Why are check valves installed on continuous discharge pipes? Thank you for the advice!
There is no check valve on the continuous blowdown pipe of our waste heat boiler, so it should not have a significant impact. After all, the pressure of the medium inside the drum is much higher than that inside the serial expansion device.

When there is only one waste heat boiler, the absence of a check valve does not have a significant impact. But when there are multiple boilers, it is necessary to prevent the drain water from the boilers that are in operation from entering other boilers that are either on standby or under maintenance.

It is necessary to install check valves; without them, when several boilers share a common drain pipe, they will affect each other.

It has been learned that, in order to prevent steam from other pipelines from flowing back into the collective drain branch pipes and to reduce unnecessary water shock, it is necessary to use check valves as safety devices in operating equipment.
It’s necessary; if multiple units are used, problems can arise if it’s not installed, so it’s a good way to eliminate potential safety hazards.
There are only advantages to installing it, no disadvantages; the only thing is that it costs a bit more money.
