Because the yellow flame produces less heat energy than the blue flame, and if you use the yellow flame, more chemical energy in the gas will be transferred into light energy than heat energy, which would be a waste of energy.(Cause your goal is the heat up the beaker.)
The metal mesh is called a wire gauze or a wire mesh. It is placed on top of the tripod to evenly distribute the heat from the Bunsen burner and prevent direct contact between the glassware and the flame, reducing the risk of thermal shock and cracking.
If you need to heat something: use an electric hot plate, water bath, or incubator. If you need a naked flame: light a match, lighter, or candle. If you need to work glassware: a butane lighter with a concentrated flame may work for small glassware (e.g. pipettes), for larger pieces you may need to go to a glassworking shop or find a Bunsen burner or forge.
the iron ring, the wire mesh over the ring, the beaker or whatever else was being heated. There are special tongs for most types of glassware or porcelain objects that are heated over a Bunsen burner.

It should be placed on a Safety Heat Proof Mat on to a gauze and then on to a tripod.
A wire gauze is typically used to support glassware above a Bunsen burner. It helps to distribute the heat evenly and prevent direct contact between the glassware and the flame, reducing the risk of breakage.
A wire gauze with a ceramic center is commonly used to support glassware above a Bunsen burner. This helps distribute the heat evenly and prevent direct contact between the glassware and the flame. The wire gauze is placed on a tripod stand to hold the glassware securely in place during heating.

The mat is called a wire gauze or a ceramic center. It helps to distribute the heat evenly and protect the glassware placed on top of the Bunsen burner from direct heat.
A retort stand with a clamp or a tripod with a wire gauze would typically be used to suspend glassware over a Bunsen burner. This equipment provides stability and allows for precise control of the height and distance of the glassware from the flame. It is important to use heat-resistant materials to prevent accidents or damage to the glassware.
It is to prevent direct contact of the glass with the flame of the Bunsen burner. This lowers the possibility of the glass shattering when being heated Read more: What_is_the_purpose_of_the_wire_gauze_placed_over_a_bunsen_burner
A wire gauze is placed on a tripod stand on top of a Bunsen burner.
heat-restrictions
The yellow flame, with a temperature of max. 300 0C, is used only for the functionality checking of a Bunsen burner. The temperature is too low for heating in many experiments. This is also known as a Dirty flame because of its tendency to cause soot buildup.(you can see this phenomenon in a gas fireplace that is set too high.)
