The process of evaporation in heated pipes that occurs in water-tube boilers can be demonstrated. The different phases that appear during evaporation in the pipe can be clearly seen.
The double-wall glass evaporation pipe allows the evaporation process to be observed closely. Hot water flows through the outer pipe and evaporates the medium in the inner pipe. The non-toxic liquid used starts to evaporate at 40 to 50°C. Low system pressures can be generated with the built-in water jet pump.
The pipe systems are clearly laid out on a metal panel. The hot water circuit consists of an expansion vessel, a circulating pump and heater. An evaporation pipe, vapour collector, water-cooled condenser and return pipe form the evaporation circuit.
