1、 Industrial thermal management system 1. Petrochemical and Energy Sector Petroleum refining: used as a heat exchanger in atmospheric and vacuum distillation, catalytic cracking and other units to process high-temperature oil and gas (300-600 ℃), with a corrosion-resistant design that can resist sulfide corrosion. Power plant waste heat recovery: The waste heat of flue gas is recovered in the tail flue of the boiler, and the toothed structure improves the heat transfer efficiency by more than 20%, reducing the exhaust gas temperature to below 150 ℃. Chemical reaction temperature control: Control the polymerization and synthesis reaction temperature, stainless steel material is resistant to acid and alkali corrosion, ensuring continuous production safety. 2. Metallurgy and Manufacturing Industry Continuous casting cooling system: Spray cooling is applied to high-temperature steel billets, and serrated fins enhance water flow disturbance, resulting in a 30% increase in cooling efficiency compared to ordinary finned tubes. Industrial kiln waste heat utilization: Recovering furnace exhaust gas heat to preheat combustion air, with an annual energy saving rate of up to 15% -25%. 2、 Refrigeration and air conditioning system 1. Large scale refrigeration equipment Central air conditioning condense...
