HTJX-2 Coal slagging property tester

HTJX-2 Coal slagging property tester

Product Overview:

The HTJX-2 Coal Slagging Tester is a specialized instrument developed in accordance with the national standard GB1572-89 (Method for Determination of Coal Slagging Tendency). It is designed to measure the ease with which coal forms slag during gasification or combustion processes. Widely used in coal, metallurgy, and power industry laboratories, this instrument is particularly valuable for coal-fired facilities (e.g., boilers) to pre-evaluate slagging risks and guide coal selection for optimal operational efficiency.

Working Principle:

1. Sample Preparation: Coal samples (3–6 mm granules) are loaded into the gasification chamber.
2. Ignition: Samples are ignited using charcoal of the same granularity under controlled airflow.
3. Combustion: After complete combustion, airflow is stopped, and the residue is cooled, weighed, and sieved through a 6 mm mesh.
4. Calculation: The slagging rate is determined by the weight percentage of residue >6 mm relative to the total residue.

Technical Specifications:

1. Should be matched with a blower: air volume ≥ 12m 3/h, air pressure ≥ 1000mmHg;
2. Coal sample particle size: 3 -6mm
3. The sample size is 400cm3.

Maintenance & Notes:

1.  Regular Cleaning: Clean the flue chamber, air chamber, and exhaust pipes periodically.
2. Rust Prevention: Apply anti-rust measures during prolonged storage.
3. Spare Parts: The gasification chamber is consumable and not included as a spare part.
