Separating and Throttling Calorimeter With Boiler
Made in our own plant in Ambala Cantt, the Separating and Throttling Calorimeter With Boiler is supplied to colleges, technical institutes and industry for thermal engineering work, in single units or bulk. Part of our Thermodynamics Lab range.
Aim
To find out dryness fraction of steam by combined separating and throttling calorimeter.
Product Details:
The steam passing out from separating calorimeter may still contain some
water vapour , in it . in other words it may not be absolutely dry .
again , in a throttling calorimeter steam after passing through the
throttle valve must be superheated or at least dry saturated . this
limits the extent of dryness fraction that can be reliably measured ,
depend up on the pressure of steam in the main steam pipe . if a sample
of steam, which may be still wet after passing through the throttle
valve i.e it will not be superheated . thus under this condition the
throttling calorimeter fails to enable us in determining the value of
dryness fraction of steam . to overcome this difficulties we make use of
separating and throttling calorimeter . first the steam is passed
through separating calorimeter where itlosses most of it's moisture and
becomes comparatively drier, it is than passed through the throttling
calorimeter where super heating takes place with out changr of total
heat . the temperature and pressure of steam after throttling are
measured by using a thermometer and manometer respectively.
Description
The set up consist of a separating and throttling
calorimeter . a steam generator is provided at the base of the apparatus
. a thermostat knob is provided at the front of apparatus to control
the temperature inside the steam generator . steam from steam generator
is passed from separating calorimeter where most of the water partical
get separated from steam and then passed to throttling calorimeter where
steam get superheated . after that superheated steam passed through
heat exchanger to condense the steam.
Separating Calorimeter
It consist of two concentric chamber , the inner chamber
,and the outer chamber . which communicates with each other through an
opening at the top. As the steam discharge through the metal baskets
,which has a large number of holes , the water partical due to there
heavier momentum get separated from the steam and collected in the
chamber. The comparatively dry steam in the inner chamber moves up and
than down aging through the annular space between the two chambers and
enters the throttling calorimeter .
Throttling Calorimeter
It consist a narrow throat . pressure and temperature are
measured by manometer and thermometer . the steam after throttling
process passed through the heat exchanger and condensate is collected .
