Can an oxygen deficient volcano be directly covered with a steam engine

Oxygen Deficiency Volcano can be built directly with a steam engine. Oxygen deficiency steam turbine needs to meet the upper and lower pressure difference of 227 degrees of steam, just need to build the steam turbine above the volcano, and then pour water to the volcano can easily reach the steam value, and then through the equipment will be steam into the steam turbine can be launched. Steam turbines can also be used to generate electricity from water vapor, just modify it to generate oxygen.
