STEAMSHlP-FURNAGE.

Specification ofLetters Patent.

Patented Oct. 28, 1913..

Application filed August l?, 1912. i Serial No. f715,576.

To all LU/72.07211, t may concern Be it knownthat l, CI-Iannns A. K'UENZEL, a citizen of the United States, residing at lhiena Vista, in the county oi" Chaffee, State of Colorado, have invented a new and useful Steaniship-Furnaee, ot which the following is a specification.

My invention consists of an improved gasgenerator and iurance for the boilers of a Steamship employing oil as a fuel.

lt further consists oit improvedmeans for protectinpd the generator..

lt further consists ot improved means tor distributing the oil.

It further consists ot other novel features ot construction all as will be hereinatter fully set forth.

'lhe invention is satisfactorily illustrated in the aceompanying drawing, but the im port-ant instrumentalities thereof may be Varied, and so it is to be understood that the invention is not limited to the specilic arrangement and organization shown and described.

Figure l represents a somewhat diagrammatic side elevation et portions ot the hull otl a steamship equipped With my improved gas generating apparatus. Fig. 9. represents an enlarged sectional View of the generator.

Similar numer ls ot reference indicate corresponding parts in the figures.

Referring to the dra-Wings, the roter-ence numeral l indicates the hull et a stearnship, in which one or more boilers, 2, of any desired or required type are mounted in any suitable or desired manner. The boiler here illustrated is ot the return-tine type, haring a furnace, 3, a bottom-tine 4l, a return-cham ber 5, tlues, (3, and a smoke-chamber, 7, trom which a stack, 8, extends. rlhe bottom-flue has a lining, 9, of refractory material, such as irebrick, in its under side to retain the heat from the products of combustion pass ing through the flue and to protect the bottom of the boiler. An ailhcoinpressor, 10, driven by steam, internal combustion, or by any suitable power, is arranged to supply air under pressure to a tank, ll, and oiltanlrs, l2, are arranged preferably in pairs, below the level ot the furnace oit the boiler. An air-pipe, la, leads from the air-tanlr and is connected by branclrpipes 13 and le", to necks, l5, upon the tops ot the oil-tanks and havingI controlling Valves 1G, at such connections. The contents of the oil tanks may Vper one, 21, cnstitutes a ifaporiZing-chainthus be subjected to airrpressure. Pipes, 17, project through the necks of `the tanks to near the bottoms ot the saine, and areconnected to a common oil-supply pipe, v18, values, 19, controlling' such connections. A retort-structure, 20, is supported in thefiiredoor opening oit the boiler-furnace, and is ot' the same construction as that disclosed in the Patent No. 1,039,549, issued-tome on September 24th, 1912, upon application, Se rial No. 646,258, tor gas Lgenerator, filed by. me on August 26th, 1911, and needs no specific description. Generally, such structure has tour horizontal chambers, the upber, the second one, 22, an air-heating chan1 ber, the tnird one, Q3, a superheating retort, and the fourth one, 24, a distributing retort, from which burners, 25, extend into the boiler-turnace- Air under pressure is conveyed trom the air-distributing pipe, la, through a pipe, Q6, to an atomizer, Q7, receiving oil :trom the oil-distributing pipe 18 through a pipe, 28, and said atomilaer in jects a jet ot mixed oil and air into one end of the vaporizing chamber, from the other end ot which the Vapor passed through pipe, 29, to a comminuting and mixing device, 30, fully described and illustrated in my said above patent application. Compressed air is conducted through a pipe, 3l, to one end of the air-heating chamber, 22, in which it is heated and then conducted from the opposite end ot the chamber, through a pipe, 32, to the comminutin?,` and inixing device, and there mixed with the heated vapor and conducted through a pipe, 38, to the superheating retort, where the is superheated and passes to the distributing retort and out through the burners to be consumed in the furnace. The retort-structure is so supported in the tire-door opening, that a space, 34, is lett open beneath the structure for admitting atmospheric air into the furnace. A checker-Work, 35, of firebricks, having openings between them is secured by a plate, 36, and bolt, 37, to the tace of the retort-structure to protect the same from the excessive heat ot the iiame in the turnace, While the bricks Will transmit suticient heat to heat the chambers and retorts and the `gases therein.

TWhen the burners are lighted after the generating apparatus has been started, the flame and products of combustion will be carried around the boiler and through the boiler iues, and atmospheric air is adinitted through the passage beneath the retortstructure to the flanies in the furnace, aiding combustion and increasing the heat of the iarnes by the added amount of oxygen.

One oil-tank may be lled While oil is being forced out from the other tank, so that there need be no interruption in the operation of the apparatus While the oil-supply is renewed, nor need the tank be filled While there is pressure in the saine. By having' the oil-tanks beneath the level of the burners and retort apparatus, there can be no flooding of the furnace from gravity if by accident an oil-valve should be opened after the apparatus is stopped, as is liable Where gravity feed is employed.

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

l. 1n an apparatus of the character stated,

a retort-structure adapted to fit in the firedoor opening of a furnace and comprising a vaporizing chamber, an air-heating chamber and superheating retorts, a burner extending into the furnace and connected to receive gas from said retorts, and a checker- Work of rebrick and supported against the inner face of said retort-structure.

2. In an apparatus of the character stated, a furnace having a fire-door opening, a retort-structure secured to it in and partly close the upper part of said opening and thereby forni an air-inlet beneath it and constructed with air and gas heating chambers, burners extending into the furnace from said retort-structure, and a iirebrick checker- Work supported against the inner face of said retort-structure.
