If the gas supply valve is open fully, the flame on the gas appliance will increase in size and intensity. This can lead to a hotter flame and possible overheating of the appliance if not properly managed. It is important to always follow the manufacturer's recommendations for gas appliance operation to prevent hazards.
Adjusting the gas needle valve controls the flow rate of gas entering the burner. Decreasing the gas flow by turning the needle valve counterclockwise results in a smaller, bluer flame with less heat, while increasing the gas flow by turning the needle valve clockwise produces a larger, yellower flame with more heat.
The part on a Bunsen burner that controls the size of the flame is called the needle valve or air inlet. By adjusting this valve, you can regulate the amount of air mixed with the gas, which in turn controls the size and type of flame produced.
The adjustment valve in a Bunsen burner controls the flow of gas, allowing the user to regulate the flame size and intensity. By turning the valve, the amount of gas entering the burner can be adjusted, resulting in a smaller or larger flame.
The needle valve controls the flow of gas into the Bunsen burner, regulating the size and intensity of the flame. By adjusting the needle valve, you can increase or decrease the amount of gas entering the burner, which in turn alters the flame's temperature and size.
To put out a Bunsen burner, simply close the air vent to cut off the oxygen supply first, then turn off the gas supply using the valve on the burner. Never use water to extinguish a Bunsen burner as this can spread the flame.

When the gas control valve is turned, adjusting it will regulate the flow of gas to the burner. By opening the valve more, the flame size will increase as more gas is released. Conversely, by closing the valve, the flame size will decrease as less gas is able to reach the burner.
To shut off the water supply valve to a toilet, locate the valve usually behind or near the toilet. Turn the valve clockwise until it is fully closed. This will stop the flow of water to the toilet.
If a flame is present with the gas valve off, it indicates a potential issue with the gas control valve or a gas leak. In this situation, it is important to immediately shut off the gas supply, ventilate the area, and contact a qualified technician to inspect and repair the gas appliance.
Increase the air flow by opening the circular valve on the stem of the burner. This will cause the flame to burn more intensely and with a blue flame. When the valve is closed, the flame will burn yellow and cooler - more like a wax candle's flame.
The toilet water supply line valve controls the flow of water into the toilet tank. It can be maintained properly by checking for leaks, ensuring it is fully open or closed, and replacing it if necessary.
To shut off the cold water supply valve during a plumbing emergency, locate the valve near the fixture or appliance, turn it clockwise until it is fully closed, and check to ensure the water flow has stopped.
A Bunsen burner flame can both roar and burn quietly, by allowing more oxygen to reach the flame by opening a valve it will roar, by closing the valve the flame will flicker
The flame itself will get bigger/hotter, and the amount of 'blue' increases. Depending on the type of burner, it may or may not increase proportionately with the total flame size.
The flame may be adjusted in two ways. To just reduce the flame height reduce the gas flow. To lessen the cone, partly close the air supply valve (the sleeve at the bottom of the burner). If closed all the way the flame will become yellow and possibly smoky.
To get water back on, you can check if the main water shut-off valve is fully open. This valve is usually located near the water meter or where the main water supply enters the property. If the valve is open and you still don't have water, contact your water utility provider to ensure there are no issues with the water supply in your area.
