Question

Prior to starting a small non-condensing steam turbine you must ensure that the _________ is at operating pressure:

Select one:
a. cooling water
b. boiler
c. oil sump
d. steam header

Answer 1

Before initiating the operation of a non-condensing steam turbine, it is imperative to check that the steam header has reached the necessary operating pressure to properly drive the turbine.

Step-by-step explanation:

Prior to starting a small non-condensing steam turbine, you must ensure that the steam header is at operating pressure. The steam header is a component of the system that collects the steam produced in the steam generator (boiler), and provides a reservoir of steam at the correct pressure and temperature to feed the turbine. Once the steam has passed through the turbine, generating power, it is converted back to water in the condenser. This condensed water is then returned to the steam generator to repeat the cycle. It is critical that the steam header is at the correct operating pressure to ensure that the steam can flow through the turbine effectively and safely to generate electricity.
