1、 Condition of natural gas regenerative burner
A set of regenerative burner system includes at least two burners, two heat accumulators, a heat recovery system, and corresponding control devices. The baking gel and heat storage device can be directly connected together according to the actual situation on site or alternatively connected together using pipes cast with refractory materials.
2、 Working principle of natural gas regenerative burner
When one burner uses the hot air in the heat accumulator for combustion, the other burner functions as a smoke exhaust port, using a smoke exhaust fan to extract the hot air from the furnace and store heat through the burner into the heat accumulator. When the heat is fully stored, the butterfly valve acts to switch the functions of the two burners.
Whenever one burner is burning, the other is helping the heat accumulator to store heat. In heat exchange. The temperature of the skin gas in the pipeline is usually between 150-200 degrees Celsius, so both butterfly valves and smoke exhaust fans can work safely and reliably for a long time.
Proper installation and selection of regenerative burners can successfully save energy and improve combustion efficiency.
3、 Characteristics of natural gas regenerative burner:
1. Efficient waste heat recovery at high temperatures, with exhaust gas temperatures below 200 ° C, can achieve a waste heat recovery efficiency of over 80%, low fuel consumption, and significant energy-saving effects.
2. Good uniformity of furnace temperature. By using high-temperature combustion technology and alternative combustion mode, uniform furnace temperature can be obtained by changing the temperature distribution in the furnace, and the temperature difference is less than 5 ° C.
3. The structure of the waste heat recovery system is tight, achieving the compact integration of the heat storage body and the burner.
4. Increasing the furnace temperature greatly increases production capacity.
5. The environmental protection effect is obvious. Due to the implementation of high-temperature and low oxygen combustion, the concentration of nitrogen oxides in the flue gas is significantly reduced.
6. High degree of automation. Automatic reversing operation, with adjustable reversing time of 0-5 minutes.
7. The equipment has a long service life. It is 2-3 times larger than the metal preheater, with convenient installation on the furnace and low investment. Since the operation of the regenerative heating furnace, it has been running steadily and reliably. The system has a high degree of automation, flexible and simple operation, high reliability, strong anti-interference ability, easy expansion, and easy maintenance. Its process technology and automatic control level have quickly completed production in the same industry in China.
4、 Application of natural gas regenerative burner
The natural gas regenerative burner is suitable for forging heating furnaces, steel rolling heating furnaces, aluminum melting furnaces, and other high-temperature heating furnaces.
5、 Investment analysis of natural gas regenerative burner:
The operating cost and energy-saving effect of the regenerative heating furnace are 30% -60% better than ordinary heating furnaces. The one-time investment is about 30% higher than that of ordinary heating furnaces.
