What Is the JRZ10 Oxygen Bomb Calorimeter?

The JRZ10 Oxygen Bomb Calorimeter (Building Material Combustion Calorific Value Determination Apparatus) is a multifunctional, highly automated test instrument controlled by advanced computer software. As a professional Oxygen Bomb Calorimeter designed for a precise GROSS HEAT OF COMBUSTION TEST, the JRZ10 features high measurement accuracy, simple operation, and high reliability, making it ideal for determining the calorific value of various combustible substances in compliance with standards like ISO 1716.

What Is the GROSS HEAT OF COMBUSTION TEST?

The GROSS HEAT OF COMBUSTION TEST is a standardized calorimetric procedure designed to measure the total heat released by a substance when it is completely burned in an oxygen-rich environment. This test is essential for evaluating the energy content and fire hazard characteristics of building products, fuels, and industrial materials in strict compliance with international standards such as ISO 1716, ASTM D5865, ASTM D240-92, and ASTM D4809-90.

Applicable Materials of GROSS HEAT OF COMBUSTION TEST

• Building Materials: Materials such as those tested under EN ISO 1716 to evaluate gross calorific potential.
• Coal and Coke: Solid mineral fuels tested in accordance with standards like ASTM D5865.
• Conventional Liquid Fuels: Petroleum products including gasoline, kerosene, fuel oil, Nos. 1-D and 2-D diesel, and gas turbine fuels (Nos. 0-GT, 1-GT, 2-GT) tested under ASTM D240-92.
• Hydrocarbon Fuels: High-energy and specialized hydrocarbon fuels evaluated in compliance with ASTM D4809-90.
• Biological and Organic Matter: Food products, dietary supplements, and agricultural crops measured for energy content.
• Waste and Refuse: Municipal and industrial waste materials assessed for refuse-derived energy potential.
• General Combustible Substances: Various combustible chemicals, wood, explosives, and industrial materials.

Main Functions and Modules

• Constant-Temperature Control System: Utilizes a reliable double-vessel structure with an outer vessel capacity of 35 L and inner vessel capacity of 2.3 L.
• Automated Water-Level Balancing: Equipped with a water-level balancing box ensuring a repeatability error of <0.5 g for precise water quantities and shorter test times.
• Efficient Stirring Mechanism: Features an imported stirring motor for rapid water circulation and thorough mixing in the inner vessel.

Important Notes of GROSS HEAT OF COMBUSTION TEST

• Ensure room-temperature variation is controlled within ≤1℃ during each measurement to maintain test accuracy.
• Properly charge the oxygen bomb containing the specimen with oxygen according to standard safety protocols before placing it into the calorimeter.
• Maintain the operating environment with relative humidity ≤85% and stable power supply (220V±10V).
