It is used to determine whether a certain gas or gas mixture can be burned in a torch
Thread Content
As the title suggests, I’m an EHS professional. I would like to ask everyone how to determine whether a particular gas or a mixture of gases can be burned in a flare, when designing the system for discharging waste gases into such flares. Are there any specific formulas for this? And if a gas cannot be ignited directly, how can we determine whether it can be ignited with the help of an oxidizing gas? I am extremely grateful.
1. For the combustion of a torch, as long as its calorific value is around 7880 KJ/Nm3, stable self-combustion can be ensured. If the calorific value is lower, an oxidizing gas can be introduced to maintain the torch’s combustion. 2. Whether several mixed gases can be discharged into a single flare simultaneously needs to be determined by taking into account factors such as composition, temperature, and pressure, to ensure that no chemical reactions occur that could lead to crystallization. For example, acidic and alkaline gases are not suitable for being discharged into the same flare; they should be burned in separate flares. Of course, the calorific value of each stream of gas fed into the flare must meet the requirements specified in point 1 above
