   A section through Zibold's dew condenser. (a) is a truncated cone of beach pebbles 20 metres (66 ft) in diameter at the base and 8 metres (26 ft) in diameter at the top. (b) is a concrete bowl; a pipe (not shown) leads away from the base of the bowl to a collecting point. (c) is ground level and (d) is the natural limestone base. [11]

5. Condensing boiler - Wikipedia

   en.wikipedia.org/wiki/Condensing_boiler

   Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.

9. Condenser (laboratory) - Wikipedia

   en.wikipedia.org/wiki/Condenser_(laboratory)

   The two hoses connected to the condenser circulate water through the space between the inner and outer walls. In chemistry, a condenser is laboratory apparatus used to condense vapors – that is, turn them into liquids – by cooling them down. [1] Condensers are routinely used in laboratory operations such as distillation, reflux, and ...
