VIEW OF THE HEATER AND BLAST FAN IN THE BOILEB SHOP (TAKEN DUBING PROCESS OF CONSTRUCTION), SHOWING METHOD OF MOUNTING HEATER COILS. the paint shop buildings and the roundhouse, the convectionmethod of heating is made use of—thpt is, blowers are usedto distribute the heat in the usual way by forcing air overthe hot water radiators, which heated air is delivered aroundthe shops by hot air ducts. In the smaller buildings, how-ever, direct radiation, without the fan blast, is depended upon;these buildings include the storehouse, the color shop, theoffice buildings, and all office and tool rooms, and the lava-tories in the main shop buildings. For the blower and, hot blast systems of heating the radi-ators are mounted in stacks within a sheet metal casing,through which the air is drawn into the fan; in this way theconstruction does not differ materially from that used with. DETAILS OF PIPE HANGERS USED FOR HEATING SYSTEM Interest will naturally center in the results that have beenobtained from the actual use of this system in heating theshop buildings during the past severe winter. The diagramon page 222 is a valuable record in this connection, as it illus-trates graphically the remarkable performance of the heatingsystem during the month of February of this year, having beenprepared especially for this purpose from the regular seriesof leadings of interior and exterior temperatures. The lower curve of this chart was plotted to indicate thevariation of the outdoor temperature continuously from dayto day throughout the month; while the upper curve showsthe range of temperatures recorded in the main shop buildingin similar manner continuously. These temperatures wereascertained and recorded hourly by the heating system attend-ants in the power plant, throughout the 24 hours of each day,and thus present a very close record of events.
