While the normal gas flame can
only produce a “operating” to “light blue” type of flame, the Bunsen burner can
at least yield three types of flame. Consequently, the following:
Operating flame
– which is yellow/orange in color, near 300° C.
·
Blue flame –
can be imperceptible under normal lighting conditions, near 500° C. The typically
used laboratory type of flame.
·
Roaring-blue
flame – forms a triangular shaped in the center of the flame normally light
blue in color and interestingly, it’s a sound-producing flame. Heat is near to
700° C.
Imagine with this three kinds
of flame produced and a Bunsen burner creates compared to a simple normal gas
flame. In sense, the roaring-blue flame proves evident as to why Bunsen burner
is hotter hence, the amount of heat it makes (700°C) it makes.
