generator turbines to seal the shaft glands against leakage. This leakage includes air leaking into the turbine  casings  and  steam  leaking  out  of  the turbine  casings.  More  use  of  electrically  driven (rather   than   turbine-driven)   auxiliaries   has simplified auxiliary steam systems on newer ships. SUMMARY In  this  chapter,  you  have  learned  about  the main steam system, the auxiliary steam system, and  the  use  of  steam  after  it  leaves  the  boiler. Remember,  steam  and  feedwater  are  recycled  over and  over  again  to  provide  heat  and  power  to operate   machinery.   It   is   important   that   you understand  the  terminology  associated  with  steam and feedwater systems. You will use these terms in your day-to-day routine aboard ship. Some of the subjects will be discussed in greater detail in later  chapters.  All  of  these  areas  are  important in their own right. As you learn this information, you  will  become  a  more  proficient  and  reliable technician. 3-6
