PATENT ARTHUR GRAHAM GLASGOW, OF LONDON EN GLAND, ASSIGNOR TO HIM- SELF, AND ALEXANDER O. I-IUMPI-IREYS, OF NEXV YORK, N. Y

FEED-WATER HEATER FOR GAS-MAKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 586,968, dated July 27, 1897. Application filed October 16, 1896. Serial No. 609,052x (No model.)

To all whom it may concern.-

Be itknown that I, ARTHUR GRAHAM GLAS- GOW, a citizen of the United States, residing in London, in the county of Middlesex, England, have invented a certain new and useful Improvement in Feed-Water Heaters for- Gas-MakingApparatus, of which the follow feed-water of the boiler.

In the manufacture of gas for general distribution it is the usual practice to cool the newly-manufactured gases down to about 60 Fahrenheit before passing them to the holder or mains, and this cooling is not infrequently eifected in surface condensers, the hot water coming from which is allowed to run to waste or is cooled for reuse, and the principal object of my invention is to utilize this hot water as feed-water for the boiler.

It will be obvious that no fixed relation exists or could exist between the quantity of water required to feed the boiler and that needed for cooling thegas. Indeed, the quantity of water required for each purpose will very frequently vary, and vary not infrequently in inverse relation the one to the other; and my invention consists in meeting this condition of use by providing a well or receptacle to receive the hot water from the surface condenser and to serve as the feedwater reservoir for the boiler, and in providing this well, in addition to its connections, with the condenser and the boiler with a wastewater overflow by which the water contained in it can escape when it exceeds a determined 1 height, and with a supplemental water-supply pipe provided with a valve which is opened or closed in accordance with the level of water in the well and by which any deficiency in the supply of water coming from the condenser can be made up.

Reference being now had to the drawing, which illustrates my invention as applied to a water-gas apparatus of familiar type, and in which A is a generator having gas takeoff pipes B and B leading from its bottom and top, I? and 1) indicating valves in these takeoff pipes, both of which, the pipe B directly and the pipe B through pipeB connects with a single pipe B whichleads into the top of the carbureting-chamber C, from which the gases pass through pipe D into the bottom of the fixing-chamber E, whence the blast-gases escape through pipe F into the stack G, and when water-gas is being made it passes through pipe H to the washer I, thence through seal-box J and pipe K to the scrubber L, and thence through pipe M through the surface condenser N, from which it passes through pipe 0 to the necessary apparatus, receiver, and mains. The surface condenser N is of usual construction, having at each end of the portion through which the gases pass heads M and M these heads being connected by water-pipes M passing from the water-receiving chamber N to the water delivery chamber Nflwhich, in the construction shown, serves as the well or receptacle from which the boiler draws its feedwater.'

0 indicates the supply-pipe, through which water is forced into the condenser.

P is the overflow-pipe, by which water can escape from the well N when it exceeds a determined height.

Q is an auxiliary or supplemental supplypipe leading into the well N and having a cook or valve Q, opened or closed by the float Q in accordance with the height of Water in the well N R is the feed-water-supplypipe,which leads to the boiler T, S being a feed-water pump, and the portion of the supply-pipe leading from the pump to the boiler being marked R.

T indicates a steam-pipe leading from the boilerand connecting through branches T and T with the pipes B and B, A indicating a valve by which the steam can be directed into either branch T or T or out off from both at will.

U indicates the air-blast-supply pipe, and U, U and U branches thereof leading to the various parts of the apparatus where air is from time to time required.

The gases generated in the generator A, after passing through the carbureting and fixing 0r superheatin g chambers and through the washer and scrubber, pass through the surface condenser N and are cooled by the water forced upward through the pipes N the heated water from these pipes passing into the well N which is conveniently placed, as shown, upon the top of the carbureter, but may, if desired, be in any other position. From this well the pump S constantly draws feed-water for the boiler through the pipe R, and in case the supply of water to the boiler is excessive the excess escapes through pipe P, while ii. the supply from the condenser is not sufficient to feed the boiler the falling of the water in well N will throw the action of the float Q upon the cock Q and permit additional water to flow from pipe Q into the well until the normal height of water is secured therein.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

In combination with a gas-making apparatus and a steam-boiler a surface condenser forming a part of the conduit through which the hot gases pass after leaving the gas-making apparatus, a well or receptacle as N" arranged to receive the water passed through the condenser for the purpose of cooling the gases, a supplemental water-supply pipe as Q opening into said well, a cook or Valve Q situated in said pipe Q and controlled by the water-level in the well, an overflow as 1 arranged to permit the escape of water from the well when it reaches a determined height therein, a feed-water pipe as R leading from well N to the boiler and means as pump S for forcing the heated water into the boiler.
