Saturation Pressure

• A bench top unit comprising a boiler
  vessel and pipe loop with a pressure relief valve to limit the operating
  pressure to 8 bar gauge. A sight glass on the front of the boiler
  allows the boiling patterns to be observed and a Bourdon type gauge
  indicates the pressure in the apparatus at all times for safe operation.


• A throttling calorimeter mounted
  adjacent to the pipe loop allows the condition of the saturated steam to
  be determined by measuring the temperature of the steam following
  throttling to atmospheric pressure. Temperatures in the pipe loop and
  inside the throttling calorimeter are measured using PRT sensors and
  pressure in the loop is measured using an electronic pressure sensor.


• An electrical console houses the
  necessary electronics with current protection devices and an RCD for
  operator protection. A digital meter with selector switch displays all
  sensor measurements. Corresponding signals are routed to an I/O port for
  connection to a PC. An optional interface device and educational
  software package is available.


• The boiler is heated by a pair of 500 W electric heating elements with variable power control and over-temperature protection.


• A comprehensive instruction manual is included with a range of fully detailed Laboratory Teaching Exercises.

Key Features:

• Measurement of the relationship between temperature and pressure of the saturated vapour in the loop


• Convenient control of heat input to the boiler using variable power control


• Sight glass in the boiler allows observation of the boiling patterns in the water


• Safe operation with pressure relief valve and permanent indication of system pressure


• Pressure and temperatures measured can be logged using a PC (optional teaching software available)

Description:

A bench top unit designed to introduce students to the characteristics of saturated water vapour.

The apparatus consists of a rectangular
pipe loop incorporating a cylindrical boiler in one vertical limb. Pure
water in the boiler is heated to its boiling point using a pair of
cartridge heaters with variable power control. A sight glass on the
front of the boiler allows the internal processes to be observed, namely
boiling patterns at the surface of the water, and also allows the water
level in the boiler to be monitored. Saturated steam leaving the top of
the boiler passes around the pipe loop before condensing and returning
to the base of the boiler for re-heating. The operating range of the
boiler and loop is 0 to 7 bar gauge. The top limb of the pipe loop
incorporates a PRT temperature sensor and an electronic pressure sensor
to measure the properties of the saturated steam. A filling point on the
top limb allows the loop to be filled with pure water and allows all
air to be vented safely before sealing the loop for pressurised
measurements. A vapour off take, with isolating valve, allows steam from
within the loop to be passed through a throttling calorimeter, the
purpose of which is to demonstrate how the dryness fraction of the
saturated steam in the loop can be determined. The steam expands to
atmospheric pressure as it is throttled and a second PRT temperature
sensor measures the temperature of the steam following expansion
