The question is not precise enough: What is the compliance level for the boiler? Is the full output of a single steam turbine 7MW? It’s hard to answer.
It’s necessary to see how the system operates before a reply can be given.
I’m sorry. The boiler is 75 tons. The turbine is 12.5MW. The electrical load mentioned above is determined based on the operation status of the electrolyzer. Gas is also supplied externally. It is powered by a pull to supply air. There is also some gas usage within the factory, but the amount is relatively small. That’s roughly what the situation is like.

Both steam turbine generators have an output of 7MW each, with a rated output of 12.5MW for each generator. Can the electrical demands be met if only one generator is used? Clearly, the output of one generator is not sufficient to reach 14MW, so there is no issue related to cost efficiency. Another possibility is that your plant has access to external electricity as a supplement. This type of situation requires detailed analysis using various parameters, such as the parameters of your boilers, main steam conditions, turbine parameters, parameters of the first extraction steam, parameters of the second extraction steam, the demand for first extraction steam, the demand for second extraction steam, overall electricity needs, and whether there is grid electricity available as a supplement
