How many tons of steam are required to drive a 11,000 kW motor using a turbine?
Thread Content
Our company’s air separation compressors are electric-driven units, and we plan to convert them to be driven by steam turbines. How many tons of steam with a pressure of 3.6–3.82 MPa and a temperature of 415–430°C are required? How is it calculated?
Does your turbine use a condensing type or a back-pressure type? For a condensing type, around 55 t/h is required; with a back pressure of 1.0 MPa on the back pressure machine, about 165 t/h is needed
First, determine the enthalpy value of steam at 3.82 Mpa/430℃. Next, identify whether the turbine selected is a fully condensed type, a extraction-type turbine, or a back-pressure type; find the enthalpy value of the steam exiting the turbine, calculate the enthalpy difference δH between the inlet and outlet of the turbine, and then use the formula M*δH* η/3600=11000 to determine the steam flow rate in KG/H, where η represents the thermal efficiency, which is typically between 0.85 and 0.9
