Marcet Boiler Test Setup
Product Code : EL-TELE-10712
Quick Answer: The Marcet Boiler Test Setup is an experimental closed system filled with fluid in which a thermodynamic equilibrium forms between the fluid and its vaporized phase, with the prevailing pressure known as vapour pressure. It lets students observe how, when a fluid is heated in a closed tank, pressure rises with temperature, and it demonstrates the pressure-temperature relationship of water up to temperatures of 200°C. The unit is fitted with digital temperature and Bourdon tube pressure gauges plus safety devices, making it a straightforward way to record the vapour pressure curve.
In the Marcet Boiler, an experimental closed system filled with fluid, a thermodynamic equilibrium sets in between the fluid and its vaporized phase, and the prevailing pressure is called vapour pressure; it is substance-specific and temperature-dependent. When a fluid is heated in a closed tank, the pressure increases as the temperature rises, and theoretically this pressure increase is possible up to the critical point at which the densities of the fluid and gaseous phases are equal, beyond which fluid and vapour are no longer distinguishable from each other. This knowledge is applied in practice in process technology for freeze-drying or pressure-cooking, and temperatures of up to 200°C are possible for recording the vapour pressure curve.
The temperature and pressure can be continuously monitored via a digital temperature display and a Bourdon tube pressure gauge, while a temperature limiter and pressure relief valve are fitted as safety devices to protect the system against overpressure. The experimental unit can be used to demonstrate the relationship between the pressure and temperature of water in a straightforward manner.
