In the clean energy industry, the “coal gasification process” plays a crucial role in\u00a0converting solid coal into gaseous fuel. This process involves subjecting coal to\u00a0chemical reactions with gasifying agents in specific equipment, resulting in the\u00a0production of combustible gases such as CO, hydrogen, methane, as well as non-combustible gases like carbon dioxide and nitrogen. These gases are then supplied to\u00a0various industries and used in different production processes.<\/p>\n
Case Background
\n<\/b>This case focuses on a use enterprise operating in the clean energy industry, which\u00a0supplies various gases to chemical companies in the region.Their production process\u00a0involves coal combustion in a gasifier. The combustion process generates white ash,\u00a0which needs to be collected and stored in a silo. Insufficiently burned coal forms black\u00a0ash, which undergoes combustion again.<\/p>\n
In the past, the level of white ash in the silo\u00a0was measured using a plumb bob level gauge. However, this mechanical measuring\u00a0method resulted in high maintenance costs and frequent issues of “buried plumb bob,”\u00a0impacting measurement accuracy and production.<\/p>\n
To address these challenges, RETTAR\u00a0customized a guided wave radar level meter, ensuring accurate and stable\u00a0measurement.

\nMeasurement Challenges
\n<\/b>1. The height of the silo, approximately 21.5 meters, required an instrument with high\u00a0energy intensity.
\n2. The presence of a 1-meter high upper pipe in the silo posed installation challenges\u00a0and increased the risk of interference, leading to inaccurate measurements.
\n3. The significant amount of dust generated during feeding caused interference\u00a0signals, affecting the measurement accuracy.<\/p>\n
Solution
\n<\/b>To overcome these callenges, a contact-type guided wave radar level meter was\u00a0selected for measurement. Considering the difficulty of installing rod antennas in\u00a0applications with a large measuring range, a combination of “rigid rod + flexible cable”\u00a0antenna form was customized for the customer.
\nThis design ensured that the antenna\u00a0did not touch the wall during the measurement process, eliminating the risk of “falling off\u00a0the rod” and facilitating installation.<\/p>\n

\nProduct Advantages
\n<\/b>1. The guided wave radar level meter is unaffected by material fluctuations and\u00a0effectively combats signal interference caused by dust during feeding, resulting in\u00a0more reliable signal reflection, avoiding wave loss, and ensuring accurate and\u00a0reliable measurements.
\n2. Unlike the previously used plumb bob level meter, the guided wave radar level\u00a0meter does not rely on mechanical movement for measurement. It has no moving\u00a0parts, providing high reliability and a long service life, eliminating the risk of “buried\u00a0plumb bob.”
\n3. The instrument features a dual CPU design system and equivalent sampling pulse\u00a0patent technology, offering strong hardware processing capability, high signal resolution, and sensitivity, ensuring optimal measurement performance.
\n4. The radar continuous measurement waiting algorithm for solid materials enhances\u00a0measurement reliability.<\/p>\n
