Regenerative burners are an efficient combustion device, and their best conditions involve many aspects, including fuel type, operating temperature, system design, and operating environment. The following is a detailed analysis of these conditions:

1. Fuel adaptability

Heat storage burners can use a variety of gas fuels, such as blast furnace gas, coke oven gas, high coke mixed gas, converter gas and producer gas. Selecting the right fuel is essential to ensure combustion efficiency and reduce pollutant emissions.

2.Preheating air and flue gas treatment

Preheating of combustion air: Heat is recovered from the high-temperature flue gas using a heat storage body and used to preheat the cold air entering the system. Typically, the combustion air can be preheated to 800-1000℃.

Flue gas temperature control: Effective waste heat recovery reduces the flue gas temperature to 130-180℃, which not only enhances overall thermal efficiency but also benefits environmental protection.

3. Combustion chamber design

A good mixing effect should be ensured in the combustion chamber to promote the full combination of fuel and preheated air, so as to achieve complete combustion.

In a paired arrangement, one burner works while the other acts as a smoke discharge channel, and such alternating working mode helps maintain a uniform temperature distribution in the furnace.

4. Selection of heat storage materials

As a key component, the heat storage body is responsible for transferring heat between cold and hot media. Ideal heat storage materials should have high thermal capacity and be resistant to high temperatures. Common shapes include spherical and honeycomb designs. Honeycomb heat storage bodies, with their larger heat exchange area per unit volume, can transfer 4 to 5 times more heat than spherical ones under the same conditions. When the heat transfer capability is the same, the volume of a honeycomb heat storage body is only 1/3 to 1/4 that of a spherical one.

5. Automated control system

In order to maintain a stable operating state and maximize energy efficiency, regenerative burners need to be equipped with advanced automatic control devices to manage the switching process and other key parameters (such as temperature regulation). The switching time can be adjusted between 0 and 5 minutes according to actual needs.

6. Maintenance

Regularly checking the reliability of the ignition system is crucial, as issues with the ignition burner can lead to the main burner failing to ignite properly or going out during operation. Additionally, it is important to clean any impurities that may clog the heat storage body, ensuring the entire system remains clean and unobstructed.

To achieve optimal performance from a regenerative burner, it is essential to consider all these factors and make appropriate optimizations based on specific application scenarios. Proper installation and selection of a regenerative burner can not only save approximately 70% of energy but also increase combustion efficiency by up to 90%.
