Oxygen Lance - an overview | ScienceDirect Topics
Each of the individual acid gas burners consists of three concentric lances: an inner oxygen lance, a middle acid gas lance, and an outer process air lance. This configuration results in a very hot oxygen flame with a core temperature of over 2000°C which is enveloped by a cooler air/acid gas flame.

Today, calcium metal is usually prepared by electrolysis of fused calcium chloride to which a little calcium fluoride has been added. It is used in alloys with other metals, such as aluminum, lead, or copper; in preparation of other metals, such as thorium and uranium, by reduction; and (like barium) in the manufacture of vacuum tubes to remove residual gases.

When a metal reacts with dilute nitric acid, then hydrogen gas is not evolved. ( Nitric acid is a strong oxidizing agent , so, as soon as H 2 is formed the nitric acid oxidizes it to water.) Very dilute nitric acid reacts with magnesium and manganese metals to evolve hydrogen gas.
Calcium - 3D Elements
The chemistry of calcium is that of a typical heavy alkaline earth metal. For example, calcium spontaneously reacts with water more quickly than magnesium and less quickly than strontium to produce calcium hydroxide and hydrogen gas. It also reacts with the oxygen and nitrogen in the air to form a mixture of calcium oxide and calcium nitride.
