FRANK J. DOUGLASS, OF CHICAGO, ILLINOIS.
STEAM-HEATING APPARATUS.
Application filed June 1,
My invention relates to steam heating 'apparatus. In the fabrication of radiators, pipings, valves, boilers and other parts of steam heating apparatus certain quantities of dirt, grease, core sand, and suoli like substances are certain to be left in the different parts of the apparatus despite all efforts of manufacturers to deliver the apparatus in cleanl condition. If this foreign matter, especially where it is of a greasy character like molders sand, is allowed to enter or to remain in the boiler (and the interior surfaces of boilers, especially cast boilers, are not likely to be entirely free from such substances), the boiler is prevented from `steaming readily, the water-'line is liable to fluctuate, and the water is likely to surge out of the boiler into the supply pipe; the presence of a oating scum of a greasy character in the boiler interfering in these and in other ways with the proper operation and control of the heating apparatus.
One of the principal obgects of my invention is to prevent such Yoreign substances in radiators, piping valves, etc. from entering the boiler, and to collect such substances and discharge the same from the apparatus.
Another object of the invention is to provide means whereby the boiler itself may be cleaned, either when the apparatus is first installed or from time to time subsequently if such cleaning is necessary.
The invention is illustrated in the accompaying drawing, in which- A Fig. 1 is a fragmentary View, in eleva-y tion, of a heating apparatus constructed in accordance with my invention; and
Fig. 2 is a sectional view of the dirt trap forming a part of the apparatus.
Referring to the drawing, 10 designates a steam boiler, the normal water level in which is indicated by the line a--a. 11 indicates one of the radiators of the radiating system of the apparatus. Steam passes from the boiler to the radiating system through a steam supply pipe 12 and one or more risers 13. 14 designates the return pipe from the radiating system which (the system indicated in the drawing being a one-pipe system) is a continuation of theL supply pipe l2.
Interposed between the radiating system and the boiler, on the return side of the radi ating system, is a dirt trap 15 provided in its conical bottom with a valved discharge Outlet pipe 16. Preferably an equalizing 1926. serial No. 112,852.
pipe 16L extends from the top of the boiler .1() to the top of the dirt trap 15 so that the water level is the same in the boiler and in the dirt trap. This pipe also serves as an emergency return to the boiler in case valve 18, for example should fail to openas in-y tended. The return pipe 111 of the radiating systemy enters the dirt trap above the bottoni thereof' 4and preferably below the water level, indicatedv by the line aw-aso that the entry of water into the trapdoes not disturb any scum or floating impurities on the water standing in the trap'. A pipe 17 leads' from the dirt trap 15, below the water level therein, and preferably below-the connection' of pipe 14, but a substantial distance above the bottom of the dirt trap, to the boiler 10, this pipe 17 being provided with a cheo'kvalve 18. 19 is the water feed pipe forthe boiler and 2O a blow off pipe, these pipes being provided with valves 21, 22. f
The operation ofthe apparatus is as follows: y
Dirt, grease, scale, core sand and the like' from the piping radiators and other fittings are carried through return pipe 14 into theV dirt trap 15. Here a separation takes place. Thevheavier substances are preci itated to the bottom of the dirt trap. kT 'e lighter substances, such as grease or Adirt or sand mixed with or impregnated with grease, iioat to the top of the water in the dirt trap As aresult, only pure water flows frornthe dirt trap to the boilerthrough pipe 17. The foreign substances collected in the dirt trap may be discharged from the apparatus by opening the valve in pipe 16.
In order to remove from the boiler any grease or dirt which it may contain whenv first installed or which may subseouiently enter the boiler, valve 21 in the feed pipe 19 is opened with the steam in the boiler at a low pressure, but with the fire under the boiler going. The water is let into the boiler rather slowly until it is completely filled and overflows into the steam supply pipe 12. In this way, any scum that there may be on the surface of the water in the boiler is carried over into and through the supply pipe and thence to the dirt trap 15. The valve in the discharge pipe of the dirt trap is opened so that any foreign matter entering the dirt trap is discharged therefrom. The dirt` trap dr'ain valve is then closed, the valve 21 in the water feed pipe closed and valve 22 in the boiler or blow-oil?- pipe :2O opened, so as to reduce the water level in the boiler to the normal level.
The invention is shown and described in a preferred embodiment, but the intention is to cover all modilications within the scope of the appended claims.
