HEAT. 



CONDENSER FOR LAND AND OTHER STEAM-ENGINES. 

 BY C. W. SIEMENS.* 



MR. SIEMENS submitted and explained his condenser for land 

 and other steam engines. 



The action of the condenser is as follows : as the jet of steam 

 passes over the top of the condenser, water is forced through a 

 series of plates, and passes out at the top in a spray at the rate of 

 3 feet per second. When the water level falls below the bottom 

 of the plates, a jet of water is then thrown across the end of the 

 plates into the water well. 



The water level falls to its lowest point during about |th part of 

 the stroke of the piston ; during the last |th stroke the water is 

 driven upwards. 



The lower end of the plates of the condensers are about 150 of 

 heat, the upper portion are about 212. The ascending water 

 rushes out at a temperature nearly equal to the temperature of the 

 plates themselves. 



The gases are then carried into the hot well by the succeeding 

 jet of steam.
