Regenerative Thermal Oxidizer (RTO) is a device for treating organic waste gases (VOCs), which oxidize organic matter into harmless carbon dioxide and water through high-temperature combustion. During this process, a large amount of high-temperature flue gas is generated, and if the thermal energy of these flue gases is not recycled, it will cause great energy waste. Stainless steel plate heat exchangers are key equipment for improving the overall efficiency of RTO systems for waste heat recovery.
Stainless steel plate heat exchangers utilize the heat energy of high-temperature exhaust gas to transfer heat to cold fluids (usually fresh air or process water) through heat transfer plates. High temperature exhaust gas is discharged from RTO and enters one side of the plate heat exchanger. When the exhaust gas flows through the heat exchanger, heat is transferred to the cold fluid on the other side through a stainless steel heat transfer plate. The cold fluid is heated in the heat exchanger and absorbs the heat from the exhaust gas. After being cooled, the exhaust gas is discharged, and the heat energy is recovered for preheating fresh air or other process flows.
Heat transfer plates are usually designed as corrugated or other complex structures to increase heat transfer area and efficiency. The material used is 304 or 316 stainless steel, which has excellent corrosion resistance and high strength,
The utilization of stainless steel plate heat exchangers greatly reduces energy consumption and greenhouse gas emissions. Plate heat exchangers have a compact structure, which is smaller in footprint and easier to install compared to traditional shell and tube heat exchangers.
Stainless steel plate heat exchangers are widely used in industries such as petrochemicals, coatings, pharmaceuticals, and food processing
The stainless steel plate heat exchanger plays a crucial role in the waste heat recovery system of RTO organic waste gas combustion furnace, which can effectively improve the energy utilization efficiency of the system, reduce operating costs, and meet environmental requirements. Choosing the appropriate heat exchanger structure and material based on the specific application environment and requirements can maximize its advantages and ensure the long-term stable operation of the system.

Plate heat exchanger automated assembly line
The automated production line for plate heat exchangers is an important component of the industrial refrigeration field. In the past, there were a large number of manual operations and tedious word testing work in the production process. However, with the introduction of intelligent technology, this traditional production line is showing new vitality. Automated production lines not only reduce manual labor intensity, but also greatly improve production efficiency and product quality. Through the application of intelligent control systems, the performance and stability of refrigeration equipment have been significantly improved.
Faced with increasingly fierce market competition, automated medium voltage production lines are also constantly exploring the path of intelligent development. There are many problems with manual stamping production lines, such as low production efficiency and difficulty in ensuring quality. The emergence of automated medium voltage production lines has completely changed the traditional production mode. Through the accurate positioning and high-speed stamping of intelligent robots, production efficiency has been greatly improved. At the same time, the application of automation control systems effectively ensures the dimensional accuracy and consistency of products, improving product quality and customer satisfaction.
Intelligent re evolution is the optimization and improvement of traditional automated production lines. Although traditional automated production lines can complete certain tasks, they have certain limitations for complex and changing production environments and demands. However, intelligent re evolution fundamentally improves the flexibility and adaptability of production lines by introducing technologies such as artificial intelligence and big data analysis. For example, intelligent stamping production lines can automatically adjust process parameters and mold configurations by learning and analyzing historical data, achieving rapid switching and production for different products.
The re evolution of intelligence is not achieved overnight. In practical applications, we still face a series of challenges and difficulties. Firstly, the research and development of intelligent devices and departmental monitoring require high investment, which is a significant challenge for individuals. Secondly, the application of intelligent technology involves issues such as data security and privacy protection, requiring reasonable solutions. At the same time, the reliability and stability of intelligent devices also need to be continuously improved to ensure the safety and controllability of the production process.
Calculation method for waste heat recovery from exhaust gas
There are two main approaches to calculate the potential for waste heat recovery from exhaust gas:
1. Thermodynamic Approach:
This method uses the principles of thermodynamics to determine the theoretical maximum amount of heat that can be recovered. Here's what you need to consider:
- Mass flow rate (ṁ) of the exhaust gas (kg/s) - This can be obtained from engine specifications or measured with a flow meter.
- Specific heat capacity (Cp) of the exhaust gas (kJ/kg⋅K) - This value varies with temperature and needs to be obtained from tables or thermodynamic software for the specific gas composition of your exhaust.
- Inlet temperature (T_in) of the exhaust gas (°C) - Measured with a temperature sensor.
- Outlet temperature (T_out) of the exhaust gas after heat recovery (°C) - This is the desired temperature after heat is removed for your chosen application (e.g., preheating combustion air, generating hot water).
Heat recovery potential (Q) can be calculated using the following formula:
Q = ṁ * Cp * (T_in - T_out)
2. Simplified Approach:
This method provides a rough estimate and is easier to use for initial assessments. It assumes a specific percentage of the exhaust gas energy can be recovered. This percentage can vary depending on the engine type, operating conditions, and the chosen heat exchanger efficiency.
Estimated heat recovery (Q) can be calculated with:
Q = Exhaust gas energy content * Recovery factor
Exhaust gas energy content can be estimated by:
Exhaust gas energy content = Mass flow rate * Lower heating value (LHV) of the fuel
Lower heating value (LHV) is the amount of heat released during combustion when the water vapor formed condenses (available from fuel specifications).
Recovery factor is a percentage typically ranging from 20% to 50% depending on the engine type, operating conditions, and the chosen heat exchanger efficiency.
Important Notes:
- These calculations provide theoretical or estimated values. The actual heat recovery may be lower due to factors like heat exchanger inefficiencies and piping losses.
- The chosen outlet temperature (T_out) in the thermodynamic approach needs to be realistic based on the application and limitations of the heat exchanger.
- Safety considerations are crucial when dealing with hot exhaust gases. Always consult with a qualified engineer for designing and implementing a waste heat recovery system.
Additional factors to consider:
- Condensation: If the exhaust gas temperature drops below the dew point, water vapor will condense. This can release additional latent heat but requires proper condensate management.
- Fouling: Exhaust gas can contain contaminants that can foul heat exchanger surfaces, reducing efficiency. Regular cleaning or choosing appropriate materials may be necessary.
By understanding these methods and factors, you can calculate the potential for waste heat recovery from exhaust gas and assess its feasibility for your specific application.

Rotary/Wheel Energy Recovery Heat Exchanger
There are two types of rotary energy recovery heat exchangers:full heat type and sensible heat type.As a heat storage core,the fresh air passes through a semicircle of the wheel,while the exhaust air passes through another semicircle of the wheel,and the fresh air and exhaust air pass through the wheel alternately in this way.
in winter,the wheel regenerative body absorbs heat from the exhaust(wet),when moved to fresh air side,due to reasons of the poor temperature(wet),regenerative core body would release quantity of heat(wet),when to exhaust side,and continue to absorb the heat in exhaust quantity(wet).The energy recovery is achieved by such a repeated cycle,and the working principle is shown in the figure.During the summer cooling operation,the process is reversed.
When the full heat wheel runs,water molecules in the air are absorbed into the molecular sieve coating on the surface of the honeycomb,and when they are transferred to the other side,they are released due to the pressure difference between the water molecules.
The all-heat type runner USES the fresh air to exchange sensible heat and latent heat,so as to save energy and keep good ventilation in the room.The fresh air can be pre-cooled and dehumidified in summer and preheated and humidified in winter.
