Kiln waste heat recovery and reuse system - gas stainless steel cross flow heat exchanger scheme

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.

Application of Air-to-Air Heat Recovery Exchanger in Livestock Ventilation

The Air-to-Air Heat Recovery Exchanger plays a vital role in the livestock ventilation industry by enhancing energy efficiency and maintaining optimal indoor conditions. Designed to recover waste heat from exhaust air, this exchanger transfers thermal energy from the warm, stale air expelled from livestock facilities to the incoming fresh, cooler air without mixing the two streams. In poultry houses, pig barns, and other breeding environments, where consistent temperature control and air quality are critical, it reduces heating costs in winter by pre-warming fresh air and mitigates heat stress in summer through effective thermal regulation. Typically constructed with corrosion-resistant materials like aluminum or stainless steel, it withstands the humid and ammonia-rich conditions common in livestock settings. By integrating into ventilation systems, the exchanger not only lowers energy consumption but also supports sustainable farming practices, ensuring animal welfare and operational efficiency. Its application is particularly valuable in large-scale breeding operations aiming to balance cost-effectiveness with environmental responsibility.

Plate heat recovery exchanger made in china

Heat exchangers are mainly made of materials such as aluminum foil, stainless steel foil, or polymers. When there is a temperature difference between the airflow isolated by aluminum foil and flowing in opposite directions, heat transfer occurs, achieving energy recovery. By using an air to air heat exchanger, the heat in the exhaust can be utilized to preheat the fresh air, thereby achieving the goal of energy conservation. The heat exchanger adopts a unique point surface combination sealed process, which has a long service life, high temperature conductivity, no permeation, and no secondary pollution caused by the permeation of exhaust gas.

Application of Cross Flow Heat Exchanger in Indirect Evaporative Cooling System of Data Center

The application of cross flow heat exchangers in Indirect Evaporative Cooling (IDEC) systems in data centers is mainly reflected in efficient heat exchange, reducing energy consumption, and improving data center cooling efficiency. Here are its key roles and advantages:

Basic working principle
Cross flow heat exchanger is a type of heat exchange device whose structure allows two streams of air to cross each other while maintaining physical isolation. In indirect evaporative cooling systems in data centers, it is typically used for heat exchange between cooling air and outdoor ambient air without direct mixing.
The workflow is as follows:
The primary air (data center return air) exchanges heat with the secondary air (external ambient air) through one side of the heat exchanger.
The secondary air evaporates and cools in the humidification section, reducing its own temperature, and then absorbs heat in the heat exchanger to cool the primary air.
After the primary air is cooled down, it is sent back to the data center to cool down the IT equipment.
The secondary air is ultimately discharged outdoors without entering the interior of the data center, thus avoiding the risk of pollution.
Advantages in Data Centers
(1) Efficient and energy-saving, reducing cooling demand
Reduce cooling load: By using cross flow heat exchangers, data centers can utilize external air cooling instead of relying on traditional mechanical refrigeration (such as compressors).
Improve PUE (Power Usage Effectiveness): Reduce the operating time of mechanical cooling equipment, lower energy consumption, and make PUE values closer to the ideal state (below 1.2).
(2) Completely physically isolated to avoid contamination
Cross flow heat exchangers can ensure that outdoor air does not come into direct contact with the air inside the data center, avoiding pollution, dust, or humidity affecting IT equipment. They are suitable for data centers with high air quality requirements.
(3) Suitable for various climatic conditions
In dry or warm climates, indirect evaporative cooling systems are particularly effective and can significantly reduce the cooling costs of data centers.
Even in areas with high humidity, optimizing the design of heat exchangers can improve heat exchange efficiency.
(4) Reduce water resource consumption
Compared to direct evaporative cooling (DEC), indirect evaporative cooling does not require direct spraying of water into the air of the data center, but rather indirect cooling through a heat exchanger, thus reducing water loss.
Applicable scenarios
Cross flow heat exchangers are widely used in the following types of data centers:
Hyperscale Data Center: Requires efficient and energy-saving cooling solutions to reduce operating costs.
Cloud computing data center: requires high PUE values and seeks more sustainable cooling methods.
Edge Data Center: typically located in harsh environments, requiring efficient and low maintenance cooling systems.
Challenge and Optimization Plan
Heat exchanger size and efficiency: Larger cross flow heat exchangers can improve heat exchange efficiency, but they also increase the footprint, so optimization design is needed, such as using aluminum or composite material heat exchangers to improve heat exchange efficiency.
Scaling and maintenance: Due to humidity changes, heat exchangers may experience scaling issues, requiring regular cleaning and the use of corrosion-resistant coatings to extend their lifespan.
Control system optimization: Combined with intelligent control, dynamically adjust the working mode of the heat exchanger based on external environmental temperature, humidity, and data center load conditions to improve system adaptability.
Future Development Trends
New efficient heat exchange materials, such as nano coated heat exchangers, further improve heat exchange efficiency.
Combined with AI intelligent control system, dynamically adjust the heat exchange according to the real-time load of the data center.
Combining liquid cooling technology to further improve heat dissipation efficiency in high-density server rooms.

Cross flow heat exchangers play an important role in the indirect evaporative cooling system of data centers, providing efficient heat transfer, reducing energy consumption, minimizing pollution, and improving equipment reliability. They are currently one of the important technologies in the field of data center cooling, especially suitable for large-scale, high-efficiency data centers.

Commercial Ventilation and Energy Recovery

　　Adequate indoor air quality(IAQ)involves many factors depending on the local situation and climate.Health issues like breathing problems can arise from air containing dust,pollen,or other contaminants.A poor indoor environment can also damage buildings.

　　Commercial(non-residential)air handling units tend to be larger units designed for buildings like offices,hotels,and airports.The challenge is to achieve a comfortable IAQ with as little energy input as possible.This means that pressure drop should be low(less fan power is needed)and thermal/humidity efficiency high(less energy consumed for heating/cooling/humidity control).

　　Depending on the geographical region,the primary purpose of the heat exchanger shifts between heating or cooling(and maybe also dehumidifying)the outdoor air before it enters the building.

　　The air handling unit(AHU)is at the center of a ventilation system.At a minimum,an AHU includes one or several fans in each air channel to move the air through the unit.Filters on either side remove dust,pollen,etc.,and protect the fans.Finally,a heat exchanger transfers the required heat or humidity from the exhaust air to the supply air.

　　Implementing an air-to-air heat exchanger is an excellent way to utilize what is usually considered waste heat.An air-to-air heat exchanger will use the temperature difference between the supply and exhaust air to increase the system’s efficiency.There are two types of air-to-air heat exchangers:rotary and plate heat exchangers.

　　The type and exact configuration depends on the application.Both types are made of aluminum,which has excellent properties such as efficient heat transfer capabilities and an extraordinarily long life span.We offers numerous design variables and options for each product,enabling perfect fit and performance in every AHU.

Indirect Cooling in Data Centers

Modern data centers are remarkably technologically complex, and keeping them running safely and efficiently requires continual close monitoring and management.

Maintaining the correct temperature is among the most important tasks faced by data center managers. Should the temperature and humidity rise to excessive levels inside the data center, condensation can start forming, damaging the machines within. This can cause massive damage and disruption, so it must be avoided at all costs. Fortunately, various technologies are on hand that can help keep data center temperatures at the right level.

There are numerous ways to cool a data center. Indirect air cooling uses external air, but by including an air-to-air heat exchanger, the outside air is kept in a separate loop, providing cooling without entering the server room.

Indirect cooling methods benefit by not contaminating the inside air with outdoor air pollutants and humidity. A heat exchanger keeps both airstreams separated while transferring the heat from the inside to the outside of the data center building. Consequently, the ambient and indoor air never mix.

Dry cooling is usually sufficient if the data center is located in a consistently low-temperature area, meaning no water is involved. However, by spraying water on the ambient air side of the heat exchanger, an evaporative effect is achieved, resulting in a lower indoor air temperature. This method is called indirect evaporative cooling (IEC).

Ideally suited for warm, dry climates, IEC provides excellent cooling potential with low operational- and first-cost. Ambient temperature reductions of 6-8 °C (10-15 °F) are typical in summer conditions. IEC provides up to 28% in energy savings compared to conventional free cooling and 52% to air-cooled Free Cooling alternatives.

Evaporative cooling requires a plate heat exchanger that balances high efficiency with low pressure drop, offers solid corrosion protection, and reliable water tightness. Cross-flow heat exchangers meet all these requirements while providing outstanding cooling capacity.

Our crossflow heat exchangers, especially with evaporative cooling technology, provide an efficient, low-cost, and environmentally friendly alternative to traditional cooling methods.
