When the air hole of a Bunsen burner is closed, the flame temperature can reach up to around 1,400°C (2,550°F). This is because the closed air hole restricts air from entering the burner, leading to incomplete combustion and a hotter, more sooty flame.
The name is a "safety flame". This is when the air hole on the Bunsen burner is closed, resulting in a flame with a yellow, sooty appearance. It is used for low-temperature heating applications.
Yes, the flame of a Bunsen burner with a closed air hole can still be used for heating, but it will produce a cooler, more yellow flame compared to a Bunsen burner with an open air hole. Adjusting the air hole allows for control of the flame temperature.
If the air hole of a Bunsen burner is closed, the flame will burn yellow with a lower temperature and produce less heat compared to when the air hole is open. The amount of heat produced would be reduced as the combustion is incomplete due to the lack of sufficient oxygen.
The "air-hole" of a bunsen burner allows some of the flame to escape so that the heating flame does not become too hot. A flame that is too hot can damage laboratory equipment. When the air hole is closed it is a yellow sooty flame like the fires we have at home.
Air hole fully open gives a 'roaring blue flame'

The hole on a Bunsen burner should be closed to create a safety flame. This flame is smaller and more controlled, reducing the risk of accidents.

yes
it's to prevent a strike-back
The flame temperature increases significantly when the air hole is closed in a Bunsen burner because the flame becomes fuel-rich, leading to incomplete combustion. This can result in a sooty, yellow flame with a lower efficiency and higher temperature, reaching up to 1300°C (2372°F) due to the excess fuel. However, this can also create safety hazards, such as the potential for carbon monoxide production.
When the air valve in closed a yellow luminous flame is observed due to carbon particles from in incomplete combustion.
It is less hot
The function that covers the air hole in a Bunsen burner is the collar.
When the hole of a Bunsen burner is half closed (or half open) the flame is mostly blue-violet in color throughout, with no orange/yellow apparent as it would be with the hole fully closed. When the hole is fully open, the flame divides into a pale voilet color outer part with a cone of intense blue color within.
