High-pressure steam generator does not require a certificate

Steam Turbines and Boilers - UNIRI

The steam does not 'blow the wheel around'. The shaping of the blades causes a change in direction and hence velocity of the steam jet. Now a change in velocity for a given mass flow of steam will produce a force which acts to turn the turbine wheel, i.e. mass

Steam and Condensate - A basic overview of a steam system - The Boiler House

Any steam using plant will require some method to control the flow of steam. A constant flow of steam at the same pressure and temperature is often not what is required - a gradually increasing flow will be needed at start-up to gently warm the plant, and once the process reaches the desired temperature, the flow must be reduced.

An introduction to steam generation and distribution

Trevithick was the first to successfully use high-pressure steam (then known as "strong" steam). Until ca. 1800, the weakness of existing boilers coupled with the influence of James Watt had generally restricted steam boilers to very low pressures or "weak" steam.

Deaerator - an overview | ScienceDirect Topics

Also, the HP bypass steam does not go to the turbine (it is instead returned to the boiler for reheating, hence the fear from water carryover is not there). However, in the case of large SC boilers, it is customary to take the SH temperature control spray flow from the economizer outlet because in those case, the MS temperature is higher (to avoid thermal shock).

Saturated vs Superheat Steam Conditions - Nationwide Boiler

Superheated steam has a lower density, so lowering the temperature does not revert it back to its original liquid state. Dropping the temperature of saturated steam, however, will revert it back to its old form of water droplets. Superheated steam has more energy and can work harder than saturated steam, but the heat content is much less useful.
