Check this out, it might help. It will depend on the gas being combusted.
Some Calculated Adiabatic Flame Temperatures*
Absolute temperature (K)
Acetylene in air 2,600
Acetylene in oxygen 3,410
Methane in air 2,232
Methane in oxygen 3,053
Hydrogen in air 2,400
Hydrogen in Oxygen 3,080
Heptane in air 2,290
Heptane in oxygen 3,100
WTF is the thumbs down for? If you don't know what us intelligent people are talking about, go play with your leggo and try not to swallow any...!

The design of a Bunsen burner includes a vertical metal tube which is connected to a weighted base. The base includes a nozzle to connect with a fuel source, as well as a gas valve and a flue adjuster to control how much air is admitted through small air holes at the base of the tube. The gas mixes with air at the bottom of the tube and then rises to the top of the Bunsen burner, where it can be lit with a match or lighter. A scientist can either hold something in the flame with tongs, or set something onto a sturdy stand designed to be used with a Bunsen burner. Like many ubiquitous scientific inventions, the Bunsen burner reflects the name of the scientist supervising the lab where it was invented, rather than the actual inventor. Robert Wilhelm Bunsen was a well known chemist in Germany in the mid 1800s, searching for a way to provide clean, safe heat in his laboratory. One of his laboratory assistants, Michael Faraday, invented a gas burner to assist them with experiments, and another lab assistant, Peter Desaga, refined the invention, calling the result a Tirrill burner. This burner allowed for greater control over the flame's height and intensity, and it quickly became associated with Bunsen's lab. As a result, it became popularly known as a Bunsen burner.

There are three layers of flame in a Bunsen burner. The outermost is the coolest one, with temprature around 200, middle layer is around 400, and inner-most (sometimes called core) is hottest, at around 1000 degrees.

there are three region of flames in the flame of Bunsen burner, the hotest region is the core ( the center of flame,) and the temp. lowered at the second and third regions respectively,
the temp. of each region depends on the fuel used (gas mixture)
just for uer knowledge , the name of the burner is on the honor of its inventor , Bunzen

about 1000 degrees depending on where in the flame you're talking about. it was the source of someones thesis in the 1890s so there are graphs out there

The hottest part is the small bright blue triangle in the centre, which is 1000 degrees centigrade.

I think it is unburned gas. Can't remember. Anyway the colourless flame is the hottest.
