Regenerative burners are highly efficient combustion devices, and their optimal operating conditions involve multiple aspects, including fuel type, operating temperature, system design, and maintenance management. The following are the optimal operating conditions summarized based on search results:

1.Fuel Type Applicable fuel:

Regenerative burners can use a variety of fuel gases, such as high-aluminum gas, coke oven gas, high-coke mixed gas, converter gas and producer gas, etc.

Fuel characteristics: The selected fuel should have good combustion performance and not contain too many impurities to reduce the corrosion or blockage of equipment.

2.Preheating air/gas temperature High temperature preheating:

The combustion air or gas is preheated by recovering the waste heat of flue gas through heat storage body, and the temperature of combustion air can be raised to more than 800-1000℃.

Efficiency guarantee: This high temperature preheating can improve the combustion efficiency and achieve a thermal efficiency of more than 70%.

3.Flue Gas Temperature Control Low Emission:

Under normal operating conditions, the flue gas temperature should be maintained at a low level (approximately 130-180℃), indicating effective utilization of waste heat.

Overheating Prevention: The upper limit of flue gas temperature at the regenerative bed outlet is generally set to no more than 250℃, ensuring economic efficiency and protecting subsequent equipment from damage.

4.Flame state and distribution Uniform heating:

The alternating combustion can form a uniform temperature distribution in the furnace, with a temperature difference of less than 5℃.

Flame characteristics: An ideal flame should be rigid, of moderate length and have a uniform temperature distribution along the length direction.

5.System Configuration Requirements Paired Installation:

Thermal storage burners are typically installed in pairs, with one unit operating while the other serves as a flue gas discharge channel for continuous operation.

Directional Switching Mechanism: Equipped with automatic directional switching valves and control systems, it supports adjustable switching intervals ranging from 0 to 5 minutes, ensuring smooth combustion process transitions.

Compact Structure: The integrated design tightly combines the thermal storage unit with the burner, facilitating on-site installation and maintenance.

6.Environmental and Safety

Considerations Low NOx Emissions: The implementation of high-temperature, low-oxygen combustion significantly reduces nitrogen oxide concentrations, contributing to environmental protection.

Safety Measures: Strict isolation between air and gas pipelines must be enforced throughout the system to prevent direct contact that could trigger explosion risks. Regular inspections of ignition nozzles should also be conducted to ensure reliable combustion performance.

7.Maintenance Points Cleaning and maintenance:

Pay attention to cleaning the dust or other impurities that may accumulate in the heat storage body to prevent affecting the heat transfer effect.

Component replacement: For vulnerable parts such as ignition electrode, fire detection device and burned nozzle brick damaged by erosion, timely replacement should be made.

In conclusion, to fully leverage the advantages of regenerative burners, users need to comprehensively consider all the aforementioned factors and adjust parameter settings and daily management strategies according to specific application scenarios. Proper installation and selection of regenerative burners can not only significantly reduce energy consumption but also enhance overall production efficiency and product quality.
