Description

Gas generators for motor carriages are known with a metal fuel tank and a non-lined back combustion shaft with a double casing, air supply to the center and around the periphery of the combustion zone, and venting through the ashtray perforated bulkhead, and the grate being moved in the vertical direction.

The proposed design of the gas generator makes it possible to use fuel with a high percentage of moisture, different rocks and density, which is achieved by the ability to change the cross section and height of the hearth shaft, apply to the fuel, remove and condense water vapor of the fuel and regulate the combustion process, controlled from the outside additional inflow of air into the second from the burning of the mine.

The proposed gas generator is intended to generate power gas from wood waste, which drives the engines of automobiles, tractors, truck locomotives, boats, mobile electrical installations, etc.

In FIG. 1 shows a longitudinal section of a gas generator; FIG. 2 is a section along the line AB in FIG. one.

The proposed gas generator (FIGS. T and 2) consists of the following main parts: fuel tank 4, combustion shaft 7 / with lifting grates 22, outer casing 74 with charging hole 7 and ash box 72 with hatch for clean1 {and grates, dust separation cone 9 and a suction port J9.

The fuel bunker 4 consists of a metal cylinder, terminated at the top with a conical part 75, which fits over the throat of the charging port 1. At the top of the conical part 75 there are holes 5 for the removal of water vapor. Down the cylindrical shaft ends with a conical part and a neck 77. Along the circumference of the neck there are blow holes b, overlapping and adjustable by a movable perforated ring 7i§, driven from the outside by a drive 27, 28. Between the flange and the ears 26 are supported on the flange of the socket of the combustion shaft 77 so that the top and bottom mines form a slot for the main air flow into the shaft.

The combustion shaft 77 is a cylindrical nozzle with a socket in its upper part, ending

“Flange. The lower shaft rests on the walls of the ash pan by means of a pore cone 9 with holes 20, serving as a dust and ash separator and forming a ring to receive gas. In the center of the hearth there is a vertical hollow core 25, having a bottom cut, on which a round plate-shaped spindle 22 is held by means of a nut; through the axial hole of the rod 24 in along with the burning of the shaft, the air is below the bottom. At the edge of the outer circumference of the grate, a regulating ring 2 / is fastened by means of rods 23. The grate on the rod 25 pivots through the hatch 12 and the hook O is fastened; M, fastened at one end to the ashpit wall, which is fastened in one of the openings of the grate. A conical ring 10 is inserted into the shoulders of the socket inside the chamber to adjust the cross section of the shaft.

The casing 14 of the upper shaft is a cylindrical case with a flange turned down at the bottom on which the pressure ring 8 rotates; by means of this ring, the cover is bolted with an ash pan. In the upper part, the casing 14 ends with a conic neck having a ring 2 on top, which is hermetically closed with a lid. On both sides of the casing, against the air gap of the shaft, there are hatches 16 for observing the combustion in the mine, cleaning the gap, and starting the generator before starting work. Approximately in the middle of the drought, nozzles 15 are placed for connecting pipes that supply air to the combustion pit. Inside the casing; strengthened to the wall of the annular chute 29 to collect condensed water and tar, which are brought out through the tube 30.

Zolnikova; the box in the upper part is terminated by a flange, which fastens with the casing of the shaft; in the lower part it has a flat round bottom. To clean the ash and the grate, there are two hatches 12, one under the grate, the second above it. A ring-corner is riveted to the inner wall of the ash pan to support the cone 9 supporting the entire shaft. Between the cone 9 and the walls of the ashpit there is an annular gasoline-receiving space bounded by

on top of the annular sheet 7, which rests on the inside of the center flange and externally clamped between the flanges of the casing and the ash pan. From the gas receiving ring, the gas is removed by a nozzle 19 connected to the pipelines of gas purifiers.

Before starting the gas generator, it is necessary that the hearth be filled with charcoal slightly above the air gap. The rest of the fuel tank 4 is filled to the top with fuel (fine firewood, chips, waste, etc.). Then, air suction or blowing it through the air gap of the shaft is installed, the hatches 16 are opened, the flames of a torch or other kindled kindling are opened to the gap, and after the coal has burst, the hatches 16 are closed. When the coal in the lower shaft is burnt, the burning temperature is required; mainly in front of the gap, try gas in the pipelines, which should burn with a blue-violet flame, which indicates that the gas generator is ready for action. The gas is introduced into the engine cylinders through a special mixer, where it mixes with air, to form an explosive working mixture. The fuel, as it burns, is put into the platform through the hatch with a lid / without stopping the motor. Water vapors from the fuel are collected at the top of the fuel tank 4 and the holes in the ring space of the bunker and casing are drawn through the holes 5, where, condensing on the wall of the casing, they drain down, are retained by the chute 29 and are brought out to the outside through the tube 30. This makes it possible to use fuel increased moisture. The air entering the mine gap is first heated, bypassing the wall of the gas purifier; then heated, enters the hole, 15, is still heated, in contact with the neck of the upper shaft 17 by a separating sheet 7. The gas is sucked through the pipe 19 from the ash space, which can be filled with catalytic material. Cone 9 with apertures 20 serves as a gas filter, cleansing it of ash particles, besides it is an screen, lowering the heating of the ash pan, it is possible for gas to cool somewhat and be cleaned before leaving the gas generator. The grate is designed in such a way that gas is taken into the annular space between the grate and the lower edge of the hearth; therefore, there can be no clogging of the gas receiving point, since ash and other clogging substances spill through the grate to the bottom of the ash pan. To adjust the cross-section of the hearth, rings 10 of different sections are inserted, depending on the fuel burned in the gas generator. The depth of the combustion shaft // from the air gap to the grate can be adjusted depending on the fuel by raising and lowering the grate on the rod 25, and the annular space for the gas between the grate and the bottom of the shaft does not change due to the grate connected to the grate , followed by, held by the rods 23, than lengthens the neck 11. To create an intense combustion mainly after the combustion of the shaft, air is fed into the middle of the hollow column 25, at the upper end of which there are Khodnev 5dl air openings. In order to increase the ca. burning, it is possible to give air additionally to the openings b by adjusting their size with a bored ring 18 and a drive 28 outside the gas generator during operation.

The subject matter of the invention.

1. Gas generator for motor carriages with a metal fuel bunker and a non-lined reverse combustion shaft, with a double casing, supplying air to the center and on the periphery of the combustion zone and venting through the ashtray perforated bulkhead, and with a grate moving in vertical direction, characterized by that the upper part 13 of the fuel bunker 4 is provided with openings 3, in order to drain moisture evaporating from the fuel into the space between the bunker 4 and the outer casing 14 and to bring condensate out to the outside using jolo ba 29 and tubes 30.

2. With the gas generator mentioned in paragraph 1, the use of interchangeable conical rings fO with a different spherical conical part to change the cross section of the combustion shaft 7 /.

3.When marked in p.p. 1 and 2, in the gas generator, use of a perforated ring f8 rotated around a vertical axis, covering the blowing holes 6 and designed to shut them off and adjust the degree of blow.
