The automatic combustion control, or ACC, of boilers designed for shipping, is a unit that contains a programmable sequence control to operate the pilot burner, furnace purge, and the burner piston valve. It also transmits the automatic adjustment commands for the correct combustion of air quantity and fuel oil quantity.
The air vents in a Bunsen burner control the amount of air entering the burner. By adjusting the air vents, you can control the flame produced by the burner, allowing you to achieve different types of flames for specific experiments or applications.
The stopcock on a Bunsen burner is used to control the airflow into the burner. By adjusting the stopcock, you can regulate the amount of oxygen that reaches the flame, which allows you to control the flame size and temperature.
The nozzle that the burner tubing connects to allows gas to enter into the burner. Also, the nozzle has a lever that allows you to control how much gas will flow into the burner.
Depends on the age of the heater. If you light the pilot with a match, you should be able to remove the thermocouple with the burner in place. The end that is in the flame will pull out of the clip that holds it. The control valve end unscrews. If you have a newer one that lights the pilot with a sparker, you have to remove the burner as a unit. There should be two screws holding the cover plate in place, the gas line to the burner, the thermocouple and the wire for the sparker. Disconnect all of these from the control valve and the unit slides out through the hole. Then change the thermocouple and replace.
just it control the quantity of air supplied to burner .It is also called as damper.
Control of the ratio gas fuel/air in the burner.
The device used to control air flow in a Bunsen burner is called a "air hole" or an "air vent." It is typically located at the base of the burner and can be adjusted to regulate the amount of air entering the burner, affecting the flame's intensity and color.
Advantage of modulating burner control, versus on-off control, is it provides more uniform heat output. The modulation range depends on burner design, e.g., 25%-100%. In such cases, the burner will modulate between 25%-100% and operate on-off between 0% and 25%. The modulation signal is obtained from a process parameter to be controlled, e.g. steam pressure.

No, the Bunsen burner is adjusted by turning the gas valve to control the flow of gas and adjusting the air intake holes on the burner tube to control the air/gas mixture. The collar is typically used to adjust the size and shape of the flame.
The barrel of a Bunsen burner controls the amount of air mixing with the gas, affecting the flame's color and intensity. By adjusting the barrel, you can create a hotter, blue flame or a cooler, yellow flame for different heating needs.
