Please discuss what the pressure is of low-pressure steam at 0.35 MPa after passing through the heater’s trap
It is related to the back pressure behind the steam trap; that is, it depends on the value of the back pressure. Of course, it will definitely be below 0.35 MPa.
A pressure gauge should be installed behind the desiccant trap, allowing for an easy assessment of the pressure level. Different manufacturers use different designs; the pipe diameters vary, and the discharge points of the steam condensers also differ, so it’s not possible to make generalizations. Installing a pressure gauge is the simplest and most straightforward method, with the pressure typically ranging from 0.1 to 0.2 MPa.
The pressure is generally around 0.1 to 0.2 MPa. If your steam system is capable of using steam within this range, you can send this portion of the condensate to the flash tank to generate steam there! To achieve energy savings and reduced consumption!
The problem is that our heater trap is on the first floor, and the condensate cannot return to the condensate tank on the second floor; the vertical height difference is about 8 meters
The heater trap for the low-pressure steam at 0.34 Mpa in the ammonia stripping process is located on the first floor, at a vertical distance of about 10 meters from the condensate tank. Moreover, the condensate tank also controls the pressure at 0.12 Mpa, and the condensate is discharged at a steady flow. Are you guys having poor heating performance, which leads you to suspect a drainage issue? It is recommended that you check for reasons such as the strainer and other aspects.
1. Is your strainer positioned at the very bottom of the heater, ensuring that no residual water remains inside the heater whether it is in operation or shut down?； 2. The pressure difference available for use is approximately 0.14 MPa, which is sufficient for a hydroseparator operating with a low pressure difference ； 3. Check whether there is any blockage in the steam trap piping; if so, remove it promptly ； 4. If conditions permit, measure the pressure values at the heater inlet and outlet, as well as at the steam trap inlet and outlet, in order to conduct analysis ； 5. Install a return water pressure booster.

That is mainly due to the back pressure of the steam trap; the inlet pressure is determined by the pressure of the heater, the temperature, and the installation height of the steam trap
The pressure inside the heater should be slightly below 0.35 MPa; otherwise, the temperature difference will be small and the heating temperature won’t rise. The pressure behind the steam trap should also be below 0.35 MPa, otherwise water cannot be drained and heat exchange cannot take place. The exact pressure level can be determined by checking the pressure of the water system. Wishing all marine friends a happy Labor Day.
The pressure is generally around 0.1 to 0.2 MPa.
Steam at 0.35 MPa, used as a heat source, generally flows into the condensate tank after passing through the steam trap; the pressure in the condensate tank is usually at atmospheric pressure or around 0.15 MPa, so the pressure after the steam trap does not exceed 0.2 MPa.
