1.The Secret Weapon of Water Cooling Systems
Grate water cooling works like a radiator for an engine. Hollow pipes are embedded inside the grate to form a closed loop water circuit. In high temperature zones, heat resistant alloy pipes are used, with water flow controlled at 1.5 to 2 meters per second. This quickly removes heat while avoiding vaporization. A specially designed spiral flow channel increases cooling efficiency by 40 percent, keeping the water temperature difference within 15 degrees Celsius.
2.Precise Control of Air Cooling Technology
Some grates use an intelligent air cooling system. Multiple centrifugal fans generate a directional airflow of 3 to 5 meters per second. Temperature sensors are installed at key locations. When the detected temperature exceeds 350 degrees Celsius, the air pressure is automatically increased. The air cooling grid adopts a honeycomb structure, providing 2.3 times more heat dissipation area than traditional designs. A heat resistant ceramic coating adds dual protection.
3.Synergistic Effect of Combined Cooling
Modern grates often use a water air combined cooling system. The upper part uses air cooling for rapid temperature reduction, while the lower part uses water cooling for stable temperature control. A heat exchange device is installed in the transition zone, using waste heat from exhaust gases to preheat the incoming water. The entire system achieves a heat recovery rate of up to 60 percent. The modular design allows individual cooling units to be replaced without shutting down the boiler.
