Microcomputer Automatic Ash Fusion Tester Coal Ash Melting Point Determination Apparatus

Product Overview

This microcomputer automatic ash fusion tester is an advanced laboratory analytical system engineered to determine the fusibility and melting behavior of coal ash, biomass ash, and solid fuel residues under precise thermal conditions. By automating the critical stages of heating, continuous photographic recording, and image analysis, this system eliminates operator subjectivity and delivers highly reproducible determinations of characteristic melting phases, including deformation temperature (DT), softening temperature (ST), hemispherical temperature (HT), and flow temperature (FT). The equipment combines an enclosed high-temperature heating environment with intelligent computer-driven operational logic to streamline daily routine fuel testing.

Designed primarily for quality control and research centers, the apparatus serves coal-fired thermal power plants, metallurgical coke facilities, coal chemical synthesis operations, commercial inspection bureaus, and environmental laboratories. It plays a critical role in predicting slagging, fouling, and clinkering propensities inside combustion chambers, entrained-flow gasifiers, and industrial utility boilers. By characterizing mineral phase transitions under controlled atmospheres, laboratory managers and plant engineers can make informed feedstock selection decisions and optimize combustion efficiency.

Constructed with industrial-grade mechanical and thermal components, the equipment ensures outstanding operational durability under rigorous testing schedules. The integration of high-purity silicon carbide heating elements, stable horizontal furnace geometry, and sensitive noble metal thermometry provides exceptional thermal stability and uniform temperature distribution across the sample zone. Backed by automated safety architectures and intuitive Windows-based software, this analytical platform provides long-term measurement consistency and uncompromised testing reliability in demanding laboratory environments.

• Premium Silicon Carbide Tube Heating: Equipped with a heavy-duty silicon carbide (SiC) tubular heating element, the system delivers rapid thermal transfer, superior oxidation resistance at elevated temperatures, and extended operating life under continuous daily utilization.
• Precision Platinum-Rhodium Thermocouple Sensing: A high-precision platinum-rhodium/platinum (Type S) thermocouple is positioned directly adjacent to the sample zone, ensuring rapid response dynamics and reliable temperature tracking throughout the analytical cycle.
• Strict Standards-Compliant Heating Control: The integrated closed-loop PID control algorithm executes a strict multi-stage temperature ramp conforming to GB/T 219-2004 specifications, utilizing progressive ramp rates to ensure standardized cone deformation dynamics.
• High-Resolution CCD Optical Monitoring: An industrial-grade CCD imaging assembly continuously captures sharp, high-contrast visual records of the ash cone silhouettes through a dedicated optical port, enabling real-time on-screen visualization during tests.
• Automated Ash Cone Image Recognition: The analytical software features automated identification algorithms that detect and register critical geometric transitions of the ash cone specimens, presenting live dimensional shifts directly in the display window.
• Comprehensive Data Storage and Curve Plotting: Experimental runs, high-resolution test cone imagery, corresponding temperature milestones, and dynamic temperature-versus-time heating curves are automatically archived to the system hard drive for thorough auditing and report printing.

Applications

Technical Specifications

The programmed thermal ramp profile in KT-TE21 is governed strictly by the requirements of standardized coal testing methodologies. By automatically throttling heating rates from an initial rapid phase below 880°C to an intermediate deceleration zone between 880°C and 900°C, and finally sustaining a steady 5 ± 1°C/min ramp through the critical 900°C to 1600°C zone, the system creates the exact physical environment needed to observe authentic ash cone phase transitions. The platinum-rhodium thermocouple pairs with robust power electronics to deliver steady current up to 30A without overshoot, protecting the internal silicon carbide element against thermal shock.
