High Durability Modular Design Pillow Plate High Temperature Resistance

Modular Design Pillow Plate Low Resistance High Temperature Resistance

Pillow plates have become essential across multiple industries due to their versatile applications. In the power sector, they are utilized in waste heat recovery systems for large coal-fired units, effectively addressing challenges like wear, corrosion, clogging, and leakage common in traditional tubular flue gas heat exchangers. The specially designed wide flow channel with self-cleaning capabilities ensures long-term efficient and stable heat exchange performance. Applications continue to expand into small and medium-sized coal-fired units, ORC waste heat power generation, industrial refrigerant cooling, and emerging markets including radiators and evaporators in new energy and energy storage systems.

Designed specifically for high-salt wastewater incineration flue gas characteristics (containing 3-5 times more sodium chloride/sulfate particles than conventional dust, prone to Cl⁻ stress corrosion), our modular plate heat exchanger features enhanced pillow plates with optimized flow channel design. With channel heights of 25-35mm and corrugated plates overlapping at 30°-45°, dust flow rates reach 0.8-1.2m/s (exceeding the 0.5m/s supercritical value), achieving over 60% reduction in deposition rates.

Ruiding has established the Jiangsu Province Clean Incineration Resource Engineering Technology Center and the Key Laboratory of the JICUI-Ruidings Joint Innovation Center. Our laboratory features advanced detection equipment including ICP inductively coupled plasma emission spectrometry, atomic absorption spectrophotometry, atomic fluorescence spectrophotometry, high-temperature combustion ion chromatography analyzers, high-temperature combustion rate analyzers, and rapid equilibrium flash point testers. We possess capabilities for heavy metal analysis, elemental analysis, off-gas calorific value analysis, ash melting point detection, incineration boiler water quality testing, sewage analysis, and volatile waste analysis.

Ruiding specializes in engineering, fabrication, construction, and commissioning services for industrial waste combustion treatment systems including thermal oxidizers (incinerators), heat recovery systems (boilers), pressurized vessels, flue gas treatment systems (DeSOX, DeNOx), and plate heat exchangers.
