Three key factors affecting the ammonia burning efficiency in sulfur production furnaces
Thread Content
Three key factors affecting the ammonia burning efficiency in sulfur production furnaces: 1. Temperature of the sulfur production furnace: above 1250 degrees. 2. The acidic gas is thoroughly mixed with air in the sulfur production furnace. 3. The optimal response time is generally kept between 16-20 seconds.
A residence time of 16-20 seconds? Where is this design from? Typically, the residence time in the reaction furnace of a sulfur recovery unit is 1–1.5 seconds.
It is partially introduced in Qilu’s \"Special Issue on Sulfur Recovery Technology Papers\".
The so-called residence time refers to the time spent in the reaction reactor; if the residence time is 16–20 seconds, then the reaction reactor will have to be very large.
The residence time is 16-20 seconds – is that too long? Today, ammonia burning processes use ammonia burners, so the residence time inside the furnace is not that long.
At 1200℃, the equilibrium concentration for ammonia decomposition is 40 ppm; to ensure effective ammonia decomposition, it is best to use vortex burners of German manufacture (as used by Liaoyang Refinery), as air distribution cannot be used for adjustment
16~20S is unlikely; this figure is incorrect
The residence time is a little over 1 second; it’s impossible to reach 20 seconds
