5 fuel to be used in a furnace for the purpose of heating water and generating steam, my invention particularly applyln to hot water and steam heating systems. further object -,of the invention is to utilize the hot water and steam of the system for pre-heatnation. A further object of the invention is to provide means whereby the hot water 1s kept circulating around 'a fuel c ondult for re-heating the fuel a long time after the urnace itself has been disconnected from the fuel sup ly.

Further o jects and advantages of my 1nvention will appear as the specification proceeds.

The preferred form of my inventlonl 1s illustrated in the accompanying drawing which shows diagrammaticallyl the entire stem in side elevation. While I have shown only the preferred form of the invention, I wish to have it understood that various changes or modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

Referring to the drawing in detail, it will be seen that fuel oil is supplied to the furnace 1 from a fuel oil reservoir 2 through the pipe 3, a pipe 4 being provided for returnmg fuel not used.' The furnace is suitably constructed for heating water and for generating steam, and the steam is guided to a heating system through the pipe 6 and "\\is returned from the heating system through e pipe 7. The heating system itself is not fown in the drawing. The hot water is 'conducted to a storage tank (not shown) through the pipe 8 and returned from the storage tank through the plipe 9.

The ipe 3 presents a orizontal section 11 whic passes through a cylindrical retort 12, suitab e unions 13 bein provided for facilitating the assembly an packing means 14 for rendering the fit steam and watertight. Hot water is taken from the pipe 8 and is conducted through a pipe 16 to one end of the retort 12 while the other end of the retort 12 is connected through a pi 17 with the furnace, so that water may, reely circulate through the retort and return to the boiler in the furnace. A valve 18 controls the pipe 16 and a valve 19 controls the pipe'17.

The pipe 7, being the return steam pipe, is connected through a-pipe 21 to the retort 12 and includes an expansion chamber 22 rising vertically from the retort. The expanslon chamber is provided with an automatic air relief valve 23 at the end of a pipe 24 connected to the lower end of the expanson chamber. A valve 26 controls the pipe 21. A suitable drain cock 27 is pro- 'vided at the bottom of the retort 12 and a thermometer 28 allows the temperature within the retort to be established.

In usin my system it is apparent that the 'oil be ore it reaches the furnace'is preheated by passing through the retort 12. Water passes from the pipe 8 through the pipe 16 and the retort, for pre-heatin the oil flowing through the pipe 11 an the water returns through the pipe 17. Steam is conducted through the pipe 21 and the expansion chamber 22 into the retort and also returns through `the pipe 17. When the steam enters the expanslon chamber 22 it rst drives the air out of the said chamber through the relief valve 23. When 4 the fuel supply is turned olf, generation of steam is discontinued and the steam in the chamber 22 condenses and creates a vacuum which draws on the heated water in the retort 12 and causes the retort to ebb back and forth for a number of'hours after the furnace has :been disconnected. The arrangement of the valves allows either steam or water to be used singly for pre-heating the oil or in combinatmn.
