In steam boiler systems, a large amount of steam is still released despite the recovery of condensed steam

After the steam is used by customers, it is condensed and recovered. However, recently a large amount of steam has been escaping from the exhaust pipes of the steam recovery system. We’re not sure what the problem is or what could be causing it; we would appreciate it if a professional could take a look at it. Thank you!
Regardless of why steam is being released, there’s a serious problem with that discharge pipe of yours, bro
How should I put it? Please advise; we’re not familiar with this either
It is estimated that the pressure inside the condensate recovery unit was too high, so the safety valve activated to release pressure; in our plant, water is directly delivered to the boiler at the appropriate water level
On the surface, it seems that the condensation effect is not satisfactory; it’s unclear whether the refrigerant isn’t functioning properly, or if the operating load is higher than the designed level. Another possibility is that the area available for heat exchange is insufficient, which results in poor heat exchange efficiency.
Steam condensation equipment doesn’t seem to have any refrigerant, just a few tanks, right? I guess their load is too high; the condensation equipment can’t handle that much steam, so it all gets released. But this didn’t happen before – could it be due to the colder weather?
On this side, it goes from the condensation recovery unit into the water tank, and then to the boiler
It is best to install a vertical circulating water cooler at the steam outlet to reduce steam emission, with the condensate being directly recycled back into the tank. Steam is more noticeable in winter.
1. The heat exchange area is too small. 2. The burning intensity is too high. 3. The power of the circulation pump is excessive, causing overpressure in the system; as a result, the pressure relief device on the tail end activates on its own
First of all, thank you for the reply! There wasn’t such heavy exhaust emission from his side before; it was a sudden occurrence, and then things improved. I don’t know what caused it, and no problems were identified either.\ud83d\ude05
