 more or less than a eomt)lnation of the prin- 

 eiples of the jet eondcMiser and the MorelH'ad 

 iiiitoniatie reliirn steam trap. 



Conneeted to the return line of vaeiiiim heal 

 ing systems where a difference of pressure is 

 maintained between tlie ends of the system the 

 line condensation and aeeiimnlating air is talteu 

 into tlie tank of the condenser trap as in the 

 ease of the return trap, but with the added 

 pullin); power of the vacuum created in the tanis 

 I't' tlu' condenser trap. 



\\'lii'n Mk- steam is Ivirned on in llie beating 

 system, the variovis lines of which are full of 

 air. tlio cold water supply valve, as sliown in 

 the scctiimal view of the trap, is opened siiKlitly. 

 As the condensation from the return lines and 

 the condensing water tills the tank, tlie latter 

 lilts, opening the live steam valve, allowing 

 ilie steam pressure to enter and discharge the 

 water contents into a return steam trap abovi^ 

 the boiler or into an op<'n heater. 



As soon as the water is discharged the tank 

 containing the steam which is left after the 

 v.ater is discharged, resumes a horizontal or 

 tilling position. The tank i-etui-ning to its liori- 

 zontal position automatically opens the control 

 valve on the cold water inlet and allows tlic cold 

 water spray to come iu r (nitact witli tlie live 

 -team contained iu the tank. This I'old water 

 roudenses the steam and forms a vacuum in the 

 tank of the trap, wliicb in turn performs the 

 usual functions of creating vacuum in heating 

 systems, of ijulling the cundi'iisation from ilie 

 lines to lie drained. 



The cold water supijly is furnished either from 

 ' ity water works, or a tank, or any other source 

 tliat is available for that luirpose. I'artieular 

 aitenlion is called to the fact that a surprisingly 

 small amount of water is reipiired in ttjc con- 

 densing process. 



A i-eceiver is always used iu coniU'ction with 

 ibe condenser trap, tile water seal in the re- 

 Miver taking llie place of thermostatic valves on 

 the heating system. The condenser trap is used 

 as the lower trap, taking the place of the return 

 trap in the Morebead standard double trap in- 

 stall. ition. the lower or condenser trap discharg- 

 ing to the return trap placed above the boiler. 



As the study of a typical installation is the 

 more interesting and convincing method of de- 



scribing the winkings and advantages of the 

 new condenser nap. Ibe inslallation at the K-M-K 

 Motor Car Company of I'ort Huron, Mich., is 

 leferred to and lllnsiraied herewith. 



The plant .if lb.' K-M.K .Motor Car Company 

 is a twoslory brick siruciure, e(|uipped wilb a 

 large exteni of glass .-irea for ijrofuse day light- 

 ing. Kiectric powi'r from an outside source 

 being used exclusively for operating the faclory 

 a special \2T> II. r. boiliu- was insialb-d for 

 lieating purposes. On (op of Ilie boiler is located 

 a No. 4 Morebead steam trap and boiler feed, 

 receiving tiii- condensation irom the No. 4 More, 

 head condenser trap, siluali'd alongside of the 

 boiler cm Ibe Jliior of the boiler room. Hnder

the tloor al a <le|ilh of .-iboiil live feet is the 

 receiver connecting the reluin lines and tlie 

 condenser trap. 



The piping in the entile system is equivalent 

 to (iO.OOci feet of 1-inch pipe. The main supply 

 pipe is brought up to make an overhead feed, 

 using wall coils throughout tlie factory and cast 

 iiiui radiation in Ilie ofhi'e. The boiler room 

 and iitllce are loiati il al extreme ends of the 

 plant. 



The returns from all the radiattus run along 

 the first floor. When a door Is reaclieii the pipe 

 is carried under the door and brought back to 

 the floor, thus forming a pocket and providing 

 no fall whatever In any of the return lines. 



The retui-ns before reaching the holler house 

 are gathered Into one :!-lnch main return pipe, 

 whicli carries the condensation to the recelv<'r 

 located in the pit below the condenser trap. 

 l*'rom the receiver the condensation Is drawn 

 into the condenser trap; thence lifted to the re- 

 lurn trap on top ot the boiler, which !n lurn 

 discharges It into the boiler. The distance In 

 height belw(!en tlie two traps Is about 13 feci, 



A pressure of from \LT> to -M pounds is car- 

 ried on the boiler and reduced to one and one- 

 half pounds on the system. With this Initial 

 lu-essure of one and on*.'-lialf pounds the con- 

 denser trap is pulling a vacuum ot !'.'> Inches. 



During a test run In zero weather this plant 

 was operated for •!?• successive hours on three 

 ions of .Saginaw slack coal, a highly economical 

 performanic according to the management of 

 Ibe plant. They further state that there was 

 not a minute's trouble or even the expense of a 

 cent connected with the working of the traps 

 during Ibe entire winter jjerlod. To- one ac- 

 nualnted with llie care and operation of steam 

 liaps. it is of interest to know ihat during the 

 fcregoing inentioned period not a piece of pack- 

 ing was put into either machine, the return trap 

 or tlie I'ondenser trap. 



At this writing the Morebead condenser trap 

 system is being installed In a number of the 

 large textile mills located in the New Fngiand 

 district. 



In addition 1o the foregoing inentioned typical 

 installation. Ibe 'condi'iiser trap has been siic- 

 eessfully apiilied to reduc-r'd pressure and exhaust 

 lieating In connection with fan ventilating and 

 beating systems and dry kilns. In every case 

 there has been shown a reduced consumption of 

 steam, an Increased erttclency In the systems and 

 an especially marked reduction in the coal bills. 



The condenser trap ™as tried out successfully 

 during all of lasi winter in the Kort Wayne 

 High School al I'lUi Wayne. Ind. The Maiimee 

 liriek & Tile Company of the same city Installed 

 llie system last spring, 'llie economic results 

 following the installation of the condenser trap 

 at the above Institutions led to the adoption 

 of the system by a number of the large manu- 

 facturing plant- in the same lerriloiy.
