Microcomputer Dual Control Fully Automatic Refrigeration Oxygen Bomb Calorimeter

Product Overview

This high-precision analytical instrument is engineered for the definitive measurement of gross and net calorific values in solid combustible materials, including raw coal, processed coke, petroleum coke, and coal gangue. Combining an active vapor-compression refrigeration unit with a dual-vessel microcomputer architecture, the system provides automated thermal regulation and high-throughput laboratory efficiency. By automating critical testing sequences—from water measurement to oxygenation and post-combustion enthalpy calculation—this equipment ensures repeatability in quality control and thermal efficiency verification.

Designed primarily for high-demand commercial laboratories, the equipment serves thermal power utilities, coal extraction and processing facilities, metallurgical plants, petrochemical refineries, and third-party inspection agencies. Fully compliant with standard test methodologies including GB/T 213-2008, the system delivers the analytical rigour required for commercial fuel transactions, combustion emission management, and regulatory compliance reporting.

Built for continuous industrial service, the calorimeter incorporates rigid structural foaming insulation to shield inner measuring vessels from fluctuating laboratory ambient conditions. Its integrated compressor continuously manages jacket temperature equilibrium, minimizing cooling correction coefficients and eliminating measurement drift. Procurement teams and laboratory managers gain an analytical asset designed for multi-shift dependability, minimal user intervention, and low maintenance overhead.

Detail & Parts

Key Features

• Integrated Compressor Refrigeration Control: An active closed-loop refrigeration unit automatically balances the temperature differential between inner and outer jackets, guaranteeing the required 1 K terminal difference and minimizing cooling correction errors.
• Microcomputer Dual-Control Architecture: A central microcomputer workstation simultaneously operates two independent calorimeter cells without operational interference, effectively doubling analytical throughput while running data-processing applications concurrently.
• Precision Automated Volumetric Water Dosing: An internal volumetric dosing mechanism meters precisely 2.3 L of water into the inner cylinder with a quantitative tolerance of ≤ ±0.1 g, eliminating manual pipetting inaccuracies and human error.
• Dual Hydrodynamic Stirring System: Featuring an internal low-drag sheet blade impeller and an external submersible electric agitator, the unit ensures uniform thermal dispersion across the entire 40 L outer jacket and the inner reaction vessel.
• Automated Oxygenation and Cotton-Thread Ignition: Routine workflows are streamlined with automated oxygen charging, pressure relief, and a reliable 24 V cotton-thread fuse ignition sequence that guarantees safe, repeatable combustion initiation.
• Complete Enthalpy Calculations: The integrated analytical software automatically determines energy equivalent heat capacity, derives bomb calorific values, and converts metrics into gross and net calorific values upon entry of moisture, hydrogen, and sulfur parameters.
• Rigid Polyurethane Foam Thermal Insulation: High-density structural foam surrounds the jacket assembly, creating an efficient barrier against room temperature swings and permitting stable operation across an ambient range of 5°C to 40°C.
• Industrial Serial Communication Interface: Standard RS-232 serial communication links the physical calorimeter units to the digital workstation, delivering low failure rates, strong noise immunity, and smooth lab integration.
• Sub-Millikelvin Temperature Resolution: Utilizing high-stability sensor circuitry, the system resolves thermal differentials down to 0.0001 K, facilitating testing accuracy of better than 0.2% verified by standard benzoic acid calibrations within a rapid 15-minute test window.
