Where is the highest temperature and where is the greatest heat produced in a neutral oxyacetylene flame?

To determine

The location of highest temperature and greatest heat produced in neutral oxy-acetylene flame.

Explanation

There are three types of oxyacetylene flame oxidizing flame, neutral flame, and carburizing flame. Neutral flame produced by mixing oxygen and acetylene is equal quantity in ratio of 1:1. Neutral flame does not make any chemical reaction in the metal. It acts as a shield to protect the weld pool from open atmosphere. This flame burns at temperature approximately 5589°F. As highest temperature of neutral flame is found at inner cone the greatest heat also produced at the inner cone of the flame.

Oxidizing flame produced when the supply of acetylene is reduced in the neutral flame, it is shown by ratio of 1.5:1. As the quantity of oxygen increases the flame becomes shorter
