mL and 1109A bomb is negligible and is usually handled by using the Fixed HNO3 Correction for Nitrogen and setting it to 1.5. Sulfur Correction In the oxygen rich atmosphere within the bomb, sulfur in the sample is oxidized to sulfur trioxide which combines with water vapor to form sulfuric acid.
6725 Semi-micro Calorimeter Instruction Manual reasonably constant sulfur content. Any value set-up as a fixed correction will be automatically applied and the controller will not prompt the user for this value. Definitions Total acid is the amount of base required to titrate the bomb washings (milliliters). Nitric acid is that portion of the total acid in the bomb washings that result when the nitrogen in the air that is trapped in the bomb is burned at high pressure.
6725 Semi-micro Calorimeter Instruction Manual Example: Where: 16.03 is equal to the equivalent weight of sulfur in H2SO4 e1 is the nitric acid portion of the total acid correction e2 is the sulfuric acid portion of the total acid correction e1+e2 is the total bomb acid correction Sulfur Multiplier Calculation: %Sulfur × Sample mass × 10 = Sulfur (mg) Sulfur (mg) = milliequiv alents of H 2 SO 4 equivalent weight of sulfur in H 2 SO 4 10 = 0.
6725 Semi-micro Calorimeter Instruction Manual Fixed Total: The Acid Correction represents the total base required to titrate the bomb washings (in milliliters). This includes both nitric and sulfuric acid. The correction is a fixed value set by the operator. The calculation is: e1 = [((total acid)(acid multiplier)) – (% sulfur)(sample mass)(sulfur multiplier)](heat of formation of nitric acid) Using the default acid and sulfur multipliers as well as a heat of formation of nitric acid of 14.
6725 Semi-micro Calorimeter Instruction Manual Note: The values entered into the test report appear as entered in the report. Values for e1, e2 and e3 are calculated and used as energy corrections in accordance with the formulas and settings given above. The formulas used above to arrive at e1 or e2 are not the same as the formulas used for e1 and e2 which appear in most ASTM bomb calorimetric procedures. However, the sum of e1 and e2, above, is equal to the sum of the ASTM treatment of e1 and e2.
6725 Semi-micro Calorimeter Instruction Manual ASTM, ISO and Other Methods Current ASTM, ISO, and British Standard Methods differ on their treatment of the nitric and sulfuric acid thermochemical corrections. ASTM Methods call for titrating the bomb washings to determine the total acid present. This is assumed to be all nitric acid with a heat of combustion of -14.1 Kcal per mole. The amount of sulfur is then determined and converted to equivalents of sulfuric acid.
6725 Semi-micro Calorimeter Instruction Manual The values for fixed acid and sulfur, which are used in preliminary reports, will reflect a sulfur correction of 0, and a nitric acid correction of 10 calories. Conversion to Other Moisture Bases The calculations described previously give the calorific value of the sample with moisture as it existed when the sample was weighed. For example, if an air-dried coal sample was tested, the results will be in terms of heat units per weight of air-dry sample.
6725 Semi-micro Calorimeter Instruction Manual REPORTS The 6772 Calorimetric Thermometer can transmit its stored test data in either of two ways. The Auto Report Destination key on the Reporting Controls Menu toggles the report destination between the display and an optional printer connected to the RS232 printer port of the Calorimetric Thermometer.
