Product Overview
This system represents a cutting-edge advancement in proximate testing, integrating dual high-temperature muffle furnace modules with internal analytical balance assemblies to perform fully automated thermogravimetric analysis. By simultaneously subjecting solid samples to controlled thermal regimes, atmospheric environments, and continuous gravimetric tracking, the equipment quantifies mass loss with absolute precision. This streamlined design eliminates labor-intensive manual crucible manipulation, desiccator transfers, and cooling cycles, delivering accurate proximate determinations in a single continuous workflow.
Engineered primarily for industrial quality inspection, commercial testing laboratories, and energy production environments, this unit characterizes bulk coal, metallurgical coke, solid biomass fuels, and organic raw materials. The automated analytical protocol determines moisture, ash content, and volatile matter content, while deriving calculated fixed carbon values. By automating the entire measurement chain, the analyzer ensures seamless operational throughput for facilities running continuous shift inspections.
Built to withstand rigorous continuous operation, the equipment guarantees exceptional reproducibility and long-term mechanical reliability under demanding laboratory conditions. Centralized computerized control oversees initial tare weighing, staged thermal ramps, differential mass recordings, and automatic reporting. The resulting analytical datasets completely conform to statutory quality arbitration benchmarks, providing procurement managers and plant engineers with dependable data for financial settlement, process optimization, and regulatory compliance.
Key Features
- Dual Independent Furnace Configuration: Two thermally segregated heating chambers operate in tandem with dedicated internal balance mechanisms, enabling concurrent execution of distinct thermal phases without thermal interference or cycle delays.
- Integrated High-Precision Thermogravimetric Balance: Built-in analytical weighing hardware measures sample crucibles directly inside the active furnace environment, eliminating cooling delays, ambient moisture reabsorption, and transfer-induced weighing variations.
- High-Throughput Nineteen-Sample Batch Capacity: An automated multi-position carousel holds up to nineteen analytical samples alongside reference positions, dramatically increasing daily laboratory output compared to traditional single-sample furnaces.
- Rapid Ninety-Minute Proximate Cycle: Advanced heating chamber dynamics and synchronous weighing routines complete the full tri-parameter analytical cycle—moisture, ash, and volatile matter—in under ninety minutes per batch.
- End-to-End Autonomous Operation: The integrated computerized supervisor executes tare determination, multi-stage temperature ramps, dynamic weight recording, calculation of mass fractions, and data storage without requiring operator intervention.
- Arbitration-Grade Standard Compliance: Automated measurement routines strictly adhere to established industrial testing methods including GB/T 212 for coal analysis and GB/T 28731 for solid biofuels, producing legally valid arbitration data.
- Precision Atmosphere and Gas Delivery: Controlled gas routing introduces nitrogen, oxygen, or purified air at programmed intervals, ensuring stable inert atmospheres during devolatilization and uniform oxidizing conditions for complete ashing.
- Advanced Thermal Shielding and Balance Protection: Multi-layered ceramic fiber insulation and active cooling barriers isolate sensitive balance transducers from furnace heat radiation and convection currents, preventing measurement drift.
- Automated Data Processing and System Diagnostics: Proprietary analytical software calculates proximate percentages automatically, monitors continuous weight-loss curves, alerts operators to mechanical anomalies, and archives full test histories.
