Not illustrated. 1908 edition. Excerpt: ...of a tubular reheater, the surface of which is based on the size of the extract factory, but which should not, in any case, exceed 10 square metres. It is, moreover, fitted with branch pipes, which connect it, on the one hand, with the escape collector of the autoclaves, on the other hand, with the condenser-reservoir properly so called, consisting of a copper beck with calandria, on which an emulsifier of the author-s construction is fixed, the whole about 1,000 litres (220 gallons) capacity. This plant, so fitted up, is placed at the upper level of the feed tank, into which the condensed water runs. To show the advantage it realises, it may be stated that in addition to the water, which it heats from 95 to 98 C. (203 to 208 4 F.) (without taking into account that utilisable (122 to l.31 F.), which not having been in contact with the tannic steam may be used to feed the boilers), it condenses almost entirely the whole of the escape steam from a battery of autoclaves of 60 tons capacity, the condensed water from which amounts to 12,000 to 14,000 litres (2,640 to: !,080 gallons), which again re-enter into the maceration work with a complement of ordinary water which exactly serves for the proper condensation, by emulsion, of the escape vapours, without fear of counterpressure or of the return of water to the autoclaves. All the pipes and manholes can be dismantled easily and readily for inspection or cleaning, without any stoppage of the factory, so as to keep the condensation capacity of the plant constant.
