SPECIFICATION forming part of Letters Patent No. 499,339, dated J' une 13, 11893.
Application filed April 22,1892. Serial No. 430,271. (No model.) y
To all whom it may concern;
Be it known that I, IsAAe N. GORDON, of Bellefonte, in the county of Centre and State of Pennsylvania, have invented a new and useful Improvement in Heating Systems, of
which the following is a full, clear, and exact' description, reference being had to the accompanying drawings, forming part of this specification, in'which- Figure 1 is a diagram View illustrating my improved system; and Fig. 2 is a similar view of a modified form of the same.
My invention relates to the pumping systems employed for draining the condensed water from heating coils or radiators, and it consists principally of a boiler, a steam-pump, an exhaust pipe leading from the steam cyl inder of the pump to the heating pipes or coils, a by-pass pipealso connecting the heating pipes or coils with the boiler, a returnpipe connecting the heating pipes or coils with the pump-cylinder, and a return-connection between the pump-cylinder and the boiler adapted to return tothe latter the steam and water from the heating-coils.
In the drawings, in which similar numerals indicate corresponding parts, 2 indicates a boiler which is connected to the steam cylinder of a pump 3 by a valved pipe 4. From the steam-cylinder the exhaust steam passes through the pipe 5 to the heating coils 6, 7 and 8, while abranch pipe 9 directly connects the pipes 4 and 5 and leads the steam directly from the boiler to the coils, a reducing valve 10 being employedto reduce the pressure of thesteam and prevent such back pressure in the pipe 5 as would stop the working of the pump. From the coils the pipes l1 and 12 lead to a receiver 13 for the saturated steam and Water of condensation and this reservoir is connected with the pump-cylinder 14 of the pump by a pipe 15. A valved discharge pipe 16 leads from the pump-cylinder to the boiler and directs the steam and water back into the boiler. In the form of Fig. 2 the arrangement is substantially the same, except that a separate pipe 17 conducts the steam from the boiler to the heating coils.
The operation is as follows :-The pump being actuated by the steam passing to the steam cylinder, the exhaust steam passes therefrom to the coils through the pipe 5, together with the steam of reduced pressure passing through the valve 10. From these coils the steam and water ofv condensation are drawn through the pipe 15 into the pump-cylinder, and thence forced into the boiler, and the piston in the pump-cylinder moves in unison with that in the steam-cylinder, the waste steam and water being admitted upon the same side of the pump piston as that of the live steam upon its piston. As the pump is run continuously, in practice no water accumulates in the receiver, but a constant circulation of live dry steam is induced in the coils and connecting pipes, and hence the coils heated to a much higher point than was before possible, where only the water was drained from the coils and hence saturated steam was necessarily present. n
Any ordinary type of steam pump may be used, but I prefer the one in which the steam cylinder is much larger than the pump-cylinder, a proportion of two to one being usually employed, though if a high pressure in the boiler and a low pressure in the coils is desired, the proportions may be changed as desired. If the coils are of such a size that the exhaust steam is sufficient to supply them, the direct pipe from the boiler may be dispensed with.
The advantages of mysystem are apparent. A constant circulation of live dry steam is induced throughout the system, and there is no waste of steam, it passing through the heating coils and returning to the boiler to again receive its increment of heat. The system is simple and easily applied, and enables a much greater heat to be attained than in former IOO 2.
