Automatic Refrigeration Calorimeter for Solid Fuel Gross Calorific Value Analysis

Product Overview

This automatic refrigeration calorimeter is an advanced analytical testing instrument engineered to determine the gross calorific value (higher heating value) of combustible materials with exceptional precision. Utilizing an integrated hybrid electronic and compressor-driven active refrigeration system, this equipment maintains an exceptionally stable thermal gradient between the inner and outer vessels, completely mitigating the distorting effects of ambient room temperature fluctuations. Designed to fulfill the stringent requirements of GB/T 213 standards, it provides laboratory technicians and plant managers with dependable, uncompromised thermodynamic measurement data.

Primarily utilized across thermal power generation facilities, commercial coal mining operations, metallurgy, petrochemistry, and independent quality inspection bureaus, this calorimeter automates the thermal assessment of coal, metallurgical coke, gangue, and alternative biomass solid fuels. The fully automated operational sequence manages liquid dosing, ignition timing, data acquisition, and post-combustion discharge, minimizing procedural error and maximizing sample throughput in round-the-clock testing facilities.

Engineered for high-duty continuous operation, the system incorporates industrial-grade electromechanical components, high-integrity stainless steel construction, and intelligent monitoring algorithms. Even under strenuous testing regimes characterized by high sample volumes and wide ambient temperature sweeps, the instrument delivers reproducible, highly reliable thermochemical data that procurement and quality assurance departments can trust implicitly for contractual compliance, commercial billing, and combustion process optimization.

Detail & Parts

Key Features

• Hybrid Compressor and Electronic Refrigeration: Advanced active dual-cooling technology continuously counteracts thermal buildup, stabilizing the water temperature differential between the jacket and bucket regardless of external environmental swings to enable seamless back-to-back testing.
• Automated Gravimetric Dosing: An integrated volumetric dosing mechanism precisely controls bucket water volume with a tolerance of under ±0.1 g, eliminating operator-dependent liquid measurement discrepancies and guaranteeing consistent heat capacity values.
• Ultra-High Resolution Thermometry: The integrated sensing system achieves an exceptional temperature resolution of 0.0001 K, allowing the unit to register the most subtle combustion temperature variations and yield precise energy yield calculations.
• Optimized Double-Walled Vacuum Jacket: Built using premium corrosion-resistant stainless steel with specialized vacuum insulation, the internal bucket architecture drastically reduces radiative and convective heat loss to ensure pristine adiabatic testing conditions.
• Precision Imported Stirring Motor: A high-efficiency drive assembly guarantees uniform agitation throughout the measurement volume without introducing disruptive frictional parasitic heat, maintaining baseline equilibrium prior to sample ignition.
• Intelligent Microcomputer Automation: The automated sequence orchestrates jacket filling, bucket dosing, system venting, temperature logging, and final results calculation, requiring the technician merely to insert the loaded oxygen bomb and initiate the test cycle.
• Dual Operating Speed Profiles: Operating flexibility allows testing via a high-speed rapid mode completed in 8 minutes or less, as well as an exhaustive standard mode conforming strictly to official verification methodologies within approximately 15 minutes.
• Comprehensive Historical Data Management: On-board data handling systems support instant access to historical logs, daily sample registries, and parallel replicate comparisons, with direct export support for external PC supervisory software via standard USB connectivity.

Why Choose This Product

• Robust Thermal Equilibrium Engineering: While conventional passive calorimeters require prolonged cooldown intervals between runs or suffer drift as room temperatures rise throughout the working shift, this system's active dual-refrigeration architecture enforces absolute baseline temperature stability across multi-shift, uninterrupted testing schedules.
• Turnkey Automation and Reduced Human Error: By replacing manual liquid handling with high-precision automatic volumetric metering (within ±0.1 g) and fully managing bomb pre-conditioning, water circulation, and ignition, the instrument slashes procedural variability, enabling even newly trained technicians to achieve analytical-grade reproducibility.
• Rigorous Standard Compliance: Engineered specifically around the technical requirements of GB/T 213, this unit exhibits outstanding repeatability and reproducibility verified against certified benzoic acid reference materials, ensuring full audit readiness for certified and accredited laboratories.
• Durable Heavy-Duty Construction: Built with an all-metal framework, a corrosion-proof vacuum jacket, and premium imported mechanical components, the equipment resists the continuous mechanical wear and acidic combustion gas exposure typical of heavy fuel testing operations.
