Natural Gas Burner

Ndenye Details

There are two kinds of natural gas burner by combustion method: Blast air burner and non-blast air burner. The internal-mixed multiheads and external-mixed multiheads are applied in the burner with safe combustion, stabilization and efficiency.  Wide range of power adjusting. The different type of automatic control system can be applied according to the flame size required from the customers.

Blast air burner
The blast air burners can be divided into the electromechanical integration type and split type according to different structures of the burner. The series of burners are composed of multiple internal-mixed inside nozzle,external-mixed nozzle and air distribution duct.  In order to realize complete combustion and facilitate adjustment, the air shall be divided into two parts to enter into the burner during combustion(the primary air and secondary air). The flame shape and combustion conditions shall be adjusted by adjusting the primary air and secondary air flow and air speed, to realize stable and complete combustion. It can be applicable for the high-pressure,medium-pressure and low-pressure fuel gas and the product has been obtained the National Patent with the patent number ZL00200606.5.











1. The burners are compact structure,artistic appearance and convenient installation.
2. The method of combining the internal-mixed multipleheads and external-mixed multiheads are applied, to realize safe,stable and high-efficient combustion.
3. The designed pressure of the natural gas is 8-10KPa usually and it can also be designed according to the actual working conditions of the user.
4. Wide power adjustment range:30% to 110%.
5. The flame dimensions can be designed according to user’s requirements.

8. The system shall be equiped with flame detection, over-temperature, overpressure, leakage detection in valve groups and other safety interlock protection.
9. If the self-control system is removed, normal combustion can be conducted with manual operation, which is easy to adjust.

Ọkụ anaghị agba ọkụ
The non-blast burners can be divided into the non-blast burner and non-blast / blast burner according to different forms of the air distribution. The burners adopts the new design idea, which combine the traditional combustion process( the single internal mixed and the external mixed combustion), forming a new type of internal and external mixed combined non-blast fuel gas burner. The non-blast / blast burner is also the new burner which combine the non-blast combustion technology and blast combustion technology. The s burners have been obtained the National Utility Model Patent with the patent number ZL94248195.X.
Till now, more than 500 sets of non-blast burners have been applied in the Jidong, Daqing, Liaohe, Dagang, Shengli, Zhongyuan, Henan, Changsheng oilfield, which stable performance, convenient operation, creating the high economic and security benefits.

Performance e ji mara
1. The non-blast combustion technology is applied in the large negative pressure fuel gas furnace, heating furnace and industrial furnace. The single burner can be non-blast high-efficient combustion in the fuel gas negative pressure furnace with less than 20t/h (14MW or 1200*104kcal/h).
2. It can be realized that the stable and high-efficient combustion within the designed scope of 30% to 110% output, meeting requirements for the ulimate load.
3.  Local control. It can be electricity-free self-control. With simple operation, it is applicable for outdoor operation.
4. The non-blast / blast burner can be operation with or without blast. It is wide scope of application.
5. The blast air is forced to work before the igniton in the non-blast / blast burner, to guarantee safe ignition. After the ignition is Ok and the main fire is established, the fan is stopped automatically. The air and the gas can be automatic matched by utilizing the fuel gas pressure and the negative pressure of the furnace chamber. So that the safe and high-efficient combustion is guaranteed and the ulimate energy-saving effect is reached.
6. According to the user's requirements, the fire-off protection, automatic ignition control, automatic adjustment and the interlock control system required for operation can be configured with stable performance.
7. In addition to the natural gas, the burners shall also be applicable for the semi-water gas, coke oven gas, gas and so on. The designed pressure shall be 20-50kpa.
