A "water based" glycol smoke generating apparatus in which a flattened fluid conduit (2) is held against a heat sink or between a pair of plates (4) forming a heat sink. Preferably an expansion chamber (5, 22) is provided at one or both ends of the conduit which is preferably formed in a snake-like form. A thermostatized heater (20) is provided to raise the heat sink temperature and a pump (31) or other pressure source (33) can be provided to force fluid through the apparatus. The flattened shape of the conduit makes good contact with the heat sink and the expansion chamber(s) aim to prevent "spitting" or high back pressure. |
