1. Requirements for the degree of automation
After selecting the fuel, users should choose nozzles (burners) or fully automatic burners according to their economic capabilities and equipment requirements.
. Generally speaking, the cost of choosing nozzles (burners) is lower, but safety issues are difficult to guarantee; the cost of choosing fully automatic burners is higher, but there is no need to configure the fan and control system by yourself, it is easy to operate, the furnace temperature control is high, and safety is guaranteed.
2. Selection according to furnace temperature and pressure (furnace internal pressure)
When ordering a burner, be sure to explain to the manufacturer what type of equipment your equipment belongs to, how high the furnace temperature is, whether the furnace is positive pressure or negative pressure, and how high the pressure is. Because the furnace temperature is different, the structure of the burner is different, and the materials used are also different; the burner selected for positive furnace pressure overcomes higher pressure, and the burner selected for negative furnace pressure overcomes lower pressure.
3. Fuel type
First, the user must determine what fuel he uses and select a burner according to the fuel he chooses. For example, if the fuel is wood, choose an oil burner; if the fuel is gas, choose a gas burner.
4. Choose according to the region
Different regions have different requirements for burners. For example, in cities in the northeast, the burner control system requires low temperature resistance; in the Xinjiang oil field area, the control system is required to be both high temperature and low temperature resistant; the air pressure in the plateau area is low, and the standard burner is not strong enough here, so this factor should be considered when choosing.
5. The gas burner should be selected according to the type of gas and gas pressure.
Due to the large variety of gas types and large differences in calorific value, a certain gas burner can only burn that type of gas, such as a natural gas burner cannot burn liquefied gas or coal gas; similarly, a coal gas burner cannot burn natural gas or liquefied gas. A high calorific value gas burner burns low calorific value gas, and the burner output is insufficient; conversely, a low calorific value burner burns high calorific value gas and is prone to incomplete combustion or explosion accidents.
Burners have their own gas pressure ranges. If the gas pressure is not within the pressure range designed for the burner, it cannot be used.
If the gas pressure exceeds the burner design pressure range, it is easy to cause danger; if the gas pressure is lower than the burner design pressure range, the burner output is insufficient.
For example, a certain area in Shanxi imported more than a dozen foreign boilers, and the attached burners were gas burners with a pressure of 15Kpa, while the gas pressure in the area was only 3-4 Kpa, so foreign burners could not 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 furnace (such as heating furnace, boiler, etc.) furnace temperature (boiler does not need to be explained) furnace pressure (positive pressure or negative pressure, how much pressure) fuel type: if the fuel is gas, it is necessary to explain the gas type, calorific value, pressure, and whether it contains tar.
6. Select according to special requirements for the burner, such as waterproof and explosion-proof.
