Issues with the common drum in two newly installed boilers of different types
Thread Content
A set designed for a solid-water medium, in the form of a heat pipe boiler； Another set of media is flue gas-water, for flue-tube boilers. Both sets produce saturated steam at 2.4 megapascals. The original design called for two steam drums, but it has now been changed to one steam drum. What problems could this cause?
I think it is feasible to install check valves on each intake pipeline (in front of the steam drum); otherwise, pressure differences could cause backflow.
There is only one steam drum now； No backflow of vapor will occur
I would worry about uneven gas production； Therefore, the rising and descending pipes are independent of each other
If the feedwater is not independent, there may be feedwater deviation； An appropriate pipe diameter can be selected.
