The fecd pipe was 2" in “ator was suyclied from the hesterg throuzh a pump. Coal was fed b; e Jones Underfed Stoker, regulated by Cole eutoereculator; forced draft was furnished by an 4merican blover. shree separate, eight hour tests wore planned, one to run at f:proximately one third load, one st two thirds and one eat full load. ecompanying drawings show details of the boilef and connections. Object of Tests. his type of boiler being comparatively a nev one, it was desirous of noting its action under load conditicns and determining: l= Lorsepower doveloped. 9 Ze Evaporation per pound of coal. S=- Thermal efficiency. the arparatus employed for the determination of these conditions were: le Shree U tube draft gauges.

The depth of fire and ’ water level were noted oorefully end the test was started. f The coal was wolshed on the floowr ond shoveled into the hoppers. Somples of coal were texen at regular intervels and aftor weiching were placed in a warm place to dry and woighed again after £4 hours, to dctormine moisture per. sent. ater was run into the calibratod steel tanks, weljshed by volu:e and temperature method snd pumped into the boiler. ¢ All records were tei:en every 20 minutes, except the flue gas anol;sigs, combustion chamber temperature, barometer and outside tomporature. g The resulta of the tests srewritten up in accordance with the avtandard shorteform, advised by the Hoiler Testing Committee of the a Cc: Tt 35 ine is @ a3@ 16 , v a , Tra@al llumper 1. e PATA AAD RESULTS C* EVATCRADIVE Phy AVOCRDIIG GO he SS.
