Seeking advice on turbine extraction issues

Industrial extraction steam: Normal: 1.0 MPa; Maximum: 1.3 MPa; Minimum: 0.8 MPa. Extraction steam flow at rated power: Normal: 50 T/h; Maximum: 80 T/h (at an extraction pressure of 1.0 MPa). Does this extraction refer to regulated extraction? Is adjusting the exhaust volume equal to the exhaust for heat supply (into the pipeline network or for user use) + the exhaust for heat recovery? ? This extraction steam refers to the control extraction steam; this stage of extraction steam is supplied for use by industrial heat users. A portion is also used for heating feedwater with high-pressure heaters, and it serves as steam for regenerative heating.

Why go through such pain, original poster? First, you need to clarify these procedures; take a look at the blueprints and then go through the processes – it will be much clearer that way. If that doesn’t work, take some photos and bring them back for everyone to review. As for whether heat recovery steam extraction is included or not? I think I’ll just need to look at the process to find out. Generally speaking, this is purely a matter of speculation; rather than creating additional openings in the turbine casing, it’s better to draw steam from the extraction pipeline. In short, there should be a flow meter on the extraction pipeline, and the amount of steam extracted should represent the total volume. The reheat steam is simply drawn from the extraction network, and since control is achieved by regulating the temperature of the boiler feedwater, a temperature controller is sufficient – a flow meter is likely not necessary.

That is for regulating the extraction steam; the amount of extraction steam equals the amount of steam supplied from outside. Excluding the steam turbine reheating extraction volume
