The damper is used to adjust the air volume entering the burner, which is directly related to the combustion effect of the burner. There are three methods for adjusting the damper of the methanol fuel burner (except that the damper of the hydraulic cylinder is not suitable for methanol combustion):
1. Manually adjustable damper
All methanol burners with single-stage control in Songran Methanol Combustion Equipment adopt manual adjustable damper. First loosen the fixing screw on the damper, and adjust the opening of the damper according to the amount of methanol sprayed so that the amount of combustion-supporting air and methanol sprayed match, and then tighten its fixing screws.
2. Servo motor adjustable damper
The second air door of the bipolar control burner is a servo motor adjustable air door, which uses the rotation angle of the servo motor to control the opening of the air door. Clutch button: When pressed, the cam is separated from the shaft. After the setting is completed, press it again and pop up.
Cam and Shaft Combination
1. The first stage air damper adjustment cam;
2. Two-stage fire air damper adjustment cam;
3. Two-stage fire solenoid valve action cam;
4. Fully closed, that is, the opening of the damper when the machine is shut down;
Opening setting relationship: 1>4>3>2
3. Limit-type damper adjustment
The alcohol-based fuel burner with dual-stage control has two combustion states. In the first state, the first-stage flame burns alone and requires less combustion-supporting air. In the second combustion state, the first-stage and second-stage flames burn simultaneously. , more combustion air is required. Therefore damper also because of setting two kinds of openings. This burner has two modulating dampers.
1. When the methanol burner is not started or shut down, adjust the limit screw on the damper actuator to control the air volume required for the first-stage flame (initial value);
2. After setting the first-level air intake value (when no dual-level thermostat is installed), the second-level temperature control line is connected. At this time, when the pine oil burner is started, it will first turn on a low fire and automatically open in about 10 seconds. The second stage flame (the 2# methanol pump and the 2# solenoid valve are turned on); at this time, the second stage combustion and air distribution can be adjusted. This method of methanol damper adjustment is not only economical, but also greatly prolongs the use of the methanol burner Service life (often matched with Songran high-pressure pump methanol fuel burner).
