Question

In order for a high temperature boiler or steam engine to produce superheated water, or steam: the heat source must be greater than 100°C the water must be permitted to evaporate quickly the system must be sealed and become pressurized above atmospheric pressure the vapor pressure must be kept below 760 mm(Hg)

Answer 1

the system must be sealed and become pressurized above atmospheric pressure

Answer 2

Answer:

Superheated steam is a steam at a temperature greater than its vaporization or boiling point at the absolute pressure at which the temperature is measured.

In a high temperature boiler or steam engine,in order to produce superheated steam the heat source must be above 100°C and water must be allowed to escape the system quickly, and system should be sealed and pressure should be above atmospheric pressure and the pressure of vapors must be below 760 mm(Hg).

In the conditions described above the steam engine will produce super heated water.
