How to determine the inlet steam flow rate of a turbine with exhaust backpressure?
Thread Content
We need an exhaust-backpressure steam turbine to drive the air compressor, with the following specific parameters: Power: 6800 KW; inlet steam pressure: 4.5 Mpa at saturation； The export process requires two types of steam: 1.8 Mpa steam at a rate of 10 t/h (for exhaust) ； The rest is 1.0 Mpa steam (back pressure). All require steam, with no condensate water produced. To achieve this operating condition, what is the required steam inlet flow rate for this turbine? How is it calculated? What is the steam consumption of this turbine? (KG/KW)
Please, all the experts, come and give some guidance! !
The relevant design manual should be available! I learned it in school, but I don’t need it now; I’ve long forgotten it.
I had no prior exposure to this kind of thing. I was wondering if there are any experts from thermal power plants who could provide me with a set of your actual parameters. Thank you so much! ! !
Our facility has a fan driven by an exhaust-backpressure type turbine, with the following design parameters: Power: 1930 KW; inlet steam pressure: 3.5 Mpa; flow rate: 29.2 tons per hour； Two types of backpressure steam are exported: one is 1.7 Mpa steam at a rate of 9.6 t/h ； The remainder is 19.6 tons per hour of 0.3Mpa steam.
Hello! Thank you so much for your data! Are these data purely for design purposes? Has it already been verified in actual production operations? Or what are the actual operational data? During design, how is the amount of inlet steam determined?
