1. Requirements for the degree of automation
After selecting fuel, users should choose nozzles (burners) or fully automatic burners according to their economic capacity and equipment requirements. Generally speaking, the cost of choosing a nozzle (burning nozzle) is low, but it is difficult to guarantee safety; the cost of choosing a fully automatic burner is high, but it does not need to configure the fan and control system by itself, which is easy to operate, high in furnace temperature control accuracy, and safe. Guaranteed.
2. Select according to furnace temperature and pressure (furnace internal pressure)
When ordering a burner, you must explain to the manufacturer which type of equipment your equipment belongs to, how high the temperature in the furnace is, whether the furnace is positive or negative, and how high the pressure is. Because the furnace temperature is different, the structure of the burner is also different, and the materials selected are also different; the burner selected for the positive pressure of the furnace has a higher overcoming pressure, and the burner selected for the negative pressure of the furnace has a lower overcoming pressure.
3. Fuel type
First of all, the user must determine what fuel he uses, and choose a burner according to the fuel he chooses. For example, if the fuel is diesel, choose an oil burner; if the fuel is gas, choose a gas burner.
4. Select according to the region
Different regions have different requirements for burners. For example, in Northeast cities, the burner control system requires low temperature resistance; in Xinjiang oilfield areas, the control system is required to be resistant to high temperature and low temperature; the air pressure in plateau areas is low, and the output of standard burners is not enough here. This factor should be considered when selecting .
5. The gas burner should be selected according to the gas type and gas pressure.
Because there are many types of gas and the difference in calorific value is large, a certain gas burner can only burn this type of gas. For example, a natural gas burner cannot burn liquefied petroleum gas or coal gas; similarly, a gas burner cannot burn natural gas or liquefied petroleum gas. High calorific value gas burners burn low calorific value gas, and the output of the burner is insufficient; on the contrary, low calorific value burners burn high calorific value gas, which is prone to incomplete combustion or explosion accidents.
The burner has its own suitable gas pressure range. If the gas pressure is not within the pressure range designed by the burner, it cannot be used.
If the gas pressure exceeds the design pressure range of the burner, it is prone to danger; if the gas pressure is lower than the design pressure range of the burner, the output of the burner is insufficient.
For example, a certain area in Shanxi imports more than a dozen foreign boilers, and the attached burners are gas burners with a pressure of 15Kpa, but the gas pressure in this area is only 3-4 Kpa, and foreign burners cannot be used.
The above introduces the knowledge of burner selection. If the user needs a burner, he should explain the following points: the type of his own furnace (such as a heating furnace, boiler, etc.) the furnace temperature (the boiler does not need to be specified) the furnace pressure (positive pressure or negative pressure, pressure How much) Fuel type: If the fuel is gas, the gas type, calorific value, pressure, and whether it contains tar should be stated.
6. Select according to the special requirements for the burner, such as waterproof, explosion-proof, etc.
