What is the
primary function of a steam trap in a boiler?
Recover heat
from exit gases
Increase
temperature of steam above saturated temperature
Separate the water particles from the steam
Drain
off condensed water accumulating in the steam pipelines
Drain
off condensed water accumulating in the steam pipelines
● Steam
traps are a type of automatic valve that filters out condensate (i.e.
condensed steam) and non-condensable gases such as air without
letting steam escape.
● In
industry, steam is used regularly for heating or as a driving force
for mechanical power.
● Primary
function of a steam trap in a boiler is to drain off condensed water
accumulating in the steam pipelines.
Hence, the correct option is (D).
&Key Points:-
● Steam
traps can be split into three main categories, mechanical, thermodynamic and thermostatic.
● Each type uses
a different operating principle to remove condensate and
non-condensable gases and keep steam in the system.
