- Page 3 1. Instrument characteristics and scope The instrument is designed and made as per the national standard “Test Methods for Calorific Value of coal”, “Test Methods for Calorific Value of Petroleum Products” and “Oxygen Bomb Calorimeter”. The heat capacity of the instrument is 14000 J/K～15000 J/K, and it is suitable to determine calorific value of combustible materials such as petroleum products without water (gasoline, jet fuels, diesel oil and fuel oils, etc.), coal, coke and paraffin, etc.

3. Instrument structure The structure of the instrument is shown as Fig.1. Figure 1 (1) Thermometer (2) Stirring motor (3) Temperature sensor (4) Handle (5) Controlling panel (6) Oxygen bomb 1. Self-sealed oxygen bomb In order to protect the oxygen bomb from acid corrosion, the oxygen bomb is made of stainless steel ICrI8Ni9Ti. - Page 5 The bucket is made of stainless steel plate. After placing the oxygen bomb into the water bucket, please add water into the water bucket to submerge the oxygen bomb. But there should be about 250～500 ml space from the water surface to the upper edge of the inner bucket. The bucket can hold 3000 g water. There is an electric stirrer in the water bucket.

are Power, Stir, Data, End, Ignite, and Reset, total six switches and a digital tube of seven digits on the panel of controller, and they are used for operation and temperature display during the whole test. The two numbers at the left indicates the temperature measurement times and the five numbers at right indicates the real temperature. - Page 7 5. Operation procedure and calculation methods 1. Preparation (1) Carefully read Operation Manual before use. (2) Carefully read GB/T 213 “Test Methods for Calorific Value of Coal” or GB/T384 “Test Methods for Calorific Value of Petroleum Products” and Calibration and Inspection Regulation of People’s Republic of China JJG 672 “Oxygen Bomb Calorimeter”...

- Page 10 A. Maintenance of oxygen bombs (1) Before each formal test, it is necessary to immerse the oxygen bomb with sufficient air (not less than 3.0MPa) in water for several minutes to observe whether the sealing performance of the oxygen bomb is good and ensure the reliability of the test results.
