The burner is divided into three types according to the operation mode: single-stage fire burner, two (double) stage fire burner, and proportional adjustment burner.
1. Single stage burner
The single-stage fire burner is as big as it is ignited, and the firepower and flame size will not change, and there are only two states: start and stop. Single-stage fire burners are used in heating industries that do not require high temperature or pressure control and allow relatively large errors in temperature or pressure. Generally, burners with a power below 600KW (500,000 calories) are mostly single-stage fire burners.
2.Two, double stage fire burner
The working mode of the double-stage burner is small fire-high fire, first light the small fire, and then light the high fire after the small fire is stable. That is to say, the burner has two working points, which can work on one stage of fire (low fire) or two stages of fire (high fire). There are three states of high fire, low fire and stop. Double-stage fire is used in the heating industry that requires high temperature or pressure control and allows a temperature error of 10°-20°. Burners with a power greater than 600KW (500,000 calories) are mostly double-stage fire burners.
3. Proportion adjustment burner
The proportional adjustment burner also starts with a small fire, and then operates according to the required ratio. This kind of burner has unlimited working points, and the firepower and flame size can be switched at any point within the power range, which is equivalent to countless gears. The proportional regulating burner controls the temperature and pressure extremely accurately, almost in a stable state. For example, if the temperature is set to 100°, then the proportional regulating burner will always adjust the firepower of the burner within the range of plus or minus 1° (99° or 101°) at 100°.
The proportional adjustment burner is divided into two types: mechanical proportional adjustment and electronic proportional adjustment. The mechanical proportional adjustment burner controls the fuel and air flow through a servo motor to drive the mechanical linkage; the electronic proportional adjustment burner has two servo motors, and the independent servo motors control the flow of fuel and air.
Now the low-nitrogen 30 mg burners required by the country are all electronic proportional adjustment burners.
