A GREAT SAVING EFFECTED 



At the Salpetre Works of Battelle & 

 Renwick, Jersey City, N. J., a novel steam 

 trap system has just been installed, which 

 takes care of the condensation from the 

 entire apparatus of the mill, and returns 

 the same to the boilers. Tnis system not 

 only provides for all the condensation, but 

 it is so arranged that the waste vapor from 

 the vents of the traps is also condensed and 

 returned with the condensate from other 

 sources. The mill apparatus consists of 

 nineteen special kettles for boiling. Each 

 kettle is equipped with what is known as 

 a pit coil, that is, the drip from the coil, 

 instead of passing through the bottom of 

 the kettle, is carried up over the edge, so 

 that the water of cendensation is raised 

 six feet before it is discharged. Drying 

 machines and a dry room are also included 

 in the system. The approximate amount 

 of steam required for boiling alone is about 

 600 h.p. The boiling point of some of the 

 liquids in the kettles is as high as 270 de- 

 grees F. ; therefore, live steam is required 

 for this work. On account of the form 

 of the coils, it has been found impossible 

 to use ordinary traps on this work ; each 

 coil at the present time is equipped with 

 a special No. 20 Lytton Trap which dis- 

 charges into one of the return mains, of 

 which there are two, running through the 



factory and back to a receiving tank in the 

 boiler room. The temperature of this re- 

 turn water varies from 2G0 to 2S2 degrees 

 F. The vapor from the special traps is 

 used for drying purposes, and when con- 

 densed is returned to the boilers, so that 

 no steam on vapor is allowed to escape 

 into the atmosphere. On the boilers are 

 located two 4-inch and one 1%-inch return 

 traps, which take care of the return water 

 from the factor^' at the temperatures men- 

 tioned and return it automatically to the 

 boilers. The condensation from the live 

 steam mains is trapped and collected in a 

 separate return, which discharges into the 

 receiver in the boiler room. By the instal- 

 lation of this system the saving in coal 

 alone amounts to 2\{i tons per day, while 

 the boiling capacity of a number of the 

 kettles is increased from 15 to 25 per cenr. 

 Tt has not only made a saving of coal and 

 increased the capacity of the kettles, but 

 it is feeding the boiler with about 90 per 

 cent of pure water, which prevents the 

 formation of scale and also makes a re- 

 duction in the amount of make-up water 

 purchased from the city. This system was 

 devised by D. J. Lewis, Jr., Hudson Ter- 

 minal Building, New York, sales manager 

 and trap expert of the Lytton Manufactur- 

 ing Corporation, and comprises 26 Lytton 

 Traps, 3 of which are return and the re- 

 mainder regular and special 20 series traps.
