Four Advantages of Enamel RTU Powder in GGH Applications​

1. Outstanding Corrosion Resistance, Significantly Extending Equipment Lifespan

As previously mentioned, in the harsh working environment of GGH, acidic gases are one of the main factors threatening the lifespan of heat transfer components. Enamel coatings made from enamel RTU powder exhibit exceptional corrosion resistance. Data shows that GGH heat transfer components using enamel RTU powder have a corrosion resistance performance that is 5-8 times better than that of ordinary carbon steel. In environments with sulfur dioxide, nitrogen oxides, and other acidic substances, they can operate stably for 5-10 years, far exceeding the lifespan of common metal heat transfer components. This dramatically reduces the frequency of component replacement, minimizing downtime losses and procurement costs for businesses.

2. Excellent High-Temperature Resistance, Suitable for High-Temperature Flue Gas Environments

During operation, the flue gas temperature before desulfurization in GGH is typically high, generally ranging from 120-180°C, and even higher in some situations. This requires that the heat transfer components and their surface coatings possess good high-temperature resistance. The enamel coating formed from enamel RTU powder has a high melting point, and after high-temperature sintering, the coating structure remains stable. Within the working temperature range of GGH, it will not soften, deform, or detach, thus ensuring long-term performance and allowing the heat transfer components to operate normally in high-temperature environments without compromising protection effects or heat transfer efficiency.

3. Superior Heat Transfer Performance, Ensuring System Efficiency

Heat transfer efficiency is one of the core performance indicators of GGH. The enamel coating not only provides protection but also helps to maintain or even enhance heat transfer efficiency. The components of the enamel RTU powder are scientifically proportioned, resulting in a coating with low thermal resistance that allows heat to transfer smoothly between the flue gas and the heat transfer components. Additionally, the smooth surface of the enamel coating resists dust accumulation, reducing the risk of increased thermal resistance due to dust buildup, thus maintaining stable heat transfer efficiency and ensuring the energy utilization efficiency of the entire desulfurization system, ultimately helping businesses reduce energy costs.

4. Lower Maintenance Costs, Enhancing Economic Benefits

On one hand, the long lifespan, corrosion resistance, and wear resistance of heat transfer components made from enamel RTU powder result in fewer replacements, directly lowering equipment procurement and replacement costs. On the other hand, the smooth and easy-to-clean surface of the coating simplifies and enhances cleaning during routine maintenance, reducing the workload and time for maintenance personnel and lowering labor costs. Furthermore, stable equipment operation minimizes production losses caused by breakdowns, further enhancing the economic benefits for enterprises.
