Short answer: What is the basic principle equation for Claus sulfur recovery?
H2S+0.5O2=0.5S2+H2O 2H2S+SO2=2H2O+（3/n）Sn
The overall reaction: 3H2S + 1.5O2 = 3S + 3H2O can be broken down into: H2S + 1.3O2 = SO2 + H2O (1) and 2H2S + SO2 = S + 2H2O (2). Reaction (2) is the Claus reaction!

What are the basic principle equations for Claus sulfur recovery? Sulfur recovery is typically achieved using a process called the “Claus” process. Sulfur-containing feed gas is commonly referred to as sour gas. First, the acidic gas is burned with air or oxygen in a device called a combustion furnace. Strictly control the amount of air or oxygen to maintain a volume ratio of hydrogen sulfide to sulfur dioxide gases in the combustion products of 2:1. After that, the combustion gases are cooled, and the sulfur in the gases is condensed and recovered. The remaining gas is heated and then fed into a Claus reactor for reaction. The reaction mainly involves the production of sulfur and water from hydrogen sulfide and sulfur dioxide. This reaction requires a catalyst to take place. The gas after the reaction also needs to be cooled to recover sulfur. Then the remaining gas undergoes secondary and tertiary reactions. Typically, the sulfur recovery rate of sulfur recovery units can reach 95–98%.

H2S + 3/2 O2 = SO2 + H2O (1) 2H2S + SO2 = 3/Sx + 2H2O (2) Reactions (1) and (2) take place in high-temperature reactors; in the catalytic reaction zone (below 538°C), in addition to reaction (2), the following hydrolysis reactions of organic sulfides also occur: CS2 + H2O = COS + H2S (3) COS + H2O = H2S + CO2 (4)

The Claus process is widely used in industry to treat acidic gases containing H2S; the reaction equations are as follows: H2S + 3/2 O2 = SO2 + H2O (1) 2H2S + SO2 = 3/S X Sx + 2H2O (2). Reactions (1) and (2) take place in high-temperature reactors, while in the catalytic reaction zone (below 538°C), in addition to reaction (2), the following hydrolysis reactions of organic sulfides also occur: CS2 + H2O = COS + H2S (3) COS + H2O = H2S + CO2 (4)
(1) What is 1.3? But I understand what you mean; it must be a typo. . .
H2S + 3/2 O2 = S02 + H2O 2H2S + S02 = 3/X Sx + 2H2O

Its main reaction equations are: H2S + 3/2 O2 = SO2 + H2O + 519.2 kJ; 2H2S + SO2 = 3S + 2H2O + 93 kJ. Since acidic gases contain substances other than H2S, such as CO2, H2O, and hydrocarbons, the chemical reactions are very complex, with various side reactions occurring.
