Specification of Letters Patent.

Application filed July 19, 1911. Serial No. 639,270.

To all whom it may concern:

Be it known that 1, JOHN H. GRISSINGER, a citizen of the United States, residing at WVellington, in the county of Lorain and State of Ohio, have invented a certain new and useful Improvement in Gas-Producers, of which the following is a full, clear, and exact description.

This invention relates to improvements in apparatus for producing a fixed gas from crude oil.

The object is to provide a gas producer adapted for said purpose in such form that it is of moderate first cost and can be economically operated on a commercial scale.

The improvements as shown in the accompanying drawings are clearly described herein, and the claims clearly define such improvements.

In the drawing, Figure 1 is a front elevation of a gas producer embodying the invention with a part of the front of the producer broken away, so as to show some of the retorts and one side of the furnace walls in section; Fig. 2 is a longitudinal vertical section of said producer; Fig. 3 is a rear elevation partly broken away; and Fig. 4 is a plan view of the three stabilizers.

Within suitable furnace walls A, which may, for most part, be built of brick, are the fire box B, the retort chamber G, which is above the fire box; and the stabilizer chamber D, which is above the retort chamber. Within the fire box B is a burner F, or other means for supplying the necessary heat. Within the retort chamber are a plurality of retorts E, which rest upon metal beams H. The sides of these retorts are sinuous, as shown; and the retorts are gradually widened from bottom to top. When a plurality of these retorts are placed side by side within the retort chamber, as shown, there will be between them sinuous flues K, which will be gradually decreasing in width from bottom to top. It is through these flues that heat from the fire box flows upward in intimate contact with the retorts and into the stabilizer chamber; and because of the sinuous form of the side walls of the retorts, these side walls have more surface exposed to the action of the heat than would be the case if the walls were straight. The ends of these flues at both the front and rear of the furnace are closed gas which by sinuous strips G of asbestos or other suitable refractory material. Plates M of similar material formed with sinuous inner faces are secured in the side walls of the furnace adjacent to the two outside retorts, so that there will be formed between these outside retorts and said plates sinuous flues like those between the retorts. The strips G which form the ends of the several fiues may be held in place by plates of asbestos or other suitable material secured. in metal frames P at both the front and rear of the furnace. The upper walls of these frames are a considerable distance above the top of the retorts and these asbestos boards M extend to this upper wall, so as to form a part of the front and rear walls of the stabilizer chamber. These frames are formed by outwardly projecting flanges on vertical plates secured to the front and rear furnace walls.

Each retort E is divided by horizontal partitions e which alternately extend from the front and rear walls nearly to the opposite walls. This forms a plurality of horizontal compartments which are connected in series,the connections being around the ends of said horizontal par titions. A mixture of oil spray and air is delivered through the front wall of each retort from an atomizer Q into the lower compartment of said retort. Each retort at its rear end is enlarged downward so as to form at the rear end of the bottom compartment a settling chamber for the reception of the non-violatile constituents of the oil. Each settling chamber is provided with a clean out pipe N, connected with its rear wall and near the bottom. As the mixture of oil spray and air discharged from the atomizer flows backward and forward they finally reach the upper compartment of each retort. From this com artment the has been produced, ows through a pipe 0 upward into the stabilizer R.

Clean out pipes P are secured to the retorts in line with several horizontal partitions therein, and easily removable caps 32 are secured over the ends of these cleanout pipes. There are three stabilizers R, R and R Each is a metal compartment which extends crosswise of the stabilizer chamber D, and has end brackets which rest on metal beams a set into the side walls of the furnace. Each retort discharges its gas through a pipe 0 into the stabilizer R. The V two outside stabilizers R, R engage with asbestos plates which project into the stabilizing chamber from the side walls of the furnace. The gas formed in the various retorts is delivered through numerous pipes 0 into the rear stabilizer R. It passes from this rear stabilizer through a pipe 7' located near the middle thereof into the middle stabilizer R; and it passes from the middle stabilizer R through two pipes r, 7" located near the ends. thereof; and is delivered into the front stabilizer R and from this stabilizer it is drawn off through the centrally placed pipe 9' \Vithin the stabilizer chamber and directly over the stabilizers is a battle plate T made of asbestos or other refractory material which is suspended by bolts i from the furnace dome.

In operation the combustion of gaseous or other suitable fuel in the burner F produces the necessary heat to operate the vaporizing retorts E above the burner, the heat and products of combustion passing up through the sinuous and gradually diminishing lines or passages K between the retorts, then over and around the stabilizing chambers R above the retorts, thence out through the chimney at the top of the furnace hood. This heat maintains the retorts and the stabilizers at a proper temperature to decompose or vaporize suitable mixtures of oil and air sprayed into them at their lower ends by atomizing injectors Q, which are pipes connected to any suitable source or sources of supply. The retorts are preferably charged at their lowest points, which being nearest the burner F, are the hottest, and consequently the most effective in the initial stages of volatilizing the heavy spray-mixture, expanding it and reducing its specific gravity so that its own buoyancy assisted, perhaps, by pressure,incidentally generated in the closed retorts will cause it to rise up through and out of the retorts, and thence through pipes O to the stabilizers above, which receive the products of the several individual retorts and mix them to uniform ity. The tortuous shapes of the retort side walls add to their heating surface area, While the tortuous flues between them which are contracted in width as they extend upwardly act tocheck the too rapid passage of the heat from the burner and give it more time for effective attack on the retort walls. In addition to having. tortuous side walls the retort-s are provided with series of internal baffle plates which extend alternately from'one end wall nearly to the other, thereby greatly lengthening the retort passage and causing the gases to traverse back and forth the length of the retorts many times before passing out to the stabilizers. The increasing width from bottom to top of the retorts not only narrows the outside heat fines but, also enlarges their own internal above that a stabilizing chamber,.a

passages thereby affording space for the increasing attenuation and expansion of the gases in process of manufacture.

' This apparatus has very great producing capacity in proportion to the small space it occupies.

Having described my invention, I claim: 1. In a gas producer, the combination of a plurality of retorts fixed side by side within the furnace wall, each retort having sinuous sides which gradually approach each other from the top downward, thereby forming between adjacent retorts sinuous. flues of decreasing width from bottom to top, and strips of heat resisting material packed between these retorts near and around the ends thereof and forming the ends of said fines,

2. In a gas producer, the combination with furnace walls, within which is a fire box and above that a retort chamber and above that a stabilizing chamber, a plurality of retorts fixed side by side within the re tort chamber, each retort having sinuous sides which gradually approach each other from the top downward, thereby forming between adjacent retorts sinuous fines of decreasing width from bottom to top, strips of heat resisting material packed between these retorts near the ends thereof forming the ends of said flues, and plates of heat resisting material secured to the furnace walls over the ends of the retorts and engaging the said strips to hold them in place. 3. In a gas producer, the combination with furnace walls, within which is a. fire box and; above that a retortchamber and above that a stabilizing chamber, a plurality of retorts fixed side by side within the retort chamber, each retort having sinuous sides which gradually approach each other from the top downwards, thereby forming between adjacent retorts sinuous fines of decreasing width from bottom to top, strips. of heat, resisting material packed between these retort-s near the ends thereof forming the ends of said flues, stabilizers within the sta bilizer chamber-connected together in series, pipes connecting the upper ends of'the said retorts with the rear stabilizer, and. a plurality of atomi'zers for discharginga mixture of oil and air-into the lower ends of the several retorts,
