How much power is generated

100 kilograms of steam at 300 tons per hour, with a back pressure of 35 kilograms of steam – how many KW of power can be generated?

Generators of different sizes and formulations have varying efficiencies, as well as different power generation capacities. Only those who have experience with power generation know this empirical data

For industrial boilers of the 10MPa class, the typical main steam parameters are: pressure of 10MPaG and temperature of 540°C. Should we keep the steam parameters hidden and create a mystery? Are you using saturated steam to generate power? ? Steam of this level is used in back-pressure steam turbines for power generation; the overall efficiency of the turbine plus generator can reach around 78–83%. The steam consumption is approximately 13–14 kg/kWh. Roughly calculating: 300/14 = 21.4 MW. After accounting for the energy used for circulating water, which is about 100 kW, plus the electricity consumed by the turbine itself, which is around 200 kW, that accounts for roughly 0.4 MW. So, two thousand kWh of electricity can be generated per hour – is that sufficient? ?
