Abstract

337,302. Taglietti, U., and Tasso, A. Jan. 29, 1929, [Convention date]. Heating by circulation of fluids.- In a condensate collecting apparatus communicating with a number of groups of steam heaters each group working at different pressures on the closed cycle system and connected to independent collectors, the latter release their excess steam or discharge excess condensate to a heat accumulator. The collector of the low pressure group works as a continuous discharger of the accumulator. The steam heaters 1-1 - - 3-3 working at high, medium and low pressures discharge their excess steam and condensate to the collectors B<1> - - B<2>, respectively, from which the liquid is pumped to the boiler by the pumping apparatus 30 - - 32. Excess condensate passes from B<1> and B<2> to the accumulator P through pipes 18, 19 and excess steam through safety valves VS', VS<2> to the same reservoir. The low pressure collector B<3> and the accumulator are at the same pressure, condensate discharging from the latter to the former, which also receives excess condensate and steam from the low pressure group 3-3. The pressure in the latter is kept beneath a suitable limit by adjusting the pressure in the accumulator. This may be effected by automatic iniection of cold water under pressure into the accumulator, the supply being controlled by a valve actuated by the pressure existing in the accumulator; or by combining with the accumulator a tubular heat exchanger having cold water circulating through the tubes; or the accumulator may work as an intermittent steam generator or as a continuous generator in a secondary steam heating plant. Specification 295,104, [Class 102 (i), Pumps &c.], is referred to.
