The bomb calorimeter consists of a bomb vessel, which is filled with the oxygen and contains the sample, a calorimeter vessel with the water, a stirring system, a temperature measurement system, and the ignition system, and it measures the temperature rise of the water caused by the combustion of the sample, which is used to calculate the heat of combustion; the bomb calorimeter is used for the measurement of the calorific value of the fuels, for the measurement of the energy content of the foods, for the measurement of the heat of combustion of the chemicals, for the research, for the quality control, and for many other applications, and it is available in various configurations; the bomb calorimeter is an essential instrument for the calorimetry. Bomb calorimeters are used in the fuel industry, in the food industry, in the chemistry laboratories, in the research, and for many other applications. With their combustion, bomb calorimeters are essential for the calorific value measurement.

FAQ
Q1: What testing scenarios is this calorimeter mainly applied to?
A: The bomb calorimeter is used in coal testing laboratories, fuel quality assessment, food analysis, biomass energy research, waste management, cement manufacturing and research institutions to measure the gross calorific value (heat of combustion) of solid and liquid combustible materials. It supports coal quality grading and trade, fuel oil and biofuel energy content determination, food calorie measurement, biomass fuel evaluation, refuse-derived fuel testing, and material combustion energy characterization. The oxygen bomb method provides precise measurement of total heat released during complete combustion under controlled high-pressure oxygen conditions. It is essential for coal trading, fuel quality control, food nutrition labeling, biomass energy assessment and waste-to-energy facilities where accurate calorific value determination is critical for pricing, process optimization, regulatory compliance and energy content evaluation of combustible materials across multiple industries.
Q2: What standards does the calorimeter comply with?
A: The test method follows ASTM D240 for liquid fuels, ASTM D5865 for coal, ISO 1928 for solid mineral fuels, ISO 9831 for animal feeding stuffs, and corresponding GB/T methods including GB/T 213 for coal. The instrument complies with relevant laboratory safety standards including pressure vessel safety for the oxygen bomb. Calibration should use certified benzoic acid reference standards.
Q3: What is the warranty period for the whole machine and key components?
A: The whole calorimeter is covered by a 12-month warranty. The oxygen bomb, temperature sensor, controller and ignition system are covered, while crucibles, fuses, oxygen and benzoic acid standards are consumables. Damage from improper bomb use, overpressure or unauthorized repair is excluded. Extended service contracts are available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires trained laboratory personnel familiar with calorimetric methods and oxygen bomb safety. We provide an operation manual and remote guidance. Proper sample preparation, bomb assembly, oxygen charging, ignition and result calculation are important for accurate results and safe operation. The oxygen bomb is a pressure vessel and requires careful handling.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified benzoic acid should be performed periodically, typically monthly or when results drift. Oxygen bomb pressure testing and inspection should follow the manufacturer schedule and pressure vessel safety regulations. Temperature sensor calibration every 6-12 months. Daily verification with a standard sample recommended for accredited laboratories.
Q7: Are supporting consumables universal?
A: Crucibles, ignition fuses, oxygen and benzoic acid standards are available from laboratory suppliers, though bomb-specific parts should be verified. Long-term consumable cost is low to moderate depending on testing volume.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes automation level, number of bombs, temperature measurement method and sample capacity. Additional bombs, crucibles and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the calorimeter and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged for testing laboratory setup projects. Remote guidance is provided.
Q10: What types of samples are compatible with this equipment?
A: The calorimeter measures calorific value of solid and liquid combustible materials within the sample weight and energy range. Highly volatile samples require special handling to prevent loss before combustion. Explosive or highly reactive materials require special precautions. Users should follow proper sample preparation, use certified benzoic acid for calibration, ensure proper oxygen charging pressure, inspect the oxygen bomb regularly for safety, and follow pressure vessel regulations for periodic hydrostatic testing. Proper personal protective equipment should be worn during bomb handling and ignition.
