The XL-2000A energy-saving intelligent integrated muffle furnace is one of the flagship products of Hebi City Keda Instrument and Meter Co., Ltd. This advanced furnace offers significant improvements in energy efficiency, reducing both time and power consumption by up to 50% and 66%, respectively, compared to traditional models. It supports multiple specialized heating procedures such as rapid ashing, slow ashing, volatile matter determination, Roga index, and bond index. With high precision control and a user-friendly interface, it’s ideal for coal, power, chemical, metallurgy, cement, and other industries.
The furnace uses a microprocessor-based control system with touch input, ensuring accurate testing according to national standards like GB212, GB5447, and GB5449. It features PID temperature control and adaptive algorithms, providing stability and reliability. The LCD screen displays all test parameters in Chinese, making it easy to monitor progress, time, and temperature. Its integrated design ensures excellent thermal insulation, fast heating, and energy savings.
The XL-2000A is designed for a wide range of applications, including coal analysis, industrial testing, and scientific research. It supports up to 15 programmable heating stages, allowing users to customize their testing process. The furnace also includes an adjustable chimney switch for convenience, and its durable construction ensures long service life.
To use the XL-2000A, ensure the environment meets the following conditions: temperature between 0°C and 40°C, humidity below 85%, and a stable AC220V ± 22V, 50Hz power supply. Avoid placing it near strong electromagnetic fields or corrosive gases. Always place it on a stable lab bench with good ventilation.
Before starting, check the wiring and ensure all connections are secure. Only trained personnel should operate the device. Users must provide a 40A or higher circuit breaker and prepare necessary tools like ash dishes, crucibles, and volatile tins.
Key technical specifications include a temperature range of 0°C to 1000°C, ±3°C measurement accuracy, ±5°C control accuracy at 250–1000°C, and a heating time of less than 15 minutes from room temperature to 850°C. It consumes 3.5kW of power and weighs approximately 35kg.
For slow ashing tests, follow these steps: Pre-heat the ash dish to constant mass, weigh the coal sample (1±0.1g), and place it in the furnace. Start the test via the function menu, and let the system automatically guide you through the process. The furnace will heat gradually, reaching 500°C, then 815°C, and maintain that temperature for 1 hour. After cooling, weigh the residue to calculate the ash content.
If further checks are needed, repeat the burning process until the mass change between two consecutive burns is less than 0.001g. The system provides audio prompts at each stage, ensuring a smooth and accurate testing experience.
