The high-temperature and high-pressure gas plate heat exchanger in the waste heat recovery system of the combustion furnace is a specially designed equipment for recovering heat energy from high-temperature exhaust gas. This type of heat exchanger needs to operate stably in a high temperature of 450 ℃ and a high pressure environment of 10000Pa, and is suitable for various industrial applications such as petrochemical, steel, and power generation industries. The following is a detailed description of its working principle, main components, advantages, and applicable scenarios.

operational principle
The gas plate heat exchanger utilizes the heat of high-temperature exhaust gas to transfer heat to the cold air through stainless steel heat transfer plates, thereby preheating the cold air and improving the energy efficiency of the system. The specific process is as follows:

High temperature exhaust gas inflow: High temperature exhaust gas enters the heat exchanger through the inlet.
Heat transfer: High temperature exhaust gas flows through a stainless steel heat transfer plate, and heat is transferred to the cold air on the other side through the plate.
Cold air heating: Cold air is heated by the heat transfer plate through the other channel of the heat exchanger.
Cooling exhaust gas discharge: The cooled exhaust gas is discharged from the heat exchanger, and the heat energy is recovered.
advantage
Efficient heat transfer: Materials with corrugated structure design and high thermal conductivity ensure efficient heat exchange.
High temperature and high pressure resistance: able to operate stably under high temperature of 450 ℃ and high pressure of 10000Pa.
Corrosion resistance: Stainless steel material provides excellent corrosion resistance and is suitable for various industrial exhaust gas components.
Energy conservation and environmental protection: effectively recover waste heat, reduce energy consumption and greenhouse gas emissions.

Stainless steel plate heat exchanger for organic waste gas combustion furnace

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.

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.

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.
