FEED WATER HEATER 



THE Linton Combination Feed-Water Heater, 

 Purifier, Oil Separator, Muffler, Return 

 Tank and Pump Governor, installed in the 

 Singer Building, performs all the functions indicated 

 by its title. 



It is primarily an "open" feed-water heater, is of 

 the horizontal type and is 72 inches in diameter and 

 144 inches long. The exhaust steam inlet and out- 

 let connections are 20 inches in diameter. This 

 Combination contains some new and improved 

 features, especial attention being given to the satis- 

 factory separation of the oil from the exhaust steam 

 and for accessibility to the interior. The exhaust 

 steam upon entering is introduced into the large 

 expansion chamber where its velocity is greatly re- 

 tarded, from there it passes through a perforated baffle 

 plate where it is broken up, and thence through the 

 separating screens. These screens are of ^-inch wire 

 mesh and thoroughly remove all oil in the exhaust 

 allowing it to be used in the heating system of the 

 building and the returns from same to be taken back 

 to the heater and from there into the boilers. The 

 oil is drained off to be re-used and the steam passes 



on, over and around the heating trays where it mingles 

 with the feed water, heating it to its temperature, 

 212 F. A perfectly tight diaphragm prevents the 

 liberated oil from coming in contact with the feed 

 water. The entire heads of the Combination are re- 

 movable without disturbing any connections, which al- 

 lows the whole interior to be readily examined and the 

 trays, filter box and screens to be easily removed, mak- 

 ing it the most accessible of any heater manufactured. 



As the returns from the heating system of the 

 building form a considerable part of the feed water 

 but little fresh cold water is introduced. The feed 

 water passes from tray to tray in opposite directions 

 and from there into the filter box where it is filtered 

 through coke and looses any foreign matter that has 

 already been deposited on the heating trays. It is 

 then pumped to the boilers, this being automatically 

 controlled by the pump governor, a part of the Com- 

 bination, consisting of a special balanced valve oper- 

 ated by a copper float. 



The Linton Combination is manufactured by the 

 Linton Machine Company, No. 26 Cortlandt Street, 

 New York City.
