Waste Heat Recovery Solution
Professional Supplier of Industrial Energy-Saving Heat Exchange equipment
The Plate Gas-to-Gas Heat Exchanger is a specialized device designed for efficient heat transfer between gas streams. By stacking multi-layered corrugated plates to form interleaved channels, it facilitates thermal exchange between hot and cold gases. Combining a compact structure with high heat transfer efficiency, this equipment is widely applied in industrial waste heat recovery, exhaust gas treatment, and energy optimization
Key Features
1、Logarithmic Mean Temperature Difference (LMTD): Utilizing a counter-flow configuration, the plate heat exchanger achieves a significant temperature correction coefficient, optimizing thermal efficiency
2、Compact Footprint: Its space-saving design occupies significantly less area compared to traditional shell-and-tube heat exchlangers.
3、High Throughput Capacity: Parallel flow of hot and cold fluids along the heat exchange surfaces within the channels eliminates bypass flow, enabling broad handling capacity and extensive application in waste heat recovery.
4、Robust Quality Assurance: Advanced resistance welding technology ensures secure plate joints, complemented by manual welding for critical sections. Rigorous quality inspections with state-of-the-art testing equipment guarantee structural integrity and long-term reliability.

Key Features:
It is suitable for the recovery of waste heat in the grain industry, preheating of soybean modulation, cooling before bagging in the fertilizer industry, and heating and cooling process of powder.
Plate gas heat exchanger can be equipped with high-pres sure flushing device to facilitate the daily maintenance of equipment, to avoid blockage of the channel; plate gas heat exchanger can be customized according to customer demand for the channel width, up to 50mm wide.
The hot and humid air discharged from the material dryer first passes through the heat recovery device, and the heat in the air is transferred to the recovery device.
The heat in the air is transferred to the recovery device, and the air temperature of the lost heat energy is reduced to about 40-50 degrees and discharged to the atmosphere, and the indoor and outdoor air originally inhaled by the fresh air outlet of the material dryer is about 20-30 degrees. Air through the waste heat recovery device, absorption of heat energy, the temperature rises, and then into the oven circulation heating device, reducing the oven heating temperature difference, thus greatly reducing the oven’s electrical heating power, saving electricity.
Temperature calculation: known conditions, exhaust air temperature 85 degrees, into the wind temperature 20 degrees, heat recovery efficiency of 60%, then the temperature = (85- 20) * 60% + 20 =59 degrees. That is, after the heat recovery device, the temperature can reach 59 degrees.
