The effect obtained, then, from one
kilogramme of motive steam is, in round numbers, 5.5 kilogrammes of
steam removed from the juice.
It must not be forgotten that the motive steam was at the very moderate
pressure of 4 effective atmospheres. Had the use of steam at high
pressure (7 atmospheres for example) been possible, it is easy to
conclude from the above results that more than 6 kilogrammes of water
would have been vaporized with one kilogramme of steam.
The results here cited were ascertained by accurately measuring the
quantities of water of condensation from each evaporator, they soon
received, moreover, the most important of confirmations by the decrease
in the general consumption of fuel by the generators which occurred
after the new apparatus was set in operation.
The mean consumption of coal per 24 hours for the twenty days preceding
the 18th of November was 86,060 kilogrammes. After this date the regular
consumption was as follows:
