The kiln waste heat recovery and reuse system aims to fully utilize the high-temperature heat in the kiln exhaust gas, and achieve a win-win situation of energy conservation and environmental protection through gas stainless steel cross flow heat exchangers. The core of this solution lies in the use of a stainless steel cross flow heat exchanger, which efficiently exchanges heat between high-temperature exhaust gas and cold air, generating hot air that can be reused.

Working principle: The exhaust gas and cold air flow in a cross flow manner inside the heat exchanger and transfer heat through the stainless steel plate wall. After releasing heat from exhaust gas, it is discharged. Cold air absorbs the heat and heats up into hot air, which is suitable for scenarios such as assisting combustion, preheating materials, or heating.

Advantages:

Efficient heat transfer: The cross flow design ensures a heat transfer efficiency of 60% -80%.
Strong durability: Stainless steel material is resistant to high temperatures and corrosion, and can adapt to complex exhaust environments.
Flexible application: Hot air can be directly fed back to the kiln or used for other processes, with significant energy savings.
System process: Kiln exhaust gas → Pre treatment (such as dust removal) → Stainless steel heat exchanger → Hot air output → Secondary utilization.

This solution is simple and reliable, with a short investment return cycle, making it an ideal choice for kiln waste heat recovery, helping enterprises reduce energy consumption and improve efficiency.

During the drying process of alumina powder, a large amount of high-temperature exhaust gas is generated. If it is directly discharged, it not only wastes heat energy but also increases environmental load. The waste heat recovery and reuse system for drying aluminum oxide powder effectively recovers heat from exhaust gas through a gas stainless steel cross flow heat exchanger, achieving energy-saving and environmental protection goals.

Working principle: The system utilizes a stainless steel cross flow heat exchanger to exchange heat between the high-temperature exhaust gas emitted during the drying process and cold air. The exhaust gas and cold air cross flow in the heat exchanger, and the heat is transferred through the stainless steel plate wall. The cold air is heated into hot air, while the exhaust gas is cooled and discharged.

Program features:

Efficient recycling: The cross flow design has a high heat exchange efficiency, reaching 60% -80%, fully utilizing the waste heat of exhaust gas.
Durable: Made of stainless steel material, it is resistant to high temperatures and corrosion, and suitable for the characteristics of aluminum oxide powder drying exhaust gas.
Widely used: Recycled hot air can be used for preheating raw materials, drying assistance, or heating, reducing energy consumption.
Process description: Drying exhaust gas → Dust removal pretreatment (if necessary) → Stainless steel cross flow heat exchanger → Hot air output → Reuse.

This solution has a compact structure and stable operation, making it a practical choice for recovering waste heat from drying aluminum oxide powder, helping enterprises save energy, reduce emissions, and improve efficiency.
