What is the purpose of the baffle behind the exhaust gas incinerator?
Thread Content
May I ask everyone, 1) Are there any flue dampers or valves, or other control components, before the chimney at the back of your exhaust gas incinerator? 2) When are baffles generally used? What purpose? 3) Removing the baffle – do you think that’s appropriate? How great is the risk? Thank you!
In the past, when lighting the stove with a torch, the baffle was used to reduce the suction in the chimney; otherwise, the excessive negative pressure would blow out the flame of the torch. Although electric igniters are used now, they can also fail from time to time. In the past, Qilu would increase the system pressure by closing small dampers in order to raise the conversion rate of the device. It is estimated that no other company uses this approach. However, this reminds me that the pressure in the furnace for the sulfur treatment ahead of us is very low, at only 6 kPa. As a result, the pressure of the process gas and exhaust gases is too low, making it impossible to collect samples. I’ll discuss this with them later to see if we need to reduce it We used baffle plates before, but now we use butterfly valves; they are also used behind the sulfur production furnace.
What we have doesn’t have any partitions, and I think the purpose of partitions is to maintain a certain positive pressure inside the furnace.
1. The suction force of a chimney is quite strong; such high suction force, or a positive pressure during ignition, makes it difficult to start the process. 2. It is necessary to control the pressure throughout the entire system. A certain level of pressure is required in the cooling system in order to reduce the partial pressure of sulfur and prevent sulfur from clogging the equipment pipelines
